Which Cars Can Be Equipped with Run-Flat Tires?
2 Answers
Run-flat tires must be installed on dedicated rims to prevent them from falling off the rims in a zero-pressure state. Therefore, ordinary rims cannot accommodate run-flat tires. Models like the Volvo S60 and Volkswagen R36 are equipped with run-flat tires. Currently, all BMW models come standard with run-flat tires, while other models such as the Volvo S60, Ford S-MAX, and Volkswagen R36 also feature run-flat tires. Run-flat tires, also known as self-supporting tires or extended mobility tires, work by thickening the sidewalls. Even when deflated, the thick sidewalls provide necessary support to keep the vehicle moving. If a car originally comes with standard tires, run-flat tires cannot be used. Using run-flat tires on a car not originally designed for them can cause damage to the matching chassis, suspension, and rims.
Many cars can be equipped with run-flat tires, primarily because they come with this system from the factory. I drive a BMW 3 Series, which supports these tires—allowing you to drive steadily for dozens of kilometers after a puncture without stopping. Luxury models like the Mercedes-Benz C-Class and Audi A4 often come with run-flat tires as standard, as their wheel rims and suspensions are specifically designed to match them. If you're buying a new car, check the manual or ask the dealer to ensure compatibility. Otherwise, retrofitting may require changing the rims and adding a tire pressure monitoring system, which is costly and could affect handling. For daily highway or suburban driving, run-flat tires provide real peace of mind, especially in rainy conditions where a puncture won’t lead to loss of control. The downside is that they're more expensive than regular tires, but the safety is worth the price. When choosing a car, prioritize these brands to avoid the hassle.
