A self-inflating tire with air passageway to allow a portion of the air passageway near a tire footprint to open and close. An inlet regulator device is connected to an inlet end of the air passageway and includes an insert having a bore therethrough having a first end located in the tire cavity and a second end which extends through the tire. A pressure membrane (64) is received within the first end of the insert. A regulator body (154) is received within the second end of the insert. The regulator body (154) has an interior passageway extending from a first end to a distal end extending into a cavity (158) of the insert. The pressure membrane (64) is responsive to a cavity tire pressure and an outside air pressure and is engageable with the distal end of the regulator body (154) when the tire pressure reaches a set value for opening and closing the inlet regulator device to allow or prevent air flow from entering the inlet regulator device.
