This has nothing to do with the tires. The ride height on the front and the rear of the car is adjustable. If your tires impact the body of the car you need either stiffer springs (not the correct fix) or you need the ride height adjusted (correct fix). You could always just put 13" wheels and tires on it and eliminate the problem this way also.

The problem was created when Backdraft reduced the backspacing on the rear wheels but kept the wheel width the same, thus pushing the entire wheel outboard. Crawl underneath and you will see you have over 1 inch of clearance between the backside of the wheel/tire and the shock mount. Therefor one must run the rear of the car higher to keep the same tire to body clearance as the old 18x11 wheels had since the wheel is now much closer to the body than it was before.
