Abstract
A pneumatic tire assembly includes a tire, a filter element disposed between a pneumatic cavity and atmosphere. The filter element has threads for securing to the pneumatic tire. First and second sidewalls extend respectively from first and second tire bead regions to a tire tread region. The first sidewall has a bending region operatively bending when radially within a rolling tire footprint. A sidewall groove defines groove walls positioned within the bending region of the first tire sidewall. The sidewall groove deforms in response to bending of the bending region of the first sidewall while radially within the rolling tire footprint. An air passageway is defined by the sidewall groove and deforms when radially within the rolling tire footprint.
