Abstract:
A solid rubber tire with a flexible drive hub having a multiplicity of hub ribs and grooves formed around the periphery of the flexible drive hub and a solid rubber tire tread replaceably mounted on the flexible drive hub having a multiplicity of interior tread grooves and ribs formed around an interior surface of the tire tread, the tread grooves and ribs sized and shaped for interlocking engagement witht he multiplicity of ribs and grooves formed around the periphery of the flexible drive hub.
Abstract:
The Dual Tire Shield of the invention mounts between dual tires and helps to prevent debris from getting into the gap between dual tires and/or damaging the tires when it does so. In some embodiments it can also serve as a runflat for dual tires. Debris can become wedged between the sidewalls of dual tires that face each other, or “inner sidewalls” of such tires. The dual tire shield prevents debris from getting stuck between the inner sidewalls of the dual tires and thereby prevents flats caused by sidewall puncture or bead de-seating due to such debris. The device accomplishes this by: Blocking debris from entering the gap between duals and/or prevent debris from being wedged in the gap; keeping such debris from contact with one or both of the tires even if wedged therebetween; and/or ejecting debris from between the tires. Further, the dual tire shield may be made rigid enough and/or include rigid portions so as to act as a runflat in case a tire goes flat regardless of the reason.
Abstract:
A tire is formed with two treads spaced transversely from each other, two sidewalls terminating in beads reinforced with bead wires, and, between the treads, a connection comprising in its center a wire rod forming a closed loop of diameter intermediate between that of the bead wires and that of the treads. Each tread has its own independent reinforcement, and each sidewall has a rigid zone close to the bead and a flexible zone close to the tread. The connection has on opposite sides of the central wire rod substantially the same structure and the same equilibrium profile when the tire is inflated, and therefore the same radial flexibility, as the flexible zones of the two sidewalls.
