How far can a BMW run-flat tire go after losing air?

[DeTalia]

BMW run-flat tires can still run 80 kilometers after losing air. Relevant introductions are as follows: 1. In the case of tire deflation, the vehicle can still travel 80 kilometers at a speed of 80 km/h; If the driver has no experience in driving after a flat tire, he may make wrong driving actions (such as emergency braking), which will lead to uncontrollable loss of control of the vehicle; 2. Flat tire is a very serious safety accident, especially on the highway. According to statistics, 70% of accidental traffic accidents on domestic highways are caused by flat tires, and the mortality rate of flat tires at speeds above 160 km/h is close to 100%; 3. Equipping the vehicle with "run-flat tires" solves the safety problem to the greatest extent. The real "run-flat tires" are military 6×6, 8×6 and other tire off-road armored vehicles. Their tires are designed with special metal strips, which can keep the tires from deformation even if they are penetrated by artillery shells and continue to move forward.

Last time I was driving my BMW, the tire suddenly went flat, and I didn't realize it until I had driven quite a distance. BMW's run-flat tire design is quite amazing—it allows you to continue driving for about 80 kilometers even when the tire is flat, but you shouldn't exceed 80 km/h, or the sidewall of the tire might get damaged faster. I didn't notice the tire pressure warning light at the time, so I only stopped at a safe spot after driving for a while. If you encounter this situation, be sure to slow down immediately, turn on the hazard lights, and find the nearest repair shop. Don't delay—even though you can drive 80 km, uneven roads or high-speed driving can shorten this distance, and the inner wall wear can double the cost of replacing the tire later. In short, safety comes first, and timely action is the most cost-effective.

As someone who frequently tinkers with cars, I must say BMW's run-flat tires are indeed practical. They feature reinforced internal support structures that can bear the vehicle's weight even when deflated, allowing you to drive slowly for about 50-150 kilometers depending on the model and tire condition, though BMW's manual recommends 80 kilometers as the upper limit. Speed should be kept below 80 km/h to prevent heat buildup from accelerating tire failure. I recommend keeping a small tire pressure gauge in the car for regular checks; if a puncture occurs, drive slowly to a professional repair shop. While the extended driving range is an advantage, the lifespan of a repaired run-flat tire is halved, so early repair ensures peace of mind. Regular monthly tire inspections during routine maintenance can save you from major troubles.

After driving BMWs for a while, I've encountered the tire pressure warning twice. Run-flat tires can still go quite a distance when leaking, roughly 80 kilometers is no problem as long as you don't speed. Last time I slowly drove to the repair shop, taking over 70 kilometers to get it fixed. The key is to watch for the dashboard warning light and slow down immediately if you notice abnormal vibrations. Don't follow those who recklessly keep driving, as that can easily damage the rims. My experience suggests trying to find a repair shop within 50 kilometers to avoid roadside emergencies. Never take tires lightly - regular inspections are crucial.
