BMW 540i Spare Tire Sizes

The BMW 540i has used 5x112mm and 5x120mm bolt pattern variations from 1994 to 2021 along with tire diameters ranging from 25.0" to 26.8" 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 540i years and options. In this case, 125/80R17, 155/70R17, 135/70R18 and 145/60R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
