Title: Tire chain construction

Abstract: A traction increasing chain for vehicular tires that may be installed thereon without moving the tire relative to the surface supporting it. The chain provides plural rigid side elements articulately interconnected and carrying cross-chains, all so configured that when installed on a tire the cross-chains will cover a portion, but not the supported portion, of the peripheral surface of the tire. A medial fastening linkage maintains the chain on the tire during usage.
