Tire questions

[mrlmd1]

I recently got a '99 GZ250, has about 2950 miles on it, took the MSF course, etc, have been doing some local riding, practicing, etc, before I go into town or on the highway, getting my skills up. The tires have lots of good tread, barely used, but being 8-9 years old, have developed small cracks, crazing here and there, in the sidewalls, and are a little hard, from being outside. If this was in my car I wouldn't worry about it yet, but the smartest thing to do would be to get a new set put on the bike, as I don't want a tire failure at 50-60 mph. I'd love to buy these online because I'd probably save myself 25-40% of what the local Suzuki stealer or other bike shops charge, but then I'd probably have to search around for someone to change them out for me, and maybe pay for shipping (some sites have free shipping) and buy some tools, etc., so the cost may come out to the same thing.
I guess I could ask the bike shop if they'd put them on if I supplied them, but I doubt they would like that idea.
My other choice is to ride on these for a while, not knowing how long I'll keep this bike before possibly moving up to a bigger one sometime in the future (if a tire doesn't blow out on the road).
Any suggestions as to good inexpensive tires for this thing?
Does anyone have experience with H rated Cheng Shin tires, which are about $40-50 less than Dunlops or Bridgestones?

Thanks.

You're situation with tires sounds exactly what I experienced. I bought my 2000 GZ250 in December. It had around 2000 miles on it and the tires looked OK, except they were cracking on the sidewalls. I felt it would be wise to go ahead and replace the tires instead of taking chances that one might blow. I bought the Cheng Shin tires and I think they're great! I've put about 300 miles on them so far and I'm very happy with them. They seem to handle well in the curves. I purchased mine from a local bike shop and then had them install the tires. I thought about doing it myself, but it seemed like more trouble than it was worth. The install cost was around $25/tire.

[davidc83]

I have the Cheng Shin tires and I am satisfied with them. I have good traction and disperse water extremely well (rooster tails) off the back tire. I also have a C50 and plan on putting tehe Cheng Shin on them also. Here is a good website for them: http://www.kgmotorcycletires.com/cheng_ ... 6_c907.htm (http://www.kgmotorcycletires.com/cheng_shin_c906_c907.htm).

You can purchase them and have any local bike shop put them on. They will charge you for it with no complaints. Money is money. Expect to pay $25-$37 per tire for mounting and balancing. You may have to take the wheels off though. No big deaL, easy.

[mrlmd1]

I think I'll try and find a bike shop here that'll mount and balance the new tires, and I'll buy them online. I can take the wheels off, and it would give me a good opportunity to clean the chain, but then I'll need some sort of stand. It never ends, does it?, just like owning a boat.

[Badbob]

I've bought 5 Cheng Shin tires and they work well for me. They last longer than the stock tire that came on my GZ250.

[Jaime]

You can use a regular jack from a car to lift the front and rear wheels, helped by the kickstand.

Rear:

[mrlmd1]

What do you put the bike down on if you take of both wheels? Or do you do this one at a time?
I suppose I can rig up something to put under each end then jack up the other if both wheels are off.

[Jaime]

You can keep the bike lifted with two jacks and the kickstand (I did it), but it's better to change one tyre at a time, keeping the mounted wheel braked.

[mrlmd1]

I just got an email response from swmototires.com saying they don't carry Cheng Shins because they get hard very quickly. Does anybody have a problem like that? That has to relate to poor traction especially around curves after a while.

Jaime, thanks for the pics. I do have a couple of those scissor jacks around. After getting the bike up, it could be supported on something more solid underneath it if need be and tied down so it won't fall over.

[Badbob]

Not me I wear mine out way before that happens.

Never heard this when I was researching tires to buy.

Here is where I got the last ones.

[mcintyre_aerospace]

I have cheng shins on mine, and im pretty satisfied. Plus I only spent around 60 dollers for both. I didnt want to use a jack on my bike, so I took the seat and trunk of the bike and used an engine hoist with a strap around the frame. I lifted the back off the ground then set the wole bike on a big truck tire. The engine hoist also keeps the bike upright so no falling over. I also got a chain with a master link, it makes the job easier ad their cheap. I didnt get an O-ring chain, I dont see much of a difference, and i oil it about ever 2-3 weeks with 80-90W gear oil. I mounter my tubes and tires myself, its pretty easy, but I had to drive 115 miles to balance them.

[Badbob]

I like the hoist idea. I do that for my lawn tractor but never thought of using it for the motorcycles.

I never balance my tires. I can't tell the difference.

O-RIng chains last longer.

