Flat Rear Tire

[SWASHBUCKLER]

We recently punctured our rear tire and tried to get it plugged only to find out it is a tube tire. Having plugged the tire we are unsure if we should replace both tire and tube to be on the safe side. We can't figure out what size tube it takes because many of the tube sizes listed are not the metric size which we need. Tire is a 130/90-15 so what standard size tube would work and where is the best place to get tires and tubes?

The tire should have a vulcanized patch on the inside of the tire.Many 15 inch tubes will fit different width 15 inch tires as the tube expands to fill the tire. :rawk: :)

Contact your local store or http://www.bikebandit.com/ is a good place. A slightly bigger tube will be okay as well. Last fall I bought two tires and tubes from them. These are tubeless tires but on GZ you need a tube and tubes go with tubeless without a trouble. The tires are good. Just to clarify that the front tire is expensive than the rear. I did not understand this.

When the wheel has spokes, the tire has a tube. :)

If it was a small, clean puncture, in the tread and NOT the sidewall.....then a plug and a new tube should be all that's required.

If you took a BIG object, such that it made a big, uneven hole......OR the puncture was in the side-wall or the very edge of the tread....then you probably need tube AND a new tire.

spoke rims are usually tubeless, but the rebel 450 had tubeless rims. the rim was one piece with the spokes hooking to the rim, and the nipples were in the hub.

No,The other way around.Rims with spokes usually have tubes unless it is like the rebel that you speak of,or the wheel is cast.

36 spokes hooked into a rim means you have 36 places to leak air if no tube is used. Cast wheels usually are equiped with tubless tires but there are a few exceptions. If you have tubless tires on spoked wheels there is probably a tube inside. There are no ill effects running a tube in a tubeless tire.

The spokes hook to the outside of the rim,leaving the rim one piece for tubeless tires.A lot of the MOTO GUZZI came with the same concept.
Also the valve stem hole on a tubeless tire is larger to accommodate the valve stem.

BMW has made some models like that, although I don't think any of them are current. I could be wrong about the second statement.

They are still used somewhat,but if you get a bent wheel they are very hard to get true again as they cannot be straightened the same as a conventional spoked wheel.

Gotta disagree with you on the valve stem hole size. Vtrom came tubeless and later had a tube installed. No problems encountered with fit. Now back to tubeless, no problems.

About 3 weeks ago in the local shop a fellow was picking up a slightly bent GS1200 rear wheel. It could not be trued due to it's size and construction. A complete rear wheel price tag would be a heart stopper.

Gotta disagree with you on the valve stem hole size.

And you would be wrong. Sorry. :)

The stem hole usually is larger for a tubless rim to accomodate the larger "pop in" stem that must seal the hole and hold pressure.

The smaller stem of a tube fits in there just fine, however, and there is some reinforcement around the base of the stem that prevents it from bulging out. Sometimes there is even a ring you screw on the outside to firm it up even more.

The smaller stem hole on a tube type rim should give you pause if you try to put a tubeless tire on it.......and the stem won't fit in the smaller hole. Alas, some folks are so dense that they drill out the hole to MAKE it fit. :roll:

Easy, did you find this out from personal experience ? :lol:

:plus1: I have seen people doing this and sealing spoke nipples trying to convert to tubeless. :roll: :rawk:

Easy, did you find this out from personal experience ? :lol:

Right past the point of realizing that the stem wasn't going to fit........and going back to the shop to ask if they had a smaller one......... :roll:

The good news is that nobody ELSE was in the shop at the time. :cry:

That is funny but worth the experience. I'm sure the shop guys knew you would be back.

That's because you put a tube (with a small valve stem) into a hole (large diameter) designed for a tubeless valve. Try putting a tubeless valve (large diameter) into a tube hole (small diameter) & you'll see that it works one way, but not the other. :tdown:

Alright already! You win, I admit to having a senior moment. :lol:
