Pontiac Grand Prix Spare Tire Fitment Guide

The Pontiac Grand Prix used 5x115 mm and 5x4.75" (5x120.7 mm) bolt pattern variations from 1978 to 2008 along with tire diameters ranging from 25.3" to 27.2" 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 Pontiac Grand Prix years and options. In this case, 125/80R18, 145/80R17, 145/60R20 and 135/80R18 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 Pontiac Grand Prix spare tire.
