    Abstract: A cable-type tire chain for the tires of dual wheels comprises a pair of side members and a plurality of cross members extending between and connected to the side members and supporting traction elements. The tire chain includes a center member that extends circumferentially over the cross members of the installed tire chain and that draws center portions of the cross members into the space between the tires. The center member comprises a core surrounded by a helical spring. The core includes a cable wrapped helically with wire, and the inner diameter of the spring is greater than the outer diameter of the core so that the spring can move on the core.
