I don't get peoples problems with tires on rainers either. I've been running a set of Bontragers 700 x 38's on my bike for two years now, no trouble with it on the trainer. I don't spend nearly the time Will seems to (I average an hour a day, duringthe winter) and haven't run into trouble. I was in my LBS and talked with one of the guys there, they started carrying the continental trainer tire last year. He said he'd sold a couple, but hadn't had any personal experience with them. After reading 998's comment on the sticky yellow powder i'm reluctant to put one on. I'm surprised that there have been no positive comments on them.
