BMW M550i xDrive Spare Tire

The BMW M550i xDrive doesn't come equipped with a conventional spare tire. Instead, it utilizes run-flat tires which allow the driver to continue driving for a limited distance at a reduced speed after a puncture or loss of pressure, negating the immediate need of a spare tire. These tires have reinforced sidewalls that support the vehicle's weight during a loss of air pressure. The standard tire size for the M550i xDrive is 245/40R19 front and 275/35R19 rear. It should be noted that the tire size can change based on the model year and optional equipment installed. The use of run-flat tires smoothens the overall driving experience by eliminating the inconvenience of having to instantly replace the tire during driving, and also saving space in the vehicle that would otherwise be occupied by a spare tire. It ' s always important, however, to periodically check the condition of the tires and get them replaced if necessary, to ensure safety and enhanced vehicle performance.

BMW M550i xDrive models manufactured from 2018 to 2023 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 M550i xDrive years and trims.

Listed below are compact spare tire sizes that can fit some BMW M550i xDrive vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some M550i xDrive 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 M550i xDrive spare tire size designated by vehicle's manufacturer.
