How far can a BMW drive after a flat tire?
2 Answers
If equipped with run-flat tires, the vehicle can still drive up to 250 kilometers after a flat tire. Causes of flat tires: Speeding, overloading, tire wear and aging, excessive or insufficient air pressure, poor tire quality, impact, tire sidewall bulging, or manufacturing defects in the tire. Why run-flat tires can continue driving: In the event of a tire leak, even if the air pressure inside the tire is completely lost, the vehicle can still continue driving at speeds up to 80 km/h without immediately needing to replace the tire. The reason run-flat tires do not collapse after losing air pressure is mainly due to their reinforced rubber sidewalls. Even without air pressure, the sidewalls can support the vehicle's weight without causing severe deformation, so a flat tire does not significantly affect the vehicle's driving performance.
I personally experienced a tire blowout once while driving a BMW, and it was truly terrifying. After a blowout, you absolutely must not drive too far because the wheel rim will directly contact the road surface, causing severe wear. Especially at high speeds, the vehicle can easily lose control, which is extremely dangerous. Many BMW models come equipped with run-flat tires, commonly known as Run-Flat tires, which allow you to drive at low speeds for about 80 kilometers after a blowout, enabling you to reach a repair shop. However, in practical terms, I recommend keeping the speed below 50 km/h and ensuring the road conditions are good. If a blowout happens on the highway, immediately turn on the hazard lights and pull over to the side. Waiting for assistance or changing to a spare tire is the safest option. Make it a habit to regularly check your tires—measure the tire pressure once a month to avoid other faults caused by driving on damaged tires. Safety first—don’t gamble with your life over small savings!
