What is the difference between run-flat tires and regular tires?
2 Answers
The differences between run-flat tires and regular tires are: 1. Different materials: Run-flat tires mainly add a thick layer of natural rubber with anti-solidification function and nano-renewable technology on the sidewall of the tire; regular tires are constructed from raw materials such as natural rubber and renewable energy rubber. 2. Different wear resistance: When a tire experiences a blowout, run-flat tires can continue to drive normally for a certain distance; regular tires cannot drive normally after losing air. Run-flat tires are also called air-maintaining tires, and the tire sidewall will have an RSC mark. There is no particularly big difference in structure between run-flat tires and regular tires, except that the sidewall of the tire is reinforced, which allows the tire to continue supporting the car in the event of air leakage or sudden loss of pressure.
The difference between run-flat tires and regular tires is quite significant, and I value the safety improvements the most. Run-flat tires can continue to drive for a certain distance after a puncture or blowout by relying on reinforced sidewalls, sometimes up to about 50 kilometers, without having to stop immediately on the roadside. This is particularly useful on highways or in remote areas. Regular tires, once they blow out, go completely flat, potentially causing the vehicle to lose control, and require immediate towing or spare tire replacement. I once experienced the benefits of run-flat tires on the highway, allowing me to drive slowly to a repair shop, while a friend with regular tires was forced to stop and wait. However, run-flat tires are generally more expensive, and maintenance requires professional equipment, whereas regular tires are much cheaper and more convenient for daily tire changes. Overall, run-flat tires are more suitable for scenarios prioritizing safety and frequent long-distance driving.
