I've had the same crappy wire bead Hutchinson that I've used for 2 seasons prior. It shows almost no signs of wear after initially depositing some rubber on the mag roller. It'll last through this winter without question. Slippage only happens with abrupt starts. I'll just use another old tire when that one gives up the ghost (it's a bit dry-rotted, but if it lets go on the trainer, I don't care).
