How many kilometers can a run-flat tire travel after a puncture?

[McCollin]

According to the characteristics of run-flat tires, after a puncture, they can still maintain a speed of 80km/h, allowing you to drive for about an hour and cover a distance of nearly 80 kilometers. Here is some information about run-flat tires: Advantages of run-flat tires: In the event of a tire leak, even if the air pressure inside the tire is completely lost, you can continue driving at a speed of 80 km/h without having to replace the tire immediately. Disadvantages of run-flat tires: In terms of tire quality, due to the thicker sidewalls, run-flat tires of the same specifications are heavier than ordinary tires, which to some extent can reduce the performance of the car.

Run-flat tires, also known as zero-pressure tires, are designed to allow you to continue driving after a puncture without immediately stopping, preventing you from being stranded on the road. The standard recommendation is to drive about 50 to 80 kilometers, provided your speed does not exceed 80 km/h. From an automotive repair perspective, I know this depends on the tire brand and vehicle model—some luxury models might last longer, but don’t push your luck by driving too far. The key factor is that after losing tire pressure, the reinforced inner layer supports the weight, as long as the wheel rim isn’t severely damaged. However, once a tire blows out, avoid continuing on highways—keeping your speed between 50 to 60 km/h is safer until you reach the next service station or repair shop. Driving long distances on a flat will completely ruin the tire and may even damage the suspension, which isn’t worth the risk. Remember, this isn’t a permanent solution; timely action is crucial. Checking tire pressure during annual maintenance can reduce the chances of a blowout.

As an experienced driver, I've had a few run-flat tire blowouts, which were quite startling, but I was still able to drive to the repair shop. I remember the manual stating that theoretically, it could last for 80 kilometers, but I always kept it within 50 to 60 kilometers for safety. Maintaining a low speed is crucial, as going too fast can easily damage the wheel rims. In reality, road conditions also affect how far you can drive, such as bumpy roads shortening the distance. I would first confirm that the car isn't pulling to one side, drive to a safe area to check the tire pressure, and change the tire if necessary. If there's no service area nearby, it's better not to push it for dozens of kilometers; calling for a tow truck is more reassuring. After years of driving, the lesson I've learned is to regularly check tire wear to reduce unexpected incidents.

From a safety perspective, although run-flat tires can still be driven for a certain distance after a blowout, I do not recommend driving more than 50 kilometers or attempting extreme distances. Speeds exceeding 80 km/h pose extremely high risks, potentially leading to loss of control or wheel rim damage. After a blowout, immediately reduce speed to between 40 and 60 km/h and drive to the nearest rest area for inspection. The allowable distance depends on load and tire type—full loads increase tire stress and shorten the drivable range. Once air leakage begins, the tire can last at most a few hours before stopping is necessary. Driving safety comes first; don't take shortcuts by driving too far. It's advisable to install a tire pressure monitoring system for early warnings, significantly reducing the chances of a blowout.
