These Tires Inflate Themselves
The idea is deceptively simple. The tire has an air tube built into the sidewall, next to the bead. As the wheel turns while on the road, it works on the tube like a roller pump, continuously pumping air into the tire through a one-way valve. A "managing valve" in the tire lets air pressure out as needed to maintain perfect pressure at all times. If you need more air in the tire for hauling heavier loads, the valve can be adjusted to a higher level. Driving a couple miles will pump the tires up.
