How to Repair a Run-Flat Tire?
1 Answers
Run-flat tire repair methods include: 1. Plugging with rubber strips; 2. Cold patching, commonly known as the patch method; 3. Mushroom plug repair, also called rubber nail; 4. Hot vulcanization. If the tire tread is punctured with a nail hole larger than 6mm in diameter, it is not recommended to repair, and the tire should be replaced. Run-flat tires, technically known as "puncture-proof tires," are composed of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator, a pressure sensor, and a control unit. The principle of run-flat tires is to ensure that the tire can maintain functionality even when it loses air pressure. The thickened rubber sidewalls can support the vehicle's weight without causing severe deformation, so a punctured run-flat tire will not significantly affect the vehicle's driving performance, and the driver may not even notice the issue.
