It looks like the stock 17" wheels/tires on my 08 red Mazda3 are actually rubbing the paint off the lower inner part of the rocker panel trim pieces on both front wheels. Also looks like this is happening to a lesser degree on the lower edge of the rear fenders, too. The car has 30,000 miles and I drive several miles on bumpy dirt roads every day (at a slow speed, though). Anyone else have this problem? I've contacted Mazda and am awaiting their reply.
