BMW 528i Spare Tire Sizes

The BMW 528i has used a 5x120mm bolt pattern for all models from 1979 to 2016 along with tire diameters ranging from 24.7" 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 528i years and options. In this case, 125/70R18, 145/60R20 and 165/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
