Abstract:
1. A pneumatic tire assembly comprising: a tire having a pneumatic cavity; a filter element disposed between the pneumatic cavity and atmosphere, the filter element being constructed of a porous plastic, the filter element having threads for securing the filter element to the pneumatic tire; first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region, the first sidewall having at least one bending region operatively bending when radially within a rolling tire footprint; and a sidewall groove defined by groove walls positioned within the bending region of the first tire sidewall, the sidewall groove deforming segment by segment between a non-deformed state and a deformed, constricted state 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 segment by segment between an expanded condition and an at least partially collapsed condition in response to respective segment by segment deformation of the sidewall groove when radially within the rolling tire footprint.