[mcintyre_aerospace]

My front tire was seriously off balance. From about 20mph to top end, the bike would hop and shudder pretty bad. It also makes the tires last longer when their balanced.

I have no experience with this vendor but I found their pricing.
C906 front $50.65
C907 rear $50.53

I need tires too, but I'm a little leery of the cheng shin. Can't beat the price though. Does anyone have any experience with other tires that they would recommend?

BTW I thought I throw out this important safety reminder. There usually is mold release on new tires. be very careful for the first 100 miles or so. The mold release makes the tires very slippery. This can be made worse if you ride on wet pavement!

[jonathan180iq]

Babbob has several Cheng Shin tires, I believe it's 5, and seems to like them just fine.

If you search through his posts you should find 'em.

[Water Warrior 2]

That brand has been around for 20 years or more so they must be doing something right. My only experience was with a rear digger tire on a dirt bike and was well satisfied. Half the price of OEM tire.

[Badbob]

Here is where I bought the last ones. I went with this company because they had everything. Only one shipping charge to pay.

I'm on my second rear tire. My wife has a matched set. My daughter has them and my son-in-law. We all like them.

[turbo chicken]

i ended up ordering some from the cycle gear shop around the corner from my house... i got Cheng Shin (different model tire though) each one cost about 5.00 more. I figured i'd support the local shop, the guys at the shop are good to me and have gone above and beyond with their service recently. They didn't even throw a fit when i didn't purchase that they had in stock that came in at about 90.00 a tire...

with tires, tubes, rim strips i ended up at about 170.00 after taxes.

[Sarris]

I use Metzeler or Pirelli touring tires on all my bikes. I'e gotten great mileage in the past (8 to 10k on a set) and they have great straight line & cornering grip.

The set I just put on the GZ was a Pirelli Route on the rear ($107.65) and the Pirelli Sport Demon ($90.57) on the front. (the Route model was not available in the correct front size) The tubes were $8 each.

I have a couple of pals with the Cheng Shins that have had sidewall problems, so I stick two the above mentioned brands.

:tup:

[jonathan180iq]

It might be a good idea to list every available tire for the bike somewhere on here...
And possibly add photos of the tread pattern...

[hippybilly]

I'm just gona make me a sling and use the front end loader on the tractor to jack my bike up with. One of the benefits of farming :tup:

[mrlmd1]

My local Suzuki dealer got 2 new Cheng Shins for me that they are putting on, (with tubes, rim strips, balancing, etc, for $169) but the front tire, instead of being a 110-90/16 is a 120-80/16. They are telling me it really makes no difference in the handling, ride, etc, to change to a slightly wider, lower profile tire, and that they would have a hard time getting the other size and it would be more expensive. Anyone have any experience with putting on this other tire or any comments about this? I doubt it would make a significant difference with the speedometer reading but it should read a little higher with a slightly smaller diameter tire.

[jonathan180iq]

Those two tirse sizes will end up being fairly similar. I ran the numbers through a tire size calculator and this is what it came up with:

Specification----Sidewall--Radius---Diameter---Circumference-Revs/Mile---Difference
110/90-16-------3.9in-----11.9in------23.8in------74.8in------------848----------0.0%
120/80-16-------3.8in-----11.8in------23.6in------74.0in------------856----------1.0%


http://www.miata.net/garage/tirecalc.html
Scroll down and use the calculator at the bottom

[Easy Rider]

They are telling me it really makes no difference in the handling, ride, etc, to change to a slightly wider, lower profile tire, and that they would have a hard time getting the other size and it would be more expensive.

Bunch of crap. They want you OUT the door....minus your money! :cry:

There might not be MUCH difference in handling but there surely will be SOME.
I think tread pattern probably makes a bigger difference that size.
Please let us know what YOU think after a ride or two.

The last time I changed to a different brand of tires, I could have sworn that it was a different bike. O_o

Well that just sucks. Now we will have to pay twice as much for a tire that isn't any better.

[samato]

I was just about to place the my order online today for tires, tubes, and rim strips at http://www.kgmotorcycletires.com/ and decided to call to make sure they had these in stock:

M906602 Cheng Shin C906 110/90H16
M907501 Cheng Shin C907 130/90H15

It turns out that they DO NOT and WILL NOT have them anymore! The guy told me he used to be able to get them from 5 different distributors but now he can't get them at all. My guess someone is buying up all that are out there so they can sell them for more.

Bad news for all of us who want a decent, inexpensive tire. So far I can't find anything for less than $95 in the right size for the front (110/90-16).

Is it a bad idea to buy different brand tires for front and back, for example Kenda rear and Avon front?

