BMW Alpina B8 Spare Tire Sizes
The BMW Alpina B8 has used a 5x112mm bolt pattern for all models from 2022 to 2023 along with tire diameters ranging from 27.6" to 27.8" 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 Alpina B8 years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
