Air-maintenance tire

An air-maintenance tire is disclosed having a tire carcass (12) comprising a tire cavity (30) defined by a tire inner liner, first and second sidewalls (14) extending respectively from first and second tire bead regions (16) to the tire tread region (18); compression actuator means (19) mounted to the tire carcass (12) configured for operative actuation by tire deformation during a tire revolution; and a pump assembly (20) affixed to the tire carcass (12) and comprising a compressor body affixed to the compression actuator means (19) and having an internal air chamber, the air chamber having an inlet opening for admitting air into the internal air chamber and an outlet opening for conducting air from the internal air chamber to the tire cavity (30). The air compressor body further comprises (i) a membrane valve member deforming into a deformed state within the internal air chamber responsive to actuation by the compression actuator means to compress air within the internal air chamber; or (ii) a flexible membrane member located within the internal air chamber and operatively deforming within the internal air chamber responsive to contacting engagement with the compression actuator means between an open position relative to the inlet opening wherein permitting air flow from the inlet opening into the air chamber and a closed position relative to the inlet opening wherein obstructing air flow from the inlet opening into the air chamber, wherein the membrane member during operational deformation between the open and closed positions compresses a volume of air within the air chamber. The tire (10) further comprises a hook-and-loop system (200) for securing the compression actuator means (19) and the compressor body to the tire carcass (12).
