BMW Bavaria Spare Tire Sizes
The BMW Bavaria has used a 5x120mm bolt pattern for all models from 1971 to 1974 along with a tire diameter of 24.7" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for BMW Bavaria spare tire selections. In this case, a 125/80R17 temporary spare tire is the recommendation for all applications.
