Claim:
1. An air maintenance assembly for dual-mounted tires comprising: a first tire and second tire mounted in a side-by-side dual relationship mounted to an axle, the first and the second tires each mounted respectively to a first rim and a second rim and each of the first and the second tires having a tire cavity bounded by first and second sidewalls extending to a tire tread region; a control valve assembly including a control valve housing having an internal air passageway, the control valve housing being coupled to a valve stem and being external to the tire cavity of each of the first and second tires, the first sidewall of the first tire having an elongate sidewall air passageway therein operatively located to compress segment-by-segment from an expanded diameter to a substantially reduced diameter responsive to a bending strain introduced into the first sidewall from a rolling tire footprint thereby forcing air, segment-by-segment, along the air passageway; a connecting tube connected to the elongate sidewall air passageway and to the control valve housing, the connecting tube operative to direct pressurized air into the control valve housing internal air passageway as the tire rolls over a ground surface; and wherein the control valve housing is in fluid communication with first and second outlet tubes having internal air passageways operable to conduct pressurized air into the first tire cavity and the second tire cavity on an as-needed basis.
