How far can a car with run-flat tires go after a flat?
2 Answers
Car with run-flat tires can go approximately 250 kilometers after a flat, also known as a run-flat tire. Run-flat tires are circular elastic rubber products installed on metal rims that support the vehicle body, absorb external impacts, ensure contact with the road surface, and maintain driving performance. Precautions for using run-flat tires include: 1. Avoid speeding to prevent rubber aging, delamination, and bursting; 2. Use low-pressure tires to improve ride comfort and steering stability, preventing blowouts; 3. Regularly rotate tires to extend their service life; 4. Maintain standard tire pressure to avoid excessive wear.
I always pay special attention to driving safety. Run-flat tires theoretically allow you to drive a short distance after a blowout, generally designed for about 50 to 80 kilometers at speeds up to 80 km/h, but this is not an infinitely safe extension. The key factors are tire pressure and structural damage. Driving too long can cause the sidewall to overheat, deform, or even damage the wheel rim and suspension system. Once I detect a blowout, I immediately slow down and pull over, not daring to take risks. Regular tires can't move at all when blown, while run-flats are only for temporary emergency use—never drive too far or too fast. During routine maintenance, always check tire pressure and wear to prevent blowouts—that's the right approach. After a blowout, quickly find a professional shop to replace the tire to avoid accidents on the road.
