"Created by engineers at Coda Development in the Czech Republic, the system involves the use of a small cavity in the tire wall and an inexpensive “managing valve.” When a vehicle’s tires are rolling, the valve in the Self-Inflating Tire transfers air into the cavity, which in turn delivers it to the tire. The managing valve, which rotates along with the tire, refills on every revolution. Whenever the tire’s pressure is lower than the air pressure inside the tiny cavity, the system opens its intake and delivers air. When the pressure in the cavity and the tire are equalized, the system’s intake is disabled, and refilling ceases."
