An air maintenance assembly for dual- mounted tires, the assembly comprising: a first tire and second tire (12, 14) mounted in a side-by-side dual relationship to an axle, the first and the second tire (12, 14) being each mounted respectively to a first rim and a second rim (13, 15) and each of the first and the second tires (12, 14) having a tire cavity (22, 24) bounded by first and second sidewalls (18, 20) 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 attached to an elongate valve stem projecting from the rim of the first tire, the control valve housing being external to the tire cavity, the elongate valve stem projecting outward from a control valve housing cavity and being operative to direct pressurized air into the internal air passageway and into the tire cavity of the first tire and into the tire cavity of the second tire, 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; characterized in that said air maintenance assembly comprises further a connecting tube connected to the air passageway and to the control valve housing, the connecting tube being operative to direct pressurized air into the control valve housing internal air passageway as the tire rolls over a ground surface; wherein the control valve housing has first and second outlet tubes (62, 64) having internal air passageways operable to selectively conduct pressurized air into the first tire cavity and into the second tire cavity on an as-needed basis. a first tire and second tire (12, 14) mounted in a side-by-side dual relationship to an axle, the first and the second tire (12, 14) being each mounted respectively to a first rim and a second rim (13, 15) and each of the first and the second tires (12, 14) having a tire cavity (22, 24) bounded by first and second sidewalls (18, 20) 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 attached to an elongate valve stem projecting from the rim of the first tire, the control valve housing being external to the tire cavity, the elongate valve stem projecting outward from a control valve housing cavity and being operative to direct pressurized air into the internal air passageway and into the tire cavity of the first tire and into the tire cavity of the second tire, 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; characterized in that said air maintenance assembly comprises further a connecting tube connected to the air passageway and to the control valve housing, the connecting tube being operative to direct pressurized air into the control valve housing internal air passageway as the tire rolls over a ground surface; wherein the control valve housing has first and second outlet tubes (62, 64) having internal air passageways operable to selectively conduct pressurized air into the first tire cavity and into the second tire cavity on an as-needed basis.