[jonathan180iq]

It's not really "bad" as long as get the same style tread pattern.

You want to know that the front and rear of the bike will maintain the line similarly in a turn or when you hit those staight grooves in the road. It can be pretty scary having one end on the bike twitching around while the other stays in place.

I really do think that the smaller front would be OK, but I just can't say for sure and I don't want to put anyone in a bad spot if I am wrong. I'd hate to cost someone the money and, very doubtfully but at least possibly, put them in danger.

[mrlmd1]

Well I got my bike back 2 weeks ago and the Cheng Shins came from California here to the local dealer. They put the 906 and 907 numbers on the invoice, but the front tire is now a 120/80-16 as discussed and not a 110/90-16. Apparently that is not available anymore anyplace. In my limited riding so far I can't tell any difference in the bike's ride or handling, except they look a whole lot better, and I feel a whole lot better having new tires instead of 9 year old ones. The 120/80 is a little less than 0.4" wider (that's less than 1/4" on each side for the total width of the tire), so it can't make any significant difference other than having very slightly more contact area, maybe a millimeter or two. The contact pattern or dirty area on the tire seems the same as before. What is interesting is that the tires are mounted correctly with the rotation arrows embossed on the sides in the right direction, but the tread pattern front and rear is reversed, with the rain grooves pointing in opposite directions front and rear. I can post pictures if anyone's interested in seeing this. It must be different front and rear for shedding water or traction, but I thought it strange looking at it. Any thoughts on this?

[jonathan180iq]

I think I know what you are describing and I never could figure out how that works. The same it true for bicycle tires. I guess its just up to the tire design to figure what design works best for each individual application.

I, for one, will go ahead and request pictures. Nothing like a picture.

The difference between a 120/80 and a 110/90 is only 3mm. So, it should be slightly wider and not change the height much at all.

[samato]

jonathan180iq,

You mentioned that Dunlop D404 are available as a set in our sizes but I can't find a place that has the front (110/90-16). Would you happen to have a link?

Right now, I can't find any matching set regardless of price!

Thanks

[jonathan180iq]

After searching around for the last few minutes, the only version that I can find for direct purchase is in Australia. I may have to revise my posts to mention that there are no longer matching sets available for the GZ.. What a crock....

The information listed below comes from the DunlopUSA website and mentions that the only way to get the Dunlop D404 in size 110/90-16 is to order through OEM... The only direct order DunlopUS model seems to be the GT501. Dunlop certainly makes the D404 110/90 but not for us. I'll see if I can find a way to have it shipped from AU or CAN.

found one in the UK for $120.... http://www.sticky-stuff.co.uk/shopping_cart.php?sort=3a
good grief

[jonathan180iq]

If you also go with a 120/80-16 in the front, you can get a set of matching ChengShins on Ebay right now.

It looks like the problem is finding a stock front tire replacement. That's just not a readily available size.

You may just need to end up finding a close tread pattern and mix-n-match.

Sorry man...
Or go with the Kenda Cruiser set with the smaller front tire

[jonathan180iq]

Here are some:

Thanks for all the info. I'm just shocked that it's so hard to buy some stupid tires! I'm thinking about the doing 120/80-16 so I'm gonna check on eBay.

[samato]

Here are some:

I called and they don't have them either.

[Quimrider]

Let me know if you find the Cheng Shin fronts. Or for that matter any front. I'll probably go with the Continental front if I can't find the C.S. My local shop can't find any 110/90-15 tires. Good thing I still have some tread left and don't need a new tire immediately! Try googling "110/90-15" maybe that will help :)

Thanks Jonathan, I meant 110/90-16.... DOH!

[jonathan180iq]

umm... 110\90-16

[samato]

My front still has plenty of tread also but it's got some cracking on the sides. My rear basically has no tread in the middle. I'm pretty sure these are the original tires for this bike. I really need some tires ASAP and I'm going nuts trying to get them. It hasn't been easy to find inner tubes or rim strips either unless I want to buy from several different places (which I don't). This is crazy! Hopefully it won't be this hard to find front brake pads, which I also need right away.

I'll let you guys know if I have any luck.

P.S. I just installed some ammo cans as saddlebags. I used the SAW boxes. I'll post pics after I get through this tire ordeal.

[samato]

UPDATE, 8:28pm: These tires are not available either. Man, this is crazy! Looks like the only option is OEM. Something like $146 for the front and $135 for the rear. I really don't know what to do now because I can't afford that much right now but I need the tires ASAP.

