Abstract
An air maintenance tire assembly is provided in which an elongate groove is located within a first sidewall of a tire. The groove forms an elongate channel within the first sidewall and an elongate groove access passage extends from the elongate channel to an access opening located at an outward surface of the first sidewall. An air pumping tube inserts through the groove access passage and is positioned within the groove channel. A cover strip attaches to the first sidewall to enclose the access opening of the groove access passage. The cover strip is positioned along the first sidewall at a higher distance from the bead region of the first sidewall than the groove channel to avoid contact with a wheel rim flange when the tire is mounted to a wheel rim.
