BMW 525i Spare Tire Sizes

The BMW 525i has used a 5x120mm bolt pattern for all models from 1989 to 2007 along with tire diameters ranging from 25.3" to 25.9" 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 525i years and options. In this case, 125/80R17 and 165/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
