    Abstract: An enclosing means for lubricant for use in a pneumatic tire and wheel assembly to be located on or adjacent the interior surface of at least one lower sidewall region of the tire. The means comprises a closed annular pocket, at least one radially extending portion of a wall of which is constructed to be under greater stress than the remaining portions when the pocket is filled with lubricant and located in the tire. The greater stressed portion is located nearest to the interior surfaces of the tire when in use to urge the pocket towards the interior surface of the tire against counteracting centrifugal forces which tend to urge the pocket away from the surface. Also included is a tire and wheel assembly.
