BMW Z4 Spare Tire Fitment Guide
The BMW Z4 used 5x112 mm and 5x120 mm bolt pattern variations from 2003 to 2026 along with tire diameters ranging from 24.9" to 26.7" 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 Z4 years and options. In this case, 125/80R17, 125/80R18 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 BMW Z4 spare tire.
