Tire Size
The 255's fit all the way around. The front though rub when turning sharp such as into a parking space. When I replace them I will put either 215, 225 or 235's in front. The BF Goodrich's are excellent tires in my opinion.
Polishing the Wheels
These are the stock wheels for and 86-88 SS. To polish them I first sanded of the clear coat off with 80 grit sand paper, then I sanded the scratches out with 400. After that I used Aluminum polish. For the paint I just used regular wax. It took me about 3 hours each. In the pictures you can tell which one I polished.
