A self-inflating tire (12) is disclosed comprising a tire cavity (40), first and second sidewalls (15) extending respectively from first and second tire bead regions to a tire tread region, and air passageway (43) having a first end (42) and a second end (44) in fluid communication with the tire cavity (40). The tire (12) further comprises a regulator device (300) having a regulator body (310) having an interior chamber (320) and a pressure membrane (550) mounted on the regulator device (300) to at least partially enclose the interior chamber (320), wherein the pressure membrane (550) has a lower surface (553) that is positioned to open and close an outlet port (330) mounted in the interior chamber (320), and wherein the pressure membrane (550) is in fluid communication with tire cavity pressure. The regulator body (310) of the regulator device (300) has a first, second and third duct (350, 360, 370), wherein the first, second and third ducts (350, 360, 370) each have an internal passageway (352, 362, 372), wherein the third duct (370) has a first end in fluid communication with the outside air and a second end in fluid communication with the interior chamber (320) of the regulator device (300), wherein the first duct (350) has a first end (354) in fluid communication with the first end (42) of the first air passageway (43), and a second end in fluid communication with the interior chamber (320) of the regulator device (300), and wherein the second duct (370) has a first end in fluid communication with the second end (44) of the air passageway (43) and a second end in fluid communication with the interior chamber (320).
