An air maintenance tire 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), the air passageway (19) being located to operatively to compress segment by segment from an expanded diameter to a substantially reduced diameter responsive to a bending strain introduced into the first sidewall (16) from a rolling tire footprint to compress air along the sidewall air passageway (19). A regulator assembly (30) is positioned adjacent the tire inner liner (26) operative to control pressurized air flow into the tire cavity (28). An inlet air passageway assembly (36) connects to the first sidewall (16) and is operative to conduct air from outside the tire (12) into the regulator assembly (30). An outlet screw assembly (74) comprises an elongate screw body extending through an axial span of the first sidewall (16). The elongate screw body has an elongate internal air pathway (108) operative to conduct air from the sidewall air passageway (19) to the tire cavity (28). The screw body has at least one outwardly projecting arm (96, 98) at a radially outward end, the projecting arm (96, 98) fitting within the sidewall air passageway (19) and having an axial arm air passageway (100) operative to conduct compressed air from the sidewall air passageway (19) to the screw body internal air pathway (108).
