2020 BMW M240i Spare Tire
The BMW M240i, like many modern vehicles, does not come with a traditional full-size spare tire due to constraints regarding weight, fuel efficiency, and storage. Instead, BMW equips this model with run-flat tires, designed to resist the effects of deflation when punctured, allowing the driver to continue to drive at a reduced speed - under 50 mph (80 km/h) - for limited miles before the tire needs to be replaced. However, if a driver prefers to have a spare tire for emergencies, BMW provides an optional compact spare (also known as a "donut" or space-saver tire), generally in tire size T125/80D17. This smaller, temporary solution is intended only for short-distance use and should be replaced with a regular tire as soon as possible.
2020 BMW M240i comes with 1 OEM tire size option. 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 2020 BMW M240i spare tire size.
