  "textContent": "An air maintenance tire (12) comprising a tire cavity (26), first and second sidewalls extending from first and second tire bead regions, respectively, to a tire tread region; and an elongate, preferably substantially annular air passageway (20) enclosed within a bending region of the sidewalls is disclosed. The air passageway (20) operatively closes and opens, segment by segment, as the bending region of the sidewalls passes adjacent a rolling tire footprint to pump air along the air passageway (20). The tire (12) further comprises an air inlet port assembly (28) coupled to the air passageway (20) at an inlet air passageway junction, the air inlet port assembly (28) being operable to channel inlet air from outside of the tire (12) into the air passageway (20), the air inlet port assembly (28) including an inlet control valve (601) and an outlet tee structure (612) preferably positioned 180° opposite the inlet control valve (601) in the air passageway (20) for moving air into the tire cavity (26), the inlet control valve (601) including two inlet check valves (62, 64) for ensuring air flow only into, and not out of, the inlet control valve (601), the air passageway (20) and the tire cavity (26). Also, method for pumping air into a tire cavity (26) of a tire (12) is disclosed.",
