Abstract
An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, air pumping means for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, the air pumping means including a soft tubing and compression fittings for mitigating dynamic loading on the compression fittings, and a valve housing disposed adjacent an outward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity. The valve housing is connected to the air pumping means by the soft tubing and compression fittings for mitigating dynamic loading on the compression fittings.
