GMC Terrain Spare Tire

The GMC Terrain isn't equipped with a traditional spare tire. Instead, it is provided with a tire inflator kit to aid with minor tire punctures. This kit includes a portable air compressor and a sealant canister designed to temporarily repair small tire punctures, however, it is not a replacement for larger punctures or serious tire damages. Nonetheless, for those wanting a spare tire, it can be purchased separately or may be included in some specific trims. The size of the spare tire typically depends on the model year of the GMC Terrain, though in most cases a compact temporary spare tire known as a "donut", with a size of T125/70D17 is what's used. Consult your vehicle ' s manual or talk with a tire professional to verify the correct spare tire size for your specific GMC Terrain model.

GMC Terrain models manufactured from 2010 to 2025 have tires with overall diameter ranging from 28.1" to 29.2", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific GMC Terrain years and trims.

Listed below are compact spare tire sizes that can fit some GMC Terrain vehicles based on acceptable tire diameter range of 27.3" to 30.1". Some Terrain models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct GMC Terrain spare tire size designated by vehicle's manufacturer.
