BMW 328d Spare Tire Sizes

The BMW 328d has used a 5x120mm bolt pattern for all models from 2014 to 2018 along with tire diameters ranging from 25.9" to 26.0" 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 328d years and options. In this case, 165/70R17 and 145/70R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
