Been there... done that. I jsut got a 1994 F150 wiht the aluminum rims. I am not proficient on sharp turns yet, and I cut one too sharp. THe front got to the curb and up on it. I got home, was about to go in, and I decided to chekc it out. Damn near tore out the WHOLE sidewall and got into the rim a bit (not enuf that I couldnt smooth and buff it out). I got lucky I made it home. Had to get that one replaced. Was a new tire too... damn it.
