BMW 8 Series Spare Tire Fitment Guide
The BMW 8 Series used 5x112 mm and 5x120 mm bolt pattern variations from 1990 to 2026 along with tire diameters ranging from 25.3" to 27.9" 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 BMW 8 Series years and options. In this case, 125/80R17, 145/60R20 and 145/65R20 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 BMW 8 Series spare tire.
