BMW Z4 Spare Tire Sizes

The BMW Z4 has used 5x112mm and 5x120mm bolt pattern variations from 2003 to 2021 along with tire diameters ranging from 24.9" to 26.7" tall. Using a temporary 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. Tire diameter as well as wheel diameter clearance have been taken into account for the specific BMW Z4 years and options. In this case, 125/80R17, 125/70R18, 145/60R20 and 145/70R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
