if the right weight is put on when u take them off it doesnt hurt them that much...ive polished out the scratches they make on my rims in the past and they come from the factory that way...the front tires are original and the weights were never taken off of the rims...car was always serviced at the dealership i work at and i pulled service history on it and all it ever had done were oil changes and no warranty repairs ever on it...30,000 on the car
