  • Patent number: 4219065
    Abstract: A tire protector for reducing wear on the tires of heavy vehicles consisting of two or more parallel rows of spaced apart chain links. These links are joined by couplings members and consist of metal bars or wires which are bent so that they encircle each two chain links and that the ends of the bars or wires overlap side by side. These overlapping ends are positioned to face upwardly and flat when the protector is mounted to a tire. As a result only a relatively small area comes continually with contact with the ground and is thus exposed to wear and tear. This contacting area is strongly enforced due to the thickness of the sidewise overlapping ends, as a result, parts of the protector, such as the chain links and the bars or wires which form the coupling member, can be made fairly thin as they are not exposed to considerable wear thereby reducing the overall cost of producing the protector and also extending its lifetime.
