Do Run-Flat Tires Have Inner Tubes?
1 Answers
Run-flat tires do have inner tubes, and their construction is fundamentally similar to that of regular tires. Below are specific details about run-flat tires: 1. Run-flat tires, also known as extended mobility tires, differ most significantly from regular tires in that their sidewalls are extremely thick. When inflated, the sidewalls of run-flat tires serve as the primary support for the vehicle's weight. 2. Run-flat tires 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. Run-flat tires are marked with special symbols following the specifications on the tire sidewall, which are absent on regular tires.
