ABSTRACT:
A tire chain comprises an elongated inner side member adapted to form a circle of predetermined circumference about a rim of a vehicle wheel at the inner side thereof, the inner side member having co-operable fastener elements at opposite ends thereof which are joined to complete the circle. Cross members form a zig-zag pattern with opposite ends of the pattern adjacent to the fastener elements, respectively. The pattern includes a plurality of spaced inner vertices adjacent to the inner side member and a plurality of spaced outer vertices remote from the inner side member and adapted to be positioned adjacent to the rim at the outer side thereof, with the cross members extending back and forth across the tread of a tire mounted on the rim. The inner vertices are attached to the inner side member at predetermined positions by connectors intermediate the vertices and the inner side member. The outer vertices are provided with connectors to which a tensioning device is coupled for drawing the outer vertices toward the rotational axis of the wheel. While the spacing of the inner vertices is essentially fixed, the spacing of adjacent outer vertices is adjustable.
