How to Distinguish Run-Flat Tires?

Run-flat tires can be distinguished by: 1. Checking the sidewall specifications, which will have special symbols that regular tires do not have; 2. Placing the tire flat on the ground and standing on it—the sidewall of a run-flat tire will be hard, while a regular tire will feel soft when pressed by hand. Run-flat tires are designed to prevent the vehicle from losing control in the event of sudden tire pressure loss. They consist 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. Characteristics of run-flat tires include: 1. They provide support and resilience, allowing the wheel rim and tire to work together to support the vehicle safely in case of sudden air loss or a blowout; 2. After a blowout, run-flat tires do not lose air immediately, enabling the driver to continue driving for a certain distance with reduced pressure; 3. Run-flat tires have reinforced sidewalls, enhancing their durability and usability.
