How Long Can a Run-Flat Tire Be Driven After a Blowout?

[JuliaDella]

Run-flat tires can be driven approximately 80 kilometers after a blowout. More details are as follows: 1. Compared to regular tires, their greatest advantage is the ability to prevent vehicle loss of control in case of tire deflation, ensuring the vehicle can continue to operate normally and maintain stable driving at speeds not exceeding 80 km/h for up to 80 km. 2. This range is sufficient to drive the vehicle to the nearest repair shop or service station. It's important to note that installing run-flat tires does not prevent blowouts but enhances driving safety when a blowout occurs. 3. More remarkably, even if all the air is lost, run-flat tires can still safely drive to a repair shop. With zero tire pressure, the vehicle can continue to drive at 80 km/h for up to 150 kilometers. Owners can confidently eliminate the need for a spare tire, thereby reducing load and fuel consumption. 4. The design principle of run-flat tires relies on sturdy sidewalls to provide support. Another design approach involves installing a device called a fixed ring inside the tire, which supports the tire from the inside, preventing it from being crushed and also stopping the tire from detaching from the tire bead.
