Saleen S121 Spare Tire Sizes

The Saleen S121 has used a 4x108mm (4 x 4.25") bolt pattern for all models from 2005 to 2005 along with a tire diameter of 24.6" 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 Saleen S121 spare tire selections. In this case, a 135/70R17 temporary spare tire is the recommendation for all applications.
