Went down to 29 in the front and that seems to have made it a little stickier. Now if I can just push it a little farther and spend about 3 hard days on the sides they won't be square! All I do is ride to work and back, to church and back, and to work and back. Doesn't make for very well rounded tires. Shoot, I'd be happy with a 1/4" chicken strip even, I don't even have to have them all the way... but city riding is a little slick most of the time it seems.
