Abstract
A groove defined by groove sidewalls is positioned within the bending region of a tire sidewall. An elongate air tube positioned within the sidewall groove is in contacting engagement with the groove sidewalls and resiliently squeezes and collapses segment by segment as the groove constricts segment by segment within the rolling tire footprint. A longitudinally oriented projecting locking rib extends from a tube sidewall and registers within a complementary configured and located detent extending adjacent the groove to deter lateral movement of the tube within the groove after insertion. An annular projecting ridge extends from the groove for engaging the sidewalls of the air tube to deter an axial movement of the tube within the groove after insertion.
