BMW 840i xDrive Spare Tire

The BMW 840i xDrive, a high-performance luxury coupe, does not come with a standard spare tire due to its focus on weight-saving and overall performance efficiencies. Instead, it is equipped with run-flat tires designed to be driven for a certain distance even after a puncture happens. This allows drivers to reach the nearest garage or service center without the need for a spare tire swap on the side of the road. The tire type and size for the BMW 840i xDrive typically comes in at 245/45R19 (front) and 275/40R19 (rear), but may vary slightly depending on the specific model year. Additionally, while the 840i xDrive does not include a spare tire as standard, BMW does offer compact temporary spare tires as an accessory for those who desire the extra security, although they should be used only for short-distance emergency use.

BMW 840i xDrive 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 xDrive years and trims.

Listed below are compact spare tire sizes that can fit some BMW 840i xDrive vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some 840i xDrive models may require the use of a traditional full-size tire as a spare.
