BMW 850csi Spare Tire Sizes
The BMW 850csi has used a 5x120mm bolt pattern for all models from 1994 to 1997 along with a tire diameter of 25.3" 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 850csi spare tire selections. In this case, a 125/80R17 temporary spare tire is the recommendation for all applications.
