Saturn SC1 Spare Tire Sizes

The Saturn SC1 has used a 4x100mm bolt pattern for all models from 1993 to 2002 along with tire diameters ranging from 23.5" to 24.2" 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 Saturn SC1 years and options. In this case, 125/70R17 and 135/70R16 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