--------------------------------------------------------------------------
So here's what I think I'm going to buy:

http://www.bikebandit.com/product/10843 front tire
http://www.bikebandit.com/product/3648 rear tire
http://www.bikebandit.com/product/11113 front tube
http://www.bikebandit.com/product/11109 rear tube

I can't seem to find the right rim strips on bikebandit.com so I'm thinking I might just re-use the old ones.

If anyone has comments, questions, or objections I'd love to hear them before it's too late. I plan to place my order tonight (soon).

[jonathan180iq]

As long as the rim strip isn't damaged in anyway, I would reuse it. I have done this several times on my bicycle tires.

Also, make sure that you get the version of those tires that accept tubes. The little description on the link says "tubeless".

[Easy Rider]

Well, you're gonna have to explain that to me.
I don't think anybody makes "tube only" tires anymore.......except maybe for bicycles.

Is there some reason you think that a tubeless tire will not work on a rim that requires a tube ?? :??:

[samato]

I have the same question. I thought you could just put a tube in a tubeless tire and it would be fine. Is that not the case?

[Easy Rider]

I have the same question. I thought you could just put a tube in a tubeless tire and it would be fine. Is that not the case?

Yes, I think so. That kinda was my point. Was I too subtle? :cool:

I think I understood your point. My question was aimed at other members who may or may not agree I suppose.

Well,

I've never had a motorcycle with tubes before this one and, as far as bicycles go, you never use a tube in a non-tubeless tire.

I haven't had to deal with motorcycles with tubes before. If interchangable tires are par for the course, then just ignore me.

[Easy Rider]

If interchangable tires are par for the course, then just ignore me.

That would be no fun! ;)

BTW, what's a non-tubeless tire ?? :??:

[samato]

Well, I guess I'll find out for sure in about a week because I just ordered these:

http://www.chaparral-racing.com/Chaparr ... CFFFB5AA91 (http://www.chaparral-racing.com/Chaparral/product_family.asp?family%5Fid=607&gift=False&0=assets%2Fhtml%2Fd%5Fstreet%2Easp%2CnavId%3Dd%5Fs treet%2A0%26menu%5Fid%3D%26Tree%3D%2CStreet&1=dept%2Easp%2Cdept%5Fid%3D456%26menu%5Fid%3D%26Tr ee%3D0%2CStreet%20Tires%2C%20Wheels&2=dept%2Easp%2Cdept%5Fid%3D162%26menu%5Fid%3D%26Tr ee%3D1%2CKenda%20Street%20Tires&mscssid=8F1BDABE70B94716BD4246CFFFB5AA91)

I ordered a 130/90-15 rear and a 100/90-16 front so I should be able to share some info on using the smaller front tire too. Of course, that all depends on whether or not I break or destroy anything as this will be my first attempt at installing anything but a bicycle tire!

P.S. Sorry about the crazy long link. My normal method for fixing it didn't work here.

Those Cheng Shin tires are out of stock everywhere I have checked. I am thinking of trying the 120/80 16 for the front and the 140/90 15 on the rear. My Dunlop 404s have good tread but have some small sidewall cracks. I know it will raise my final drive ratio. But not as much as a 16 toot sproket I could also mix up a set of Kendra tires but the reviews on those are not good. I would have thought a bike used in motorcycle classes and in the third world would have inexpensive tires available for it :??:

[jonathan180iq]

or any matching tires for less than $120 a piece...

[Quimrider]

I am not 100% certain on this but as far as what tires you can use a tube with, I believe the tire must be a bias ply and not a radial tire. You should be ok with any tire as long as it doesn't say its a radial.

[Quimrider]

Anyone herd anything good or bad about the Continental TKV11 110/90-16 Front. I'm considering this if I cannot find the Cheng shin tire.

[Badbob]

It turns out that they DO NOT and WILL NOT have them anymore! The guy told me he used to be able to get them from 5 different distributors but now he can't get them at all. My guess someone is buying up all that are out there so they can sell them for more.

There goes my idea for stocking up. I was thinkg of buying at least one more set of these. I'll need a front tire in a few months.

Thanks

Many sites that have the oem parts list the Dunlop front tire. For example bikebandit.com:
http://www.bikebandit.com/houseofmotorcycles/suzuki-motorcycle-gz250y-2000/o/m6287
click the "Wheels / Tires / Final Drive" Click on front wheel and it is item 10. The price is $79.89. The reason you can only find the tire as an OEM part is because Dunlop only sells this tire in that size to Suzuki as an OEM part.

Also as a side note I've been told the next shipment of Cheng Shin tires are due to arrive late this month. We'll see if this actually happens.

