Cool. Just looking at the Mountain Equipment Coop site, noticing they list a few sizes that fit, and that specifically seem geared to convert moutain bikes to roll better on the roads.

Thanks for the info, I'm much more equiped now I think. I'll probably look local for a bit, and if not order from MEC. Is there any advantage to certain tires? I notice some support a PSI similar to what I have now, 35-65. One tire on the site supports up to 95 psi. Wondering if there is an advantage there to rolling resistance or not.
Seem pretty cheap upgrading as well which is nice. If I really got into it, I'd probably get a road bike, but for now, 50 bucks on tires sounds pretty good.

Thanks, much appreciated. Any suggestions on a good website with bike info? I'd like to find one that gives maitenance details, since I have never really tuned the bike. It seems to run fine, but there is probably stuff I should be doing to it.
