Pontiac G8 Spare Tires
The Pontiac G8 used a 5x120 mm bolt pattern for all models from 2008 to 2009 along with a tire diameter of 26.7" 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 Pontiac G8 spare tire selections. In this case, a 145/80R17 temporary spare tire is the recommendation for all applications. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Pontiac G8 spare tire.
