    Abstract: A removable track for an annular resilient tire having a plurality of elongated transversely extending traction shoes mounted on a belt at spaced-apart positions along the belt. Each of the shoes has a plurality of raised traction bars at the end portions of the shoes and a central raised traction bar at a central portion of the shoe. The traction bars extend generally in a direction from one end of the shoe to the other end with the end bars being positioned on the shoe at a distance from a side edge less than the distance of the central bar from the side edge to provide a flex area for cleaning of the shoes. The traction bars at the ends of the shoes may include transverse bars to reinforce the ends of the shoes and angular bars at an acute angle to the side edges to provide traction in the lateral direction.

    Abstract: A tire having axially spaced rings of elastomeric material with different spring rates and tread configurations to provide variable operating characteristics at axially spaced positions across the tire. Each of the rings has an inner bead portion and an outer belt portion connected by a load-carrying and cushioning intermediate structure which may have radially extending strap members reinforced by a ply of reinforcing cords.
