Abstract
A closed torus tire may be inflated by means of a circumferential conduit located at the interface of the tire and a rim. The closed inflation chamber of the closed torus tire communicates with the circumferential conduit via an air inlet passageway through the annular base region of the tire's carcass. An inflation valve passageway through the rim also communicates with the circumferential conduit to provide an air conduit means for inflating the closed torus tire.
