First Tires

[bjrscj]

I know there is a lot on tires in this forum, and I've gleaned some great information. However, there are a few things I'm still unsure of and would appreciate some help.

1. I've gathered that my 2003 model has front tires of 110/90-16, and rear at 130/90-15. However, the link I followed from the forum website didn't list a year, so I'm only assuming that these tire sizes would be the same for all years. Is that correct?

2. I found a link on the forum to motorcycle superstore, which seems to be a great idea. However, as I look at the cheaper tires, I'm seeing that none of them are tubed. I haven't found more expensive brands that are tubed either. My impression from reading other posts is that the tires on the GZ are tubed, so I would assume I need tubed tires. Can anyone confirm this?

3. If I do need tubed tires, can anyone recommend a brand? I know cheap isn't necessarily good, but I got the bike to save money on gas (which it has been GREAT for), but I don't want to shell out $300 every two to three months (I rode 3k miles in the last 7 weeks since I got the bike - long commute). If you can recommend any tire that has a good trade off between value and quality, I'd appreciate it. I'd really like to use motorcycle superstore (http://www.motorcycle-superstore.com/3/ ... 0-24-1-1-1), since it would be convenient for shipping my tires to the dealer, so if you already buy your tires from there and can send a link, that would be awesome.

4. How much mileage do you expect an average rider to get out of a front/rear tire?

Thanks in advance for all your help.
