Abstract: A method of constructing a self-inflating tire assembly includes molding in an air tube-receiving groove within a green tire carcass wall, the groove having an access opening, primary internal groove chamber and a secondary expansion groove chamber adjacent to and communicating with the internal groove chamber. A groove partial passageway is molded with the groove at a prescribed groove outlet location and extends from the groove partially through the tire carcass wall toward the tire cavity. A tire carcass wall barrier of reduced section between the partial passageway and the tire cavity is removed in a post-cure operation to create a through-bore from the groove to the tire cavity. A pump assembly inserts into the tube-receiving groove in a post-cure procedure with an outlet passage tube from a pump assembly outlet device extended through the through-bore to the tire cavity.

Abstract: A tire assembly includes a tire carcass body and an air tube body extending between an outward facing tire body surface and an inward tire body surface. The air tube body has an enclosed hollow enclosed outlet end at a first end and an enclosed hollow inlet end at an opposite second end. An air passageway extends through the air tube body from the inlet end to the outlet end. The outlet end is positioned to face exposed from the outward tire body surface and the inlet end is positioned to face exposed from the inward tire body surface. The air tube body is integrally formed of resilient flexible material composition and includes a hollow outer casing and one or more hollow air cables positioned within the casing for regulating the rate of air flow from the inlet end to the outlet end.
