BMW 320i Spare Tire Sizes

The BMW 320i has used 4x100mm and 5x120mm bolt pattern variations from 1977 to 2018 along with tire diameters ranging from 23.2" 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 320i years and options. In this case, 125/70R16 and 145/70R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
