biggest tire size
I measured the backspacing for my wheels. The front wheels 18" X 8" are 5 3/8" backspacing.... The rear wheels 18" X 9.5 are 6 1/4" backspacing.... I moved the rear springs in with a .80" off set hanger to make room for the wide wheels and tires, also I centred the rear axle housing to the car for proper fitment. The wheels and tires are the widest that can fit in the stock well. I have just 3/16" clearance betweent the tire side wall to the quarter panel lip and 3/16" from the side wall to the leaf spring. It works well, only because of the low profile design of the tire. You will need a strong side wall or it will rub. Hop this helps you. Let me know what you do.
