I bought some tires at Performance (retail store) recently-- cheap kevlar-belted Michelin 700s, 23c. I installed 'em on my early 90s road frame and found that the front tire was not completely round! Every rotation would make a little scrape as the lump passed the fork's arch...not cool. I'd previously had rather fat Specialized Armadillo 23c tires on the same bike with no clearance problems (though it was a close fit). And I'm positive the tube wasn't pinched or damaged, and the bead was securely on the rim. Wheel was centered in the dropouts just fine.
I didn't think anything of it-- just explained it to the clerk and returned the tire. No questions asked. (bought a $30 Continental instead...)
But now a friend tells me that Performance sells "b-stock" factory second tires, and this same problem is commonplace. Is this true? Anyone else have a similar experience?
