OK, fine, I've done a quick search on smooth or treadless tires. All I can find is tha they are a good idea. Even Jobst Brandt and his ilk did not say where to order some. Vredestein, Performance, Kenda and others; nada in the 700 x 32 and up size range. I had a friend say he and others shaved the bumps off of several sets of tires for a RAAM racer. Pass. Any suggestions?
