I would remove the rear tire and check with my fingers. You can feel the thickness off-center and estimate how thick the rubber is in the middle. If you do this to a new tire, you'll get an idea of how much you've worn. Off the top of my head, the checkerboard file tread is gone in the first third of my JB's lifespan. It goes for a while after that. Others have offered salient advice on sidewall deterioration and increasing number of flats (from shards, rather than big honkin' pieces o' glass). - Jim -- Jim Edgar cyclofi...@earthlink.net Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Gallery updates now appear here - http://cyclofiend.blogspot.com "That which is overdesigned, too highly specific, anticipates outcome; the anticipation of outcome guarantees, if not failure, the absence of grace."
