Put a new tube in on the trail yesterday and got it up to about 70 PSI before riding back. Today I pumped it up to 120 and I was about a mile out, wondering why the bike was handling strange, when all of a sudden I felt my back wheel starting to rub against the brakes on one spot, then I hear a loud bang. Not sure if it was a pinched tube or what but it came out and popped and left part of the tire over the rim. I managed to put another tube in and get back but I am wondering is the tire still usable or is it possible it got damaged when the tube blew? The tire is a 700x23 Gatorskin with only ~100 miles on it.
On a side note, a sympathetic passer-by allayed some of my frustration by offering me some beer he was lugging back.
I'd guess the rim tape too. My Cannondale had crappy plastic rim tape that shifted from mounting tight-fitting tires. I had what sounded like a blowout but the bead had popped over the rim in about a 2-inch section.
Replace with cloth rim tape. The tire should be fine. But verify that the bead and sidewall are good.
