I recently purchased a new set of ZR-1 style wheels for my 1994, they are 17X9.5 on all four corners, with 56mm backspacing. My car currently has the stock 8.5/9.5 combo with 255/45 on the front, and 285/40 on the rear.
The big question... switching to the 9.5 wheel on all corners, what size front tire? I know the grand sport used a 9.5 wheel with a 275/40 on the front, but an 11 inch wheel out back. Anyone ever run this combo, and if so, what worked for tire size?
