GMC Envoy Spare Tire Sizes

The GMC Envoy has used a 6x127mm (6 x 5") bolt pattern for all models from 2002 to 2009 along with tire diameters ranging from 29.5" to 29.6" 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 GMC Envoy years and options. In this case, 155/90R18 and 165/90R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
