How long can a run-flat tire run after a blowout?
2 Answers
After a blowout, you can continue driving for 50-80 kilometers at a speed below 80 km/h without air pressure. The following measures should be taken after a run-flat tire blowout: Do not brake suddenly; instead, slow down gradually. While slowing down, keep both hands firmly on the steering wheel. Turn in the opposite direction of the blowout to ensure the vehicle continues in a straight line. Methods to prevent tire blowouts: Choose radial tires; use low-pressure tires whenever possible; pay attention to whether the speed matches the tire's load capacity during normal driving; maintain standard tire pressure, and avoid pouring cold water to reduce pressure when the tire pressure increases due to high temperatures.
I've been driving for over ten years and have encountered several blowouts with run-flat tires. Each time, I was able to continue driving for a certain distance. Generally, you can drive a maximum of 50 to 80 kilometers, and the speed should not exceed 80 kilometers per hour, otherwise the tire may overheat and become very dangerous. The last time I had a blowout on the highway, I slowed down to around 70 kilometers per hour and drove over 60 kilometers to the repair shop. The sidewalls of the tire are thick enough to support the weight of the car, but the driving experience was very shaky, and the noise was as loud as driving on a gravel road. It's recommended to immediately slow down and turn on the hazard lights after a blowout, then find the nearest parking lot or repair shop to stop. A damaged tire will heat up and deform, and driving too far may cause a fire or loss of control. Regular maintenance should include checking tire pressure and wear to reduce the risk of blowouts. I make it a habit to change tires regularly to avoid problems on long trips. The key point is that this design is for emergencies, so don't take advantage of it for extended driving. The mechanic told me during repairs that after driving on a blown-out tire, it's basically ruined and needs to be replaced.
