Abstract
An air maintenance tire system and method in accordance with the present invention includes an air pumping mechanism configured to maintain air pressure within a first tire and a second tire in a dual tire arrangement. The system includes a control valve assembly attached to an elongate valve stem projecting from a rim of a first tandem tire, and a one-way valve carrying connecting tube from a sidewall air pumping passageway within a sidewall of the first tire. The control valve assembly further includes first and second outlet tubes connected to the elongate valve stem to selectively pass pressurized air into the tire cavities of both tandem mounted tires on an as-needed basis.
