2015 BMW 640i Spare Tire
The BMW 640i model, typically fitted with run-flat tires, does not typically come with a spare tire. Run-flat tires are designed to resist the effects of deflation when punctured, allowing the driver to continue to drive at reduced speeds for limited distances, often eliminating the need for a spare tire. However, if a driver prefers having a spare tire, they would need to purchase it separately. The spare tire size for BMW 640i can vary, but generally, a compact temporary spare tire would be size T135/80R17. This spare tire type, designed to get you to a nearby garage should your tire become damaged, is not meant for long-term or high-speed use. It's important to note that the BMW 640i is not equipped with a dedicated spare tire storage space, so accommodations will need to be made for storing it in the vehicle.