[mr. softie]

:) I just purchased a set of cheng shin C906/C907 tires on ebay in the correct sizes 110/90-16 and 130/90-15.
.They had a few more to sell at less than $40 a tire plus shipping ( $26.90--expensive I know). I cannot vouch for the seller but his feedback seems pretty good. I have heard the warehouses are expecting these tires this week but did not want to miss these.

I have ridden about 19,000 miles on Cheng Shin tires in all sorts of weather. Well, not snow. They worked better for me that the Dunlops that came on my bike. In my family there are four bikes wearing Cheng Shin tires. Everybody likes them.

Just in case you think I take it easy and wear my tires flat in the middle. I have very little rubber left on the bottom of my foot pegs.

.They had a few more to sell at less than $40 a tire plus shipping ( $26.90--expensive I know). I cannot vouch for the seller but his feedback seems pretty good. I have heard the warehouses are expecting these tires this week but did not want to miss these.

http://stores.ebay.com/TIRESCHEAP

I would be very interested in finding out if those tires actually make it to you. I hope they do. One ebay store I checked supposedly had them in stock but when I contacted them they informed me they did not and were not sure when they would. Anyway, I'm sure somebody has them. Please update us when/if you get them.

As for me, I just put Kenda Cruisers on. 130/90-15 rear & 100/90-16 front. Everything seems fine so far but I only have about 30 miles on them.

[jonathan180iq]

Samato,

good to hear that everything mounted up fine. Would you mind shooting a few pics of the results?

[samato]

Sure, I should be able to post some pics sometime tomorrow.

[Quimrider]

I did some searching and Cheng Shin and Maxxis appear to be one in the same company. So maybe they will sell the C906/C907 Himax tires or something similar under the Maxxis name next year.....

[Quimrider]

For everyone who has been waiting, I got the following reply from Motorcycle Accessory Warehouse:

If you go ahead and place the order it will put it on backorder. They are due in 7-18-08

Thanks,

I remember seeing something about the name change somewhere. Thanks for the reminder.

[strn365]

I just got my new set of cheng shin tires. I bought them from JcWhitney. They seem alittle soft is that normal for these tires.

[samato]

Sorry for the delay in posting these pics. There's been A LOT of rain here lately plus I had a hard time finding the cable to connect my camera to the computer. These are pics of my bike with Kenda Cruiser tires - 100/90-16 front & 130/90-15 rear.

By the way, does this look wrong to anyone? The front wheel looks like it's shifted too far to the right. I hope I didn't put it on wrong. It does seem to be centered with the fender. Is this how it's supposed to look?

[Easy Rider]

By the way, does this look wrong to anyone?

I hope it's just an optical illusion but, YES, it does not look right.

[Sarris]

Perhaps you have installed the wheel to the wrong side? Then the tire is on backwards (tread direction wise)? You wouldn't be the first to flip the rim to the wrong side.

Let us know.

:tup:

[samato]

No, tire direction is correct. Wheel direction is correct also because I did not remove the disc so it's pretty obvious where it needs to be. I too am hoping it's some kind of optical illusion. Can anyone post a similar pic of their bike to compare?

[Sarris]

I went out to the garage and looked at mine. It looks just like yours. I must be having the same optical delusion. So, I think it's OK. If you get square in front of the tire & fork, the spacer is way bigger looking on the right hand side of mine also.

:tup:

[primal]

Mine looks like that, too.

[samato]

Well that's a relief. Thanks guys!

[patrick_777]

After noticing how it looks off-center, it's gonna bug me now, thanks OCD.

[jonathan180iq]

Good looking tires. Nice to know that these will definately work. Note taken.

By the way, good looking ammo cans!

[davidsuserid]

Someone mentioned "TiresCheap" on eBay. They have a listing with 5 (now 4 since I bought one) for the Cheng Shin C906 110/90-16. I emailed them before I bought it and asked if they had them and they said yes. But only time will tell I guess. So if are in desperate want or need of a C906 tire, you may want to check them out, not a bad price either, something like $57 shipped.

[mr. softie]

I am still waiting for my tires from "tirescheap" on eBay . Seller has been communicating well, we'll see. Hoping to see them tomorrow. It as been a week and a half since I purchased them. I will post when I get them.

Just in case, I am still looking. I called traxms.com and the sales guy there said he could get them from a warehouse in Pennsylvania, for an extra $10. ($114.45 for front and rear w/shipping).

[samato]

Good luck with the Cheng Shin tires. I just did not believe anyone was actually going to be able to get them to me in the near future so I went with the Kenda's (wrong size front). Anyway here's what I paid for my order from www.chaparral-racing.com (http://www.chaparral-racing.com) if anyone's interested. They didn't have the rear tube so I bought that at a local shop. I placed the order on Thursday, 7/3/08 and received it Thursday, 7/10/08.

