Hummer H3T Spare Tire Sizes

The Hummer H3T has used a 6x5.5" bolt pattern for all models from 2009 to 2010 along with tire diameters ranging from 31.6" to 32.8" 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 Hummer H3T years and options. In this case, using a non-temporary Full-Size tire as your spare, is the recommendation for all applications.
