자가 팽창 타이어 조립체는 타이어 측벽 그루브내에 장착된 공기 튜브를 포함한다. 공기 튜브는 공기 튜브를 둘러싸는 대향 각진 그루브 표면과 접촉 맞물림되어 있다. 공기 튜브의 세그먼트는 튜브 공기 통로를 따라 평탄화된 세그먼트로부터 배기된 공기를 강제하도록 롤링 타이어 풋프린트내의 그루브의 굽힘 및 압축에 의해 팽창된 직경으로부터 평탄한 직경으로 평탄화된다. 측벽 그루브는 림과 비접촉 관계로 위치된 타이어 체이퍼 돌출부의 축방향으로 배향된 표면과 같은 환형의 축방향으로 연장되는 측벽 표면내로 연장된다.

    A self-inflating pneumatic tire has a cavity (40), first and second sidewalls (30, 32) extending respectively from first and second tire bead regions (34, 36) to a tire tread region (38). The first sidewall (30) has at least one bending region (196, 198) operatively bending within a rolling tire footprint (100) responsive to a bending strain whereby the bending region (196, 198) in a bending condition within the rolling tire footprint (100) having a bending strain neutral axis (180), a compression side (182) on one side of the neutral axis (180) and an elongation side (184) on the other side of the neutral axis (180). A sidewall groove (126) is positioned within the compression side (182) of the bending region (196, 198) of the first tire sidewall (30). An air tube (42) is positioned within the sidewall groove (126) in contacting engagement with opposite groove surfaces (128, 130) at least partially surrounding the air tube (42), the sidewall groove (126) operatively bending within the bending region (196, 198) responsive to a bending strain within the rolling tire footprint (100) to compress the air tube (42) from an expanded diameter to a flat diameter adjacent the rolling tire footprint (100) whereby forcing evacuated air from a flattened air tube segment (102) along an air passageway (43).
