BMW 840i Gran Coupe Spare Tire

The BMW 840i Gran Coupe does not come equipped with a traditional spare tire due to its sports-oriented design which prioritizes weight-saving and performance capabilities. Instead, it utilizes run-flat tires that can be driven on temporarily after they lose air pressure. These tires allow the vehicle to be driven at reduced speeds (up to 50 mph) for distances of up to 50 miles in case of a puncture, without posing significant handling or safety risks. However, for those that wish for a traditional spare for long-distance travel or peace of mind, the standard tire size for the 840i Gran Coupe is 245/40R20 in the front and 275/35R20 in the rear which can be purchased as an extra.

BMW 840i 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 840i Gran Coupe years and trims.

Listed below are compact spare tire sizes that can fit some BMW 840i Gran Coupe vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some 840i 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 840i Gran Coupe spare tire size designated by vehicle's manufacturer.
