Abstract
Official abstract text for this publication.
An air maintenance tire includes an air inlet housing affixed to the inner liner of a tire. An elongate sidewall air pumping passageway is incorporated within a first tire sidewall. An elongate air tube is contained within the first sidewall and has an elongate elliptical internal air passageway. The air tube is configured having a substantially on-side mushroom-shaped sectional shape extending radially into the first tire sidewall formed by a radially inward tube cap and a radially outward tube stem. Inlet and intake conduits connect into sockets of the inlet housing and a pressure regulating valve system within the inlet housing controls pressurized air flow from the tube internal air passageway into the tire cavity.
