BMW M8 Spare Tire

The BMW M8, a luxury sports car, is equipped with exceptional performance features, including the spare tire design and capability. This vehicle does not have a physical spare tire; instead, it embraces the cutting-edge run-flat tire technology, fast gaining precedence in high-performance vehicles. The run-flat tires permit the drivers to continue their journey for up to 50 miles at a reduced speed of 50 mph, even with a puncture, rendering them effectively as "spare" tires. The tire size for BMW M8 varies with the model; however, the standard size for most models is 275/35R20 front and 285/35R20 rear. These specifications apply to both the convertible and coupe versions of the M8. The exact specifications can be found in the vehicle owner's manual or the tire information placard.

BMW M8 models manufactured from 2020 to 2025 have tires with overall diameter ranging from 27.6" to 27.7", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific BMW M8 years and trims.

Listed below are compact spare tire sizes that can fit some BMW M8 vehicles based on acceptable tire diameter range of 26.8" to 28.5". Some M8 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct BMW M8 spare tire size designated by vehicle's manufacturer.
