Last week, when stopping at a store, I accidentally hit the curb with my passenger side front tire. The wheel actually climbed up the curb, but then slipped down and the car continued moving about a foot. When it slipped down, the tire's side wall and the rim scratched against the curb. The rim has only a barely visible scratch on the edge, not a big deal. However, the tire shed some rubber. There is a small hole, about 1/3 inch deep and 1/2 inch wide. Should I be worried about it? Should it be more likely to rupture or lose air? I have been checking tire pressure but it hasn't changed.
