When I bought my stang the previous owner had on a set of chrome 18's on it. It wasnt until after I bought the stang that I realized all of the chrome on the inner side of the wheels is chipping and peeling off. My assumption is that the previous owner of my stang used these wheels in the winter time (I live in michigan, crappy salty roads 5 months of the year. So is it normal, I guess so if you dont take care of your wheels.
