BMW 640i xDrive Spare Tire

The BMW 640i xDrive, part of BMW's 6 series, does not typically come with a spare tire as standard equipment, reflecting a trend in many luxury vehicles. Instead, it often comes equipped with run-flat tires that, in case of a puncture, can be driven on for up to 50 miles at a reduced speed, giving the driver enough time and distance to get to a service station or tire repair shop. The original tire size for a BMW 640i xDrive is generally 245/40R19 for the front and 275/35R19 for the rear. If the vehicle owner wishes to purchase a spare tire, a compact spare tire (or "donut") can be purchased that fits the vehicle's wheel dimensions. Always be sure to verify the tire sizes with the vehicle's manual or a professional before making a purchase.

BMW 640i xDrive models manufactured from 2014 to 2018 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 640i xDrive years and trims.

Listed below are compact spare tire sizes that can fit some BMW 640i xDrive vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some 640i 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 640i xDrive spare tire size designated by vehicle's manufacturer.