[samato]

Right, alternate size! :2tup:

[mr. softie]

Tirescheap came through and I received my cheng shins today. I purchased new tubes and rim strips locally. Whew! :cool:

[davidsuserid]

that makes me feel better that you got yours. They say their processing time is 3-5 days so, i will give them that before i ask about them.

[Quimrider]

I'm still holding out for the stock size CS front tire. I was looking at other sizes though and am thinking out loud. Some here have gotten 100/90-16 and I thought the 120/80-16 might make a decent alternative size as well. From the miata tire calculator page:

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
110/90-16 3.9in 11.9in 23.8in 74.8in 848 0.0%
120/80-16 3.8in 11.8in 23.6in 74.0in 856 -1.0%

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
110/90-16 3.9in 11.9in 23.8in 74.8in 848 0.0%
100/90-16 3.5in 11.5in 23.1in 72.5in 874 -3.0%

Looks like the 120/80-16 would be a better choice. just my 2 cents

[mrlmd1]

As I said on a previous post here (I also started this string), I got the 120/80 front Cheng Shins, listed as the 906 tire, from the local Suzuki dealer who ordered them from somewhere in California, and there is no appreciable difference in riding on them compared to the 110/90 's. The tires are almost identical to the original specs and I don't think any experienced rider could tell one from the other. The only thing that seemed strange to me was that the front and rear tread patterns from this 906 and the 907 I got, both Cheng Shins, is reversed, and I will post a picture later when I get out to the bike with my camera. If the 120/80s are the only thing available, I would go for them.

[davidsuserid]

My 110/90-16 Cheng Shin 906 from TiresCheap on ebay came in, to my door for $57. Email them first, I think last time I looked they had a couple left.

[mrlmd1]

The picture posted previously suggesting the front wheel is not centered on the axle is an optical illusion. If you look at the bike from the front, the brake disk fills the space on the right side of the wheel whereas on the left side there is nothing. The wheel is centered if you want to measure it from the forks on each side.

I tried going to this site (since I recently found out my front tire has cracks, but I couldn't find the model listed. Am I missing something. Attached "appears" to be the only 110/90-16 they have, or am I missing something ?? Thanks.

I went to the TiresCheap store on eBay, and I could only find the "100/90-16" size. Are tires "coded" the same way as cage tires, Like Tread Height, Width, Diameter ?? Is there an alternative size ?? Would the size attached work (found at motorcycleproshop.com advertising $9 shipping) ??

I did find the 130/90-15 rear tire on their site though, $53.00 with $17.00 shipping, advertising 100 available, FYI.

I actually did read all 7 pages !! Couldn't find the tires on the site BadBob recommended, and I'm doing my best to figure it all out, but tube sizes and rim strips got me confused. Sorry, because if my local shop doesn't stock them or can't order them, I'll be searching online, and you can get really hosed if you don't know what your ordering.

I think I'll go back through all the posts with pen and paper this time...
Thanks.

[Sarris]

Rich;

The 100/90-16 is an alternative for the 110/90-16, just a hair smaller. The first number is width in millimeters, the second is the sidewall height stated as a percentage of the tread width. The last is the rim size in inches. So, get the 100/90-16 if the 110/90-16 isn't availabe.

The 110 is 110 mm wide and has a 99 millimeter tall sidewall, the 100 is 100 mm wide and has a 90 millimeter tall sidewall. Just a little over 1/4" smaller in sidewall height.

No big deal, do it.

:)

[Easy Rider]

Sorry, because if my local shop doesn't stock them or can't order them,

These bikes are still being made and sold new. If a real Suzuki dealer says they can't get tires for a GZ250, you need to look for another dealer.......and I'd be tempted to call Suzuki. That's just plain stupid.

See the area titled "TIRES"

Called my local cycle shop, and they had a hard time finding BOTH rear and front tires. Eventually they called me back and said they could get the Kenda's, but the front would have to be 100/90-16. Each was in the $50-$60 range, but I'm sure with tubes and rim strips (??) it'll be more like $75 a piece.

I figure I'll go for it, since I've had a hard time finding replacement tires listed in the "TIRES" section anywhere online. Thanks for all the help. Let me know if anything about "availability" changes.

Soon to be riding again !!

[jonathan180iq]

We're all in the same boat as far as availability of tires change. Some people are coming across a store deep in the annals of cyberspace that have some left but on the whole they are just getting harder and harder to find. If we could find a direct link to a store in the EU we would be in business. There are a whole crap load of bikes over there that accep our tires sizes and as such they have a variety to choose from.

