2018 BMW M3 Spare Tire
The BMW M3, like most high-performance vehicles, traditionally did not come with a spare tire originally, to save space and weight. Instead, many models are outfitted with run-flat tires or have a tire repair kit. However, for those who prefer to have a spare tire on hand, the recommended spare tire size is 18 inches, which is designed to fit the M3's large brake setup. The usual spare tire type is a compact, also referred to as a "donut", which is a smaller-than-standard wheel meant for temporary use to get the car to a repair shop, but full-size spare tires that match the other tires on the vehicle are also an option for those who desire additional assurance.
2018 BMW M3 comes with 3 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 2018 BMW M3 spare tire size.
