BMW 650i Spare Tire Sizes

The BMW 650i has used a 5x120mm bolt pattern for all models from 2006 to 2019 along with tire diameters ranging from 26.5" to 26.8" 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 650i years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
