A tire and pump assembly is disclosed. The assembly comprises a tire having a tire cavity, first and second sidewalls extending from first and second tire bead regions, respectively, to a tire tread region; an elongate preferably substantially annular air passageway enclosed within a bending region of at least one of the sidewalls, the air passageway operatively closing and opening, segment by segment, as the bending region of the sidewall passes adjacent a rolling tire footprint to pump air along the air passageway; an air inlet port assembly coupled to, and in air flow communication with, the air passageway at an inlet air passageway junction, the air inlet port assembly being operable to channel inlet air from outside of the tire into the air passageway; a pair of substantially inline valves positioned on respective opposite sides of the inlet air passageway junction in air flow communication with the inlet port assembly, the inline valves selectively opening in respective opposite directions and passing a flow of the inlet air from an upstream valve side to a downstream valve side and into the air passageway; a pair of outlet valves, each outlet valve positioned in air flow communication with a downstream side of a respective inline valve, the valves selectively conducting a flow of the inlet air from the downstream side of a respective inline valve to the tire cavity; and a shut-off valve for preventing an over-inflation condition in the tire cavity.
