摘要

PROBLEM TO BE SOLVED: To maintain a desired level of air pressure within a tire without the need for driver intervention.SOLUTION: An air pumping tube, tire system and method of assembly is provided in which a tire groove is formed to extend into a flexing region of a tire sidewall and an air pumping tube is inserted into the tire groove. In an unvulcanized, uncured condition, one or more check valves are assembled in the air pumping tube through access shafts and along with an internal air passageway 28 of the air pumping tube. Plug components 78 of the system enclose the check valves in the air pumping tube, and the check valves contained in the unvulcanized air pumping tube are then cured.
