Audi A8 Spare Tire Fitment Guide
The Audi A8 used a 5x112 mm bolt pattern for all models from 1995 to 2026 along with tire diameters ranging from 26.6" to 28.6" 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 Audi A8 years and options. In this case, 145/80R17, 145/65R20, 155/85R18 and 145/80R19 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 Audi A8 spare tire.
