I'm looking to put beefier tires on my Specialized Crosstrail hybrid, which currently has 700x35c wheels/tires. I'm curious if a 29"x1.8" tire will fit without issue. I'm 215 lbs and need a little more cushion than the 700x35's provide when hopping curbs, etc. and a bit better traction during light off-roading. If I can't get a beefier tire on there, then I will likely sell the bike (see classifieds section).
