FITTING BIGGER TIRES ON A FOXBODY
Adding bigger tires to a Fox Body Mustang is a very popular subject for 1979-1993 Mustang owners. Most Fox owners who mod their cars want a wider tire in the rear, but sometimes it is not that easy. Coming from the factory with 15" and 16" wheels and tires, everyone was quickly finding out what works and what doesn't when adding aftermarket wheel and tire kits. Most stock Fox Body Mustangs can not accommodate a wheel and tire larger than 245/50/17 without any modification of the fenders, control arms, or quad shocks. Instead of searching around for tire size calculators, this all in one guide will help you find the perfect tire size on your Fox.
To clear bigger tires in the rear, fender rolling is one of the best ways to get more clearance. Fender rolling on your Mustang folds in the inner fender lip to prevent cutting on the tire. Be sure to use a heat gun when rolling the fenders to prevent a chance of flaking the paint.
Another solution for the Fox Body Mustang is replacing the stock control arms. With the strength and design of aftermarket control arms, there is no longer need for the quad shocks. The compact design of tubular control arms also takes up less space in the wheel well, allowing better tire clearance all around.
If your car is equipped with quad-shocks, often flipping them around, in addition to rolling the fender, will allow you to squeeze a larger tire out back. Some people go as far as removing the quad shock completely, but this isn't ideal as the quad shock is there to counteract the wheel hop allowed by the flimsy stock control arms during hard acceleration.
