The tire had been on/off the rim a couple times because I had improperly put the tube in and had to patch a couple small tears, but nothing that would've gone through the sidewall. The tires on the bike were 700-23c and I was running 700-20c.
Could be a manufacturing defect. This happened once to me with an almost-new Panaracer Urbanmax tire (a model that I regard very highly otherwise). There was clearly a weak spot in the fabric around where the tube blew through and tore off the bead.
If this appears to be the case, I'd ask for a replacement. Performance Bike was good about replacing mine.
