Abstract
A pneumatic tire and wheel assembly of the drop center type is disclosed including an inflatable annular cord-reinforced tube for filling the well of the wheel. The uninflated diameter of the cord-reinforced annular tube is substantially equal to the diameter of the base of the wheel well but expands to a diameter greater than the diameter of the bead seats upon inflation. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawings and the following detailed description.
