GMC Terrain Spare Tire Fitment Guide
The GMC Terrain used 5x115 mm and 5x120 mm bolt pattern variations from 2010 to 2026 along with tire diameters ranging from 28.1" to 29.3" tall. Using a temporary compact 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.
The tire diameter and the wheel diameter clearance have been taken into account for the specific GMC Terrain years and options. In this case, 155/85R18 and 155/90R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct GMC Terrain spare tire.
