What Does Run-Flat Tire Mean?
1 Answers
Run-flat tire refers to a type of tire designed to prevent blowouts, also known as a self-supporting tire, and is marked with RSC on the sidewall. Structurally, run-flat tires are not significantly different from regular tires, except for the reinforced design on the sidewall. The technical name for run-flat tires is "self-sealing tire," typically 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 function of run-flat tires is not to allow the driver to continue driving after a problem occurs but primarily to prevent the vehicle from losing control in the event of sudden tire pressure loss. It is crucial to drive to the nearest place where the tire can be inflated as soon as possible—the closer, the better. Prolonged driving under such conditions can easily lead to the failure of components such as the tire, wheel hub, ball joint, and lower control arm.
