Buick Park Avenue Spare Tire Fitment Guide

The Buick Park Avenue used a 5x115 mm bolt pattern for all models from 1985 to 2005 along with tire diameters ranging from 26.0" 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 Buick Park Avenue years and options. In this case, 125/80R18, 145/80R17 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 Buick Park Avenue spare tire.
