So I was getting into my car the other day and noticed a bubble/bump the size of a quarter (and protruding about a quarter of an inch from) on the sidewall of my front left tire. I'm guessing I got this from hitting a pothole or something, of which there are no shortage of in Washington DC, where I live. I'm wondering if anybody knows if this can/could be replaced under warranty? I doubt it, as I didn't purchase any extended warranties of any kind, and I called two of my local dealerships and they both said its not covered, but I just wanted to ask around to see if anybody else has any experience with this...my car is under 6000 miles and I've had it since June.
