BMW 840i Spare Tire
The BMW 840i, like many of its modern day counterparts, does not come equipped with a traditional spare tire. Instead, the vehicle is designed with run-flat tires that, when punctured, can travel up to 50 miles at a reduced speed of 50 mph. This gives the driver enough time to seek professional assistance. However, for those who prefer to have an optional tire, the size required may vary depending on the specific model and year of your 840i, but a general guideline is to opt for a 17-inch spare tire. It's advisable to consult with a BMW dealership or a knowledgeable tire provider to ensure the correct size for the model.
BMW 840i 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 years and trims.
Listed below are compact spare tire sizes that can fit some BMW 840i vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some 840i 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 spare tire size designated by vehicle's manufacturer.
