Pontiac Bonneville Spare Tire Fitment Guide

The Pontiac Bonneville used 5x115 mm and 5x4.75" (5x120.7 mm) bolt pattern variations from 1982 to 2005 along with tire diameters ranging from 25.3" to 27.3" 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 Pontiac Bonneville years and options. In this case, 125/80R18, 135/80R18 and 145/60R20 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 Bonneville spare tire.
