  "textContent": "An air maintenance tire (12) is disclosed comprising a tire cavity (28) bounded by first and second sidewalls (18) extending to a tire tread region (26); air pumping means (14) for generating pressurized air for maintaining air pressure within the tire cavity (28) at a preset pressure level, the air pumping means comprising a soft or elastic tubing (30, 80, 101, 102) and one or more compression fittings (320); and a valve housing (110) disposed adjacent an outward end of a valve stem (80), wherein the valve housing is operative to selectively open and close pressurized air flow from an internal passageway of the valve stem (80) into the tire cavity (28), the valve housing (110) being connected to the air pumping means (14) by the soft or elastic tubing (30, 80, 101, 102) and the compression fittings (320) for mitigating a dynamic loading on the compression fittings (320). The first sidewall (18) comprises at least one bending region operatively bending within a rolling tire footprint and a sidewall groove or passageway (32) positioned within the bending region of the first tire sidewall (18), the sidewall groove or passageway (32) deforming segment by segment between a non-deformed state and a deformed, constricted state in response to the bending of the first sidewall (18) bending region within the rolling tire footprint.",
