Saturn Relay Spare Tire Sizes

The Saturn Relay has used a 5x115mm bolt pattern for all models from 2005 to 2007 along with a tire diameter of 27.6" 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 Saturn Relay spare tire selections. In this case, a 145/85R18 temporary spare tire is the recommendation for all applications.