[primal]

It just boggles my mind that it would even be possible to have a hard time finding tires for a bike still in production...

[RichInFla]

I think I'll try and find a bike shop here that'll mount and balance the new tires, and I'll buy them online. I can take the wheels off, and it would give me a good opportunity to clean the chain, but then I'll need some sort of stand. It never ends, does it?, just like owning a boat.

The local cycle shop can find one brand, Kenda, that has both front and back (mentioned in previous post). However, they said they will mount and balance, but they won't remove the wheels and/or reassemble. I have a feeling this is out way out of my league mechanically. I could probably get the wheels off, but putting everything back together, I'm not feeling too confident. I may get my HD neighbor or guy down the street to help. If I have somebody that knows motorcycles, they should be able to help me with this right, given I have the manual to make sure chain tension, etc is within guidelines putting it back together ??

Unless anyone has a video "How To", located in their "GZ250, Mechanics for Dummies" library, LMAO...

Thanks.

[Easy Rider]

Is this a "real" Suzuki dealer ??
I repeat and emphasize: Look for another dealer.
Most would be happy to take your money for doing the WHOLE job.

Removing and replacing the wheels is not really a big deal.....if you have, oh say 10 years experience, working on cars and other mechanical things. Even a rookie can do it with a manual and some confidence. BUT.....getting them back on right is ***REALLY*** important so, yes, I would highly recommend that you get some help and/or experienced guidance.

Kudos for being able to make a realistic assesment of your own capability.
Many get in WAY over their head and THEN yell for help. :tup:

No, this is a local cycle shop, not a dealer. Local dealer in my area is called "House of Power", and I've heard nothing but bad things from over a dozen people. There may be one farther away, but I have nothing to transport it. After reading the posts, don't really want to drive it.

Heck, if you were in the area, you'd get my business !!

[Easy Rider]

Nope. I used to do all that stuff myself; not anymore. Just a grease monkey now.

So, let's take a different tact. For things like tires and chains....the basic stuff.....all Jap bikes are a lot alike.
Is there a Kaw or Honda or Yamaha dealer close by? If so, give them a call. They might be happy to get your business.......AND they might be able to find other tires too.

Good luck.
Sometimes I forget how lucky I am to have a good dealer close by.

[samato]

Any dealer or online source should be able to order you the OEM (stock) tires. If you go here:

http://www.bikebandit.com/houseofmotorcycles/suzuki-motorcycle-gz250-2003/o/m6282

and click on "Wheels/Tires/Final Drive" you will see the following:

10: TIRE FT(110/90,
(110/90-16) 1482958-001 Enter 0-99 $146.33

26: TIRE,RR(130/90,
(130/90,) 1487535-001 Enter 0-99 $139.68

For me that was too much to spend on tires so I went with the Kenda's (100/90-16).

I had no previous mechanical experience but following the owner's and service manuals plus watching some You Tube how to videos, I was able to change the tires, tubes, and rimstrips with no problem. There really is not much to it but it is better safe than sorry I suppose. It's amazing what you can learn on the internet these days. With the help of this site and You Tube I've so far been able to change the tires, oil, brake pads, make some ammo can saddle bags, and probably a couple of other things I'm forgetting. I will say that figuring out tire and tube sizes was pretty confusing for me, especially dealing with metric/standard conversion. It was also pretty ridiculous how much research I had to do just to order tires, tubes, and rim strips.

[patrick_777]

Okay, I did it. Kawasaki dealer about 20 miles away found the Kenda's. One in NY and one in NV. Ended up with the 100/90-16. I dropped her off today. This is what they were charging, just wondered if I'm getting hammered. The front tire was about $52, and the back was about $63. Tubes were $13 and $19. They charged $50 per tire to mount and balance. It was $35 if I just brought them the wheels, but in previous post, I know my limitations mechanically.
Thanks.

[Sarris]

The prices aren't too bad, they always nail you on the labor. I bought Pirelli and paid $108 for the front, $91 for the rear, $8 each for the tubes, and $25 each to mount and balance them. Total out the door including tax and old tire disposal fees was $265.

This was done at a local independent shop with a regular service so they didn't hammer me on the tire mount & balance (they normally get $50 each without the service). I did opt for high mileage touring tires. Pirelli Sport Demon in the front and Pirelli Route in the rear in the factory recommended sizes.

Glad you got her done.

:)

[Jer]

Under normal conditions how long should a set of tires last?

