To provide an air pressure maintenance tire-pump assembly.
A groove formed from a groove sidewall is positioned within a bent region of a sidewall. An elongate air tube positioned within the groove is in contacting engagement with the groove sidewall and elastically crushed for each segment as shrunk for each segment within a tire footprint where the groove is rotated. Locking ribs turned in a longitudinal direction and projected extend from a tube sidewall, and the these ribs are assigned within a detent configured complementarily with the ribs and disposed while extending adjacently to the groove so as to deter the lateral movement of the tube within the groove after insertion of the tube. An annular projected ridge extends from the groove and is engaged with the sidewall of the air tube to deter the axial movement of the tube within the groove after insertion of the tube.
