An air maintenance tire (12) is disclosed having a tire cavity (28) defined by an inner liner (26), the inner liner (26) being bounded by first and second sidewalls (16, 18) extending to a tire tread region (24). The first sidewall (16) has an elongate sidewall air passageway (19). An outlet air passageway assembly is connected to the sidewall air passageway and directs compressed air from the sidewall air passageway into the tire cavity. A regulator assembly is positioned adjacent the tire inner liner operative to control pressurized air flow into the tire cavity. An inlet air passage screw assembly comprises an elongate screw body extending through an axial span of the first sidewall and the screw body having an elongate internal air pathway operative to conduct air through the screw body. A valve housing is located at an inward end of the screw body, the valve housing having a valve socket extending into a remote end of the valve housing in an air flow communication with the screw body internal air pathway, and the valve housing connecting at an inward end into the regulator assembly. The air passage screw assembly further comprises a valve mechanism seated within the valve socket, the valve mechanism opening to conduct air from the internal air pathway of the screw body into the regulator assembly and closing to prevent a backflow of air from the regulator assembly into the internal air pathway of the screw body.
