Roush Mustang Spare Tire Sizes

The Roush Mustang has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2005 to 2007 along with tire diameters ranging from 26.7" to 27.3" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Roush Mustang years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
