Why Did Mercedes-Benz Discontinue Run-Flat Tires?
2 Answers
Mercedes-Benz discontinued run-flat tires due to their high noise levels and poor comfort. Here are some details about run-flat tires: 1. Disadvantages: Run-flat tires are relatively stiff, so they can feel more jarring when driving over bumpy roads. Additionally, run-flat tires of the same grade are slightly more expensive than regular tires. 2. Performance: After a blowout, run-flat tires allow the car to continue driving at up to 80 km/h for approximately 80 kilometers, which is sufficient to reach the nearest repair shop for a tire replacement. Therefore, Mercedes-Benz vehicles do not need to carry a spare tire. 3. Functionality: Run-flat tires not only enable continued driving after a loss of pressure but also enhance safety. In the event of a blowout, run-flat tires do not immediately collapse because their sidewalls are exceptionally thick, providing strong support to prevent the vehicle from rolling over. Furthermore, vehicles equipped with run-flat tires do not require a spare tire, allowing continued driving without immediate tire replacement, offering convenience and additional trunk space.
From my driving experience, Mercedes-Benz phased out run-flat tires mainly to improve driving comfort. The sidewalls of run-flat tires are too stiff, resulting in strong vibrations while driving, especially on bumpy roads where it can literally give you backaches. Mercedes engineers probably figured that conventional tires paired with a tire repair kit or temporary spare tire are more cost-effective; after all, run-flat tires are extremely heavy, increase fuel consumption, and negatively impact vehicle handling. After the removal, the car rides smoother and quieter, making long-distance driving less tiring. Moreover, run-flat tires are troublesome to repair—once damaged, they can only be replaced, and the prices are outrageously expensive. Switching to standard tires makes repairs simpler and more economical. I feel this reflects Mercedes-Benz's emphasis on user experience, turning driving into an enjoyment rather than a torment.
