Saturn Astra Spare Tire Sizes

The Saturn Astra has used a 5x110mm bolt pattern for all models from 2008 to 2009 along with tire diameters ranging from 24.9" to 25.6" 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 the specific Saturn Astra years and options. In this case, a 125/70R18 temporary spare tire is the recommendation for all applications.
