Why Does BMW Use Run-Flat Tires?
1 Answers
BMW uses run-flat tires primarily because they are safer and more convenient, ensuring better travel safety for car owners. According to BMW's user manual, BMW's run-flat tires can continue driving up to 80 kilometers at a speed of 80 km/h after a tire blowout, meaning there's no need to change the tire on the spot—you can drive to the nearest repair shop for replacement. Additionally, BMW's run-flat tires help improve tire handling. Moreover, run-flat tires are synonymous with high-end quality, further highlighting the sophistication of BMW owners. Here are some related details: 1. Definition of Run-Flat Tires: Run-flat tires, also known as zero-pressure tires, do not actually prevent blowouts but rather strengthen the tire sidewalls, making them less susceptible to damage when encountering sharp objects. Even after losing air, they can continue supporting the car for a certain distance. Generally, cars equipped with run-flat tires are of higher grade and more expensive, as the production cost of run-flat tires is relatively high. 2. Advantages of Using Run-Flat Tires: (1) The likelihood of losing control after a tire blowout is reduced, and the car can still travel dozens of kilometers post-blowout, enhancing safety. (2) Run-flat tires are less prone to wear and have a longer lifespan. 3. Disadvantages of Using Run-Flat Tires: (1) Cars with run-flat tires offer less ride comfort compared to those with regular tires. (2) Run-flat tires are more expensive, and their maintenance costs are also higher in the long run.
