I just got new tires on my '05 coupe. I got them at the dealer. When they removed the old balancing weights from the rims, it left a black, rubbery smudge where the old weights were. Maybe some type of adhesive. I don't know. Before I go through the hassle of taking it back to the dealer, does anyone know of a quick and easy way this stuff can be removed without damaging the wheels?? It looks a mess....
