I have a stock 1992 with I believe 275x40xR17 all around. I believe 17 x 9.5 rims. I just bought some black zr1 18 x 9.5 rims all around for the car, as the stock rims are shot. What size tires should I purchase. The Black On Black with Black Rims may be too much but we will see. Any help would be greatly appreciated.
