The invention relates to a self-inflating tire and a pressure regulator. Specifically, a self-inflating tire assembly includes an air tube connected to a tire and defining an air passageway, the air tube being composed of a flexible material operative to allow an air tube segment opposite a tire footprint to flatten, closing the passageway, and resiliently unflatten into an original configuration. The air tube is sequentially flattened by the tire footprint in a direction opposite to a tire direction of rotation to pump air along the passageway to a inlet control valve. The inlet control valve regulates the inlet air flow to the air tube and the outlet air flow to the tire cavity.
