GMC Safari Spare Tire Sizes

The GMC Safari has used 5x127mm (5 x 5") and 6x5.5" bolt pattern variations from 1985 to 2005 along with tire diameters ranging from 26.6" to 27.9" 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 GMC Safari years and options. In this case, 145/60R20, 145/85R18, 165/70R17 and 155/65R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
