When an ordinary tire loses tire pressure, the tire will instantly break away from the wheel hub and only rely on the wheel hub to contact the ground. The biggest difference between run-flat tires and general tires is that they have very tough and supportive sidewalls.
Such a design can help the tire in the event of a puncture or sudden deflation, and ensure that the tire and the wheel hub can be combined and give a certain support to the vehicle, thereby ensuring the safety of the vehicle.
From its design, we can see that because its sidewall is relatively thick, and some tough substances are added during production, which also makes the wear resistance of the run-flat tire better, so its service life will theoretically be Longer than normal tires.
But even if you are using a run-flat tire, you must replace it according to the wear indicator on the tire. If the wear indicator does not reach the limit of use for more than four years, replace it because the tire rubber will follow It ages over time and creates danger.
