Let me start by saying it has been a LOOOONNNGGG time since I've ridden a bike, but I'm trying to get back into it to hopefully shed a few pounds and spend time with friends while doing it! And this site is AWESOME!

I just acquired a 2010 Trek Valencia (FOR FREE!!). It is still rolling on the stock wheels and tires, which are Bontrager Race Lite Hard Case tires on Bontrager Satellite Nebula rims. The tires are in descent shape, but I would like to get something with a little more tread. I was also wondering if I could go any wider than 32mm with the current rims? Could I get away with 35mm or even 40mm tires? As I said before, I'm a bigger guy so more rubber touching the ground would make me feel better and I'm not overly concerned with super low rolling resistance as I don't plan on doing a long ride for a while.

Any help is greatly appreciated!
