Ford Mustang Wheel Fitment - One Size Does Not Fit All

This Autoworks project car has an even larger 18-inch wheel on the rear axle. The company specializes in custom wheels and tires and their fitment to classic Fords. While the trend has been to go larger, the number of fitment hurdles grows with every increment of increase. Because this '67 Mustang convertible is in primer, it's hard to tell that the rear fenders have been carefully flared to accommodate the larger wheel and tire assembly.

On applications where you have no choice on offset, the difference can sometimes be compensated for using a spacer set. That is how these late-model Mustang GT five-spoke wheels fit this early car. They would look great on almost any classic Ford.

On this 20-inch installation, clearances are closer still. As the body rolls during cornering, the inner sidewalls on the rear tires will rub if the wheelhouse is not massaged. This car is destined for the show circuit. You can use the following table to point you in the right direction for sizing. Fitting a wheel and tire package is different for each vehicle, but staying within these guidelines will enhance your chances for a good and workable fit. Use the dimensions of your existing wheel and tire package as a reference to determine the dimensions of the new wheel/tire package.

To fit the late-model Mustang GT wheels onto the early car, a spacer kit like this one can be used. It is available from several sources and is a simple solution that works well.

Make sure a qualified professional mounts your tires. It's easy to both damage a tire and get hurt with a tire machine if you don't know exactly what you're doing. We had Pit Crew Tire Service's mobile tire center come out to mount our Nitto NT555 tires on the Classic Creations project car. Pit Crew's high-end Hunter TC3500 tire-mounting machine installs tires easily without touching the rim. Once the tire is seated, it will be inflated with nitrogen for minimal leakdown and optimum tire life.
