Can Run-Flat Tires Still Be Driven When Flat?

[GabrielMarie]

Run-flat tires can still be driven when flat. Relevant information is as follows: 1. Driving: Even if the air pressure in the tire is completely lost, you can still continue driving at a speed of 80 km/h without immediately replacing the tire. 2. Driving Distance: Run-flat tires can still travel up to 250 kilometers after a puncture. In reality, if encountering significant damage (such as being punctured by a large sharp object) or poor road conditions, the driving distance may be reduced to several tens of kilometers, typically within the range of around 100 kilometers. The reason run-flat tires do not collapse after losing air is mainly due to their thickened rubber sidewalls. Even without air pressure, the sidewalls can support the vehicle's weight, preventing severe deformation. Therefore, a punctured run-flat tire does not significantly affect the vehicle's driving, and the driver might not even notice it.
