BMW M850i xDrive Gran Coupe Spare Tire
The BMW M850i xDrive Gran Coupe does not come with a standard spare tire, often due to the vehicle's performance-focused design and reduced unnecessary weight. However, it utilizes run-flat tires that allow drivers to continue driving for up to 50 miles at a speed of 50mph even when the tire is punctured - subsequently eliminating the immediate need for a spare tire. These run-flat tires are of the same size as the regular tires, which in the case of the BMW M850i xDrive Gran Coupe are 245/35R20 in the front and 275/30R20 at the rear. Nevertheless, if a driver feels the need to have spare tire readily available, it's advisable to ask specifically for an optional compact spare tire of matching size from the dealership or an authorized auto parts store.
BMW M850i xDrive Gran Coupe models manufactured from 2020 to 2025 have tires with overall diameter ranging from 26.7" to 26.8", 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 M850i xDrive Gran Coupe years and trims.
Listed below are compact spare tire sizes that can fit some BMW M850i xDrive Gran Coupe vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some M850i xDrive Gran Coupe 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 M850i xDrive Gran Coupe spare tire size designated by vehicle's manufacturer.
