<P>PROBLEM TO BE SOLVED: To provide a tire assembly incorporating an self-inflation function. <P>SOLUTION: An air passageway body 46 within a tire body extends between an outward facing tire body surface and a tire cavity 30, and has an enclosed air passageway extending between a hollow body outlet end 54 facing the tire cavity 30 and a hollow inlet end 52 facing outward from the outward facing tire body surface. A tapping device is affixed to cover the ends of the air passageway body 46, and has an external vent opening and a protrusion member. The protrusion member penetrates through a sidewall of the air passageway body 46 to form an air flow path extending between the air passageway of the air passageway body 46 penetrating through the protrusion member and the tapping device vent opening. The air passageway body 46 is installed pre-cure within a green tire carcass and the tapping devices are attached post-cure to the air passageway body 46. <P>COPYRIGHT: (C)2012,JPO&INPIT |
