I hit a fist-sized rock/chunk of dirt on the freeway last weekend, which made a part of the tire bulge out on the sidewall (but much closer to the thread than to the wheel). The bump is ~1" across and sticks out ~1/8-1/4" (don't have a camera handy). The tire pressure seems fine.
Should I be running to get a new tire -- am I cheating death by seriously risking a blow-out every time I get behind the wheel? Or can I live with it for a few months? A friend told me she's done the latter in the past...
These are the stock Suby Potenza tires that everyone bitches about. Yes, I'm going to replace them sometime soon, but wasn't planning on it just yet.
