GMC Sierra K2500 Spare Tire Sizes

The GMC Sierra K2500 has used 6x5.5" and 8x6.5" bolt pattern variations from 1988 to 1998 along with tire diameters ranging from 29.3" to 31.6" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for the specific GMC Sierra K2500 years and options. In this case, using a non-temporary Full-Size tire as your spare, is the recommendation for all applications.
