Here is a possibility....fronts: 215/70/15 Rears: 255/70/15. That should fit. The biggest problem is in the hiney. Cop wheels are normally 4 1/4 back spacing. I have 4.5 back spacing and 275/60/15 in the rear. It's tight but no rubs. The above combo should work. Pay attention the section width of the rear tires. You should go no more than 10.5 inches with cop wheel back spacing.
