When I was commuting by bike, I had to ride on roads and bike paths that were often broken or had frost heaves. Riding a bike with my weight and carrying at least a small load made using fatter tires a necessity if I wanted to prevent damage to my rims. These days there are relatively fattires that are pretty light and fast, as well as very puncture resistant. I am currently riding Conti Sport Contact and Vittoria Hyper tires in 700x37c. If you areunder 200 lbs, 700x32c is probably more than big enough, if your bike has room for them. Those fast weekend rides are the place for the fast, hard, light tires.
