Self-inflating tires are a type of tire designed to automatically maintain optimal air pressure. They use a built-in system that detects when the tire pressure drops and inflates the tire as needed. This technology helps improve safety, fuel efficiency, and tire longevity by ensuring that tires are always at the correct pressure. These tires typically incorporate a small compressor and sensors that monitor pressure levels. When the pressure falls below a certain threshold, the system activates to add air. This innovation can be particularly beneficial for vehicles like cars, trucks, and bicycles, reducing the need for manual inflation.
