Does BMW have a spare tire?
2 Answers
BMW older 5 Series models have a spare tire, located under the floor in the trunk. New models do not have one. The reason why the new BMW models do not come with a spare tire is because they use run-flat tires. The advantage of run-flat tires is that they enhance driving feel and handling. The classifications of spare tires are as follows: 1. Full-size spare tire: A full-size spare tire has the exact same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. 2. Compact spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, so it can only be used as a temporary replacement and should only be used on non-driving wheels. Additionally, the maximum speed should not exceed 80 km/h. 3. Run-flat tire: Also known as a safety tire (run-flat tire), commonly referred to as a "run-flat tire," the industry directly translates it as "tire that can run when flat." Compared to regular tires, run-flat tires do not lose air or lose air very slowly when punctured, maintaining the driving profile, and the tire bead remains fixed on the rim, ensuring the car can drive for a long time or temporarily to a service station.
I've been driving BMWs for many years and noticed that most BMW models indeed don't come with a spare tire, especially the mainstream models in recent years. This is a signature design feature of BMW, using run-flat tires that can keep going for about 50-80 kilometers after a puncture, enough to reach the nearest repair shop. The benefits are obvious: slightly lighter body weight, better fuel efficiency and agility, plus extra trunk space for luggage. However, there are drawbacks to note - run-flat tires are expensive, and if they're truly damaged, you'll need to replace them immediately, unlike a spare tire which can save money in emergencies. I recommend checking tire pressure before driving to ensure safety. BMW provides an emergency toolkit including an air pump and sealant, allowing you to handle minor leaks yourself. Overall, this design is quite reliable, but don't forget regular maintenance.
