Saab 9-7x Spare Tire Sizes

The Saab 9-7x has used a 6x127mm (6 x 5") bolt pattern for all models from 2005 to 2009 along with tire diameters ranging from 29.0" to 30.0" 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 Saab 9-7x years and options. In this case, 155/90R18 and 175/70R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