Do they need to be replaced at the first sign of a crack?

[Easy Rider]

Under normal conditions how long should a set of tires last?

Do they need to be replaced at the first sign of a crack?

There is no "normal", really. It depends on the tire, what pressure you run, how you ride and whether or not they are left exposed to the elements (sun being the worst) for very long.

Some wear out in 5K miles. I am approaching 5K and don't think I'm close to half.....so I should be good for about 10K miles.

And no, you shouldn't panic when you find the first tiny crack. The key word is TINY. Sidewalls will often have "spider-web" checking in the side walls. This just means you should watch them closer for larger cracks to develop.

Having said that..........many riders are riding on unsafe tires......because they are too old. They LOOK good but are hard as a rock and probably have sidewall cracks they haven't noticed. Many riders never actually wear out a set of tires.

I would never ride on tires over 5 years old, if they spent a lot of time outside......unless maybe you ride like an old granny and never go over 30 mph. Tires 7 years old: GONE regardless of how they look or how they are used.

So, if you have a 2001 bike or earlier with the original tires, tsk, tsk !! :oops:

[Quimrider]

Shame on me I'm riding on my 2000 bike with original front tire. It would have been replaced back in June if I could just find a tire. I've had the CS tire on back order since the beginning of July. I'm guessing the supply of the Cheng shin tires had dried up? Has anyone spotted the 110/90-16 C906 anywhere? I will probably end up going with a 120/90-16 cheng shin for the front. if it doesn't come in soon. If anyone is curious I got the following out of Motorcycle Warehouse:

With backorder due dates, we are in the same boat as you. We can only provide you the information that we have been provided.
At this point, the due date is now 08/10. Here is the phone number to GBC/Cheng Shin, maybe they can give you more information 310-669-2626.

God...


Tires for my little 2001 were hell to find. I ended up getting dunlops, and replacing both. I've bought the tires, but they keep pushing back the backorder date. It was the 11th, then the 15th, now it's today (the 17th). They have the front tire but waiting on the back tire.

When i asked about possibly looking for the 100/90's, he said they wouldn't put on the smaller tire due to liability reasons. I thought that was odd but slightly understandable. This is a real suzuki dealer btw.


So yeah..i went through hell on the phone (as they charge 155 for both tires if you bring them in, 55 if you buy them from the shop, and frankly don't have time to try to figure out how to put tires on, lol). Took about 45 minutes to even find tires since you can't really even get Cheng Shin. I went through the brands with him and the only ones that had sets for my bike would've taken a month to come in.


Anyone else have issues like this getting tires? I think i'm going to start a year in advance next time.

:lol: :lol: :lol: :lol: ONLY 45 min!?!?!? I spent 3/4 of the summer tracking down tires. Count yourself lucky. although I played back order game for a month or two as well before they told me they couldn't get the tires. so your struggle may not be over.

If you have to ask if anyone else had issues getting tires, you're either incredibly stoopid or you didn't read this thread. For your sake I hope you didn't read the thread. In the future you might try actually reading the thread before asking stoopid questions.

[primal]

A Dunlop D404 was the only rear tire I could find that anyone had in stock. I was trying to replace the rear tire with another Kenda Challenger, but everyone, dealer AND online, had everything but the Dunlops on back order. To be honest, this is one of the reasons I'm looking to sell the bike, haha.

[mrlmd1]

Don't forget the 120/80 size for the front, like I said in this post on the first page when I started this whole thread. I got this Cheng Shin and it works just fine.
And it was cheaper.

With luck, you won't have to go through all the hassle some of us have had.

[Mandachan]

Actually, I DID read most of the thread.


Most of the people in this thread were talking about how hard it was to get Cheng Shin tires - I was asking about tires in general at a Suzuki Dealership, and was under the impression that Dunlops were easier to get then Cheng Shin as Cheng Shin will stop being made Janurary 2009.


This is part of the reason you don't have people ever come back, the calling stupid part. Because i DID read the entire thread before I posted. Yes, i skimmed over some posts because it's typically time consuming to read 5 pages worth of posts.

Mandachan,

The name calling is unfortunate, but I think you'll find it's just a reflection of the Internet in general. GZ250bike.com is basically open to all, except spammers, and there is no screening of uses for civility. That being said, I think you'll find, despite the occasional potshot, that this site is a sort of oasis from the flame throwing typical of forums. If you read the "comments" section after any major news site, you'll see that public discourse on the Net is not exactly erudite. Hopefully the quality of the info posted will outweigh the rudeness.

The biggest tire you can fit without doing modifications is a 140/90-15. ;) :)
