I am about to purchase new wheels and tires for my 67 coupe. The car had 16 x 8's when I bought the car, but I have decided to go back to 15's. I am considering a 15 x8 for the front and 15 x 10 (if possible) for the rear. Are these sizes possible? Also what size tires can I fit under the fender wells safely but without rubbing. I like the looks of a full fender well. But I do not want to rub! Thanks for all your help.
