Abstract: A non-vulcanized tire body in the form of an endless band has opposite edges, an inner surface, and an outer surface having a tread. Either a completely enclosed toroidal shaped inner tube formed of non-vulcanized material or a layer of non-vulcanized material having a high impermeability to air is positioned on the inner surface of the tire body. The tire body is then wrapped around the inner tube, and the opposite edges of the tire body are joined to form a completely enclosed tire. The edges may be abutted or overlapped. Thereafter, the tire is vulcanized to form a completely and irremovably enclosed tubular tire.
