An air maintenance tire having a tire cavity and first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region, the tire further comprising: an elongate substantially annular air passageway (18, 20) enclosed within a bending region of the tire, wherein the air passageway (18, 20) is configured for operatively closing and opening segment by segment as the bending region of the tire passes through a rolling tire footprint to pump air along the air passageway (18, 20); an air inlet port assembly coupled to and in air flow communication with the air passageway (18, 20) at an inlet air passageway junction, wherein the air inlet port assembly is configured for operatively channeling inlet air from outside of the tire into the air passageway (18, 20); a pair of inlet valves (62, 64) positioned on respective opposite sides of the inlet air passageway junction in air flow communication with the inlet port assembly wherein the inlet valves (62, 64) are configured to operatively selectively open in respective opposite directions and pass a flow of the inlet air from an upstream valve side to a downstream valve side and into the air passageway (18, 20); and a pair of outlet valves (66, 68), wherein each outlet valve (66, 68) is positioned in air flow communication with a downstream side of a respective inlet valve (62, 64), and wherein the outlet valves (66, 68) are configured to operatively selectively open and conduct a flow of the inlet air from the downstream side of a respective inlet valve (62, 64) to the tire cavity; wherein the inlet port assembly comprises an air inlet portal and an air pressure regulator, wherein the air pressure regulator is configured to operatively selectively open and close the inlet valves (62, 64) responsive to an air pressure level within the tire cavity; and wherein the air pressure regulator includes control valve means operative to prohibit the flow of inlet air into the air passageway (18, 20) when the air pressure within the tire cavity is above a threshold air pressure level; characterized in that the control valve means comprises a control conduit extending between and conducting an inlet air flow between the air inlet portal and the upstream side of the inlet valves (62, 64), and in that the control valve means further comprises a control valve actuator for interrupting the inlet air flow through the control conduit to the inlet valves (62, 64) when the air pressure within the tire cavity is above the threshold air pressure level, wherein the control valve actuator is configured to move between an open position wherein air flow through the control conduit into the inlet valves (62, 64) is uninterrupted and a closed position wherein air flow through the control conduit into the inlet valves (62, 64) is interrupted, and wherein the control conduit is serially positioned between the inlet portal and the upstream sides of the inlet valves (62, 64). an elongate substantially annular air passageway (18, 20) enclosed within a bending region of the tire, wherein the air passageway (18, 20) is configured for operatively closing and opening segment by segment as the bending region of the tire passes through a rolling tire footprint to pump air along the air passageway (18, 20); an air inlet port assembly coupled to and in air flow communication with the air passageway (18, 20) at an inlet air passageway junction, wherein the air inlet port assembly is configured for operatively channeling inlet air from outside of the tire into the air passageway (18, 20); a pair of inlet valves (62, 64) positioned on respective opposite sides of the inlet air passageway junction in air flow communication with the inlet port assembly wherein the inlet valves (62, 64) are configured to operatively selectively open in respective opposite directions and pass a flow of the inlet air from an upstream valve side to a downstream valve side and into the air passageway (18, 20); and a pair of outlet valves (66, 68), wherein each outlet valve (66, 68) is positioned in air flow communication with a downstream side of a respective inlet valve (62, 64), and wherein the outlet valves (66, 68) are configured to operatively selectively open and conduct a flow of the inlet air from the downstream side of a respective inlet valve (62, 64) to the tire cavity; wherein the inlet port assembly comprises an air inlet portal and an air pressure regulator, wherein the air pressure regulator is configured to operatively selectively open and close the inlet valves (62, 64) responsive to an air pressure level within the tire cavity; and wherein the air pressure regulator includes control valve means operative to prohibit the flow of inlet air into the air passageway (18, 20) when the air pressure within the tire cavity is above a threshold air pressure level;
