GMC Sierra 1500HD Spare Tire Sizes

The GMC Sierra 1500HD has used a 8x6.5" bolt pattern for all models from 2002 to 2007 along with a tire diameter of 30.5" 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 GMC Sierra 1500HD spare tire selections. In this case, using a non-temporary Full-Size tire as your spare, is the recommendation for all applications.
