A self-inflating tire 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 a pump passageway (43) having an inlet end (42) and an outlet end (44) is disclosed. The outlet end (44) is in fluid communication with the tire cavity (44). The tire (12) further comprises (i) a flow bridge (100) having an internal passageway (106), the internal passageway (106) having a first end (102) and a second end (104); a first flow tee (108) having an internal duct (120) and having an outlet in fluid communication with the first end (102) of the flow bridge (100), said internal duct (120) having in inlet in fluid communication with the outside air; and a second flow tee (110) having an internal duct (122) and having an inlet in fluid communication with the second end (104) of the flow bridge (100), said internal duct (120) having an outlet in fluid communication with the inlet end (42) of the pump passageway (43); and/or (ii) a regulator device (300) having a regulator body or central housing (310) having an interior chamber (320); a pressure membrane (550) mounted on the regulator device (300), wherein the pressure membrane (550) has a lower surface (553) that is positioned to open and close an outlet port (330), wherein the pressure membrane (550) is in fluid communication with tire cavity pressure, wherein the regulator body or central housing (310) has a first duct (400) and second, duct (500), wherein said ducts (400, 500) each have an internal passageway (404, 504), wherein the first duct (400) has a first end connected to an inlet filter assembly and a second end (406) connected to the interior chamber (320) of the regulator device (300), and wherein the second duct (500) has a first end connected to the outlet port (330) of the regulator device (300) and a second end in fluid communication with the inlet end (42) of the pump passageway (43).
