This spring as I was slobbering on and wanting to ride my good bike, I noticed that the rear tire has shown what I think is a lot of wear. There is actually a flat surface on the contact surface of the tire. The tires were brand new last fall on a brand new bike that only got about 700 miles last fall. I would say that 60-70% of my riding is on asphalt, and the rest would be chip and seal and other marginal paved surfaces.
the tires are continental gp 3000s, size 23, and I always make sure they are to 120lbs before I ride, b/c I weigh 235 and don't want any flats (still got one though).
after this I checked my SS tires and the rear hadsimilar wear on a 23 michelin megamium. but the ss is not a good comparison b/c I frequently ride it with my work crap and man purse items which surely total 30+ lbs sometimes. and on rougher surfaces....

also: is this site slow on anyone else's computer? I look at pictures all the time, movies, all that good stuff, and it never tires out my computer like bikeforums.
