How long can run-flat tires last after a blowout?

[DelColeman]

The so-called run-flat tires are actually air-maintaining tires. After a blowout, they can continue to run for 50-80 kilometers at a speed below 80 km/h without air pressure, ensuring you can reach a tire shop for replacement or repair. The following measures should be taken after a run-flat tire blowout: 1. Do not brake suddenly; instead, slow down gradually; 2. While slowing down, hold the steering wheel firmly with both hands; 3. Steer in the opposite direction of the blowout to maintain the vehicle's straight-line movement. Additional tips for preventing blowouts: 1. Choose radial tires; 2. Use low-pressure tires whenever possible; 3. Pay attention to whether your driving speed matches the tire's load capacity; 4. Maintain standard tire pressure—avoid using cold water to reduce pressure when tires are hot, as high temperatures increase internal pressure.
