BMW 325i Spare Tire Sizes

The BMW 325i has used 4x100mm and 5x120mm bolt pattern variations from 1987 to 2006 along with tire diameters ranging from 24.0" to 25.0" 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 325i years and options. In this case, 125/70R17 and 125/80R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
