2025 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.
2025 BMW 840i Gran Coupe comes with 2 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact BMW dealership to confirm the correct 2025 BMW 840i Gran Coupe spare tire size.
