BMW M4 Spare Tire Sizes

The BMW M4 has used 5x112mm and 5x120mm bolt pattern variations from 2015 to 2023 along with tire diameters ranging from 26.0" to 26.9" 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 M4 years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
