i bent my stock 16 inch rim on a pothole! i took the opportunity to order the 18s i wanted but ill be more careful now. im still waiting on them to come in. but no matter how careful you are, its still hard to avoid them. discount tire offeres a warrenty on all their tires so if something happens, they will replace it. im not sure if it goes for the rims or not but since the tires support the rims, they should replace it. ill be sure to get that when i get my new wheels.
