BMW 545i Spare Tire Sizes

The BMW 545i has used a 5x120mm bolt pattern for all models from 2004 to 2005 along with tire diameters ranging from 25.6" 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 545i years and options. In this case, a 155/70R17 temporary spare tire is the recommendation for all applications.
