Good tires...i put 2000 miles+ on a set of 700x28 wire-bead since last summer...i had my rear suffer one flat during that, but had to replace it this year since unwillingly being forced into a "rumble strip" by an idiotic, uncaring motorist on her cellphone, the dividing "safety" line that separated the road from the bike lane in a local town (shepherdstown, wv, if anyone reading is familiar.) That rumble-strip is hardcore roughness at 18MPH and put my wellworn gatorskin into its final coffin...but in the past 2 weeks, i had my LBS hook me up with a 700x28 Gator Hardshell, which is about 70grams heavier than the ultra it replaced, but much more suitable for my rear wheel....time will tell how much better it wears than the regular gatorskin, but i must say, i can't tell the difference in weight, and i feel a little more secure if i ever am unfortunate enough to be put into the situation of the severe vibration of another road-related inconvenience like that...the front gatorskin i put on last summer is still looking good...btw i currently weigh 220lbs on a 30lb Trek hybrid...IMHO, Continental has got a good balance of lightweight and ruggedness for a commuter/training tire with the gatorskin/hardshell...and they ARE smoooooth riding with 95-100lbs PSI in them , too

I've had mine up to 110psi, but ride was a little too harsh...i always worry about puncture resistance from gravel and glass with pressure that high, plus the rear-wheel problems i was having when i was 260lbs+, but thats' another story
