A self-inflating tire assembly is disclosed comprising a tire having a tire cavity, first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region and further comprising a first air tube defining an air passageway, the first air tube being composed of a flexible material operative to allow a portion of the air tube segment near a tire footprint to close the passageway, the first air tube having an inlet and an outlet; and a second air tube defining an air passageway, the second air tube being composed of a flexible material operative to allow a portion of the air tube segment near a tire footprint to close the passageway, the second air tube having an inlet and an outlet. The inlet of the first air tube is in fluid communication with the inlet of the second air tube. The outlet of the first air tube and the second air tube is in fluid communication with the tire cavity. Instead of a first and second air tube, a first and second air passageway integrally formed in the tire may be used.
