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, an air pump for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, and a faceted 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 first sidewall has at least one bending region operatively bending within a rolling tire footprint and a sidewall groove defined by groove sidewalls positioned within the bending region of the first tire sidewall. The groove deforms segment by segment between a non-deformed state and a deformed, constricted state in response to the bending of the first sidewall bending region within the rolling tire footprint.
