Abstract
An emergency motor vehicle tire traction improving device for attachment or mounting to a conventional motor vehicle tire is made substantially totally of multi-strand polymeric plastic rope and includes three or more separate lengths of the rope connected together in a pattern that defines a ladder having inside and outside parallel, coextensive runners and a plurality of transverse rungs connecting corresponding points of the runners, whereby the device is mounted to the tire by drapping it over the tire with the runners parallel with the direction of rotation of the tire and the rungs across the tire treads, with one end of each runner connected to the other end thereof and an elastic device attached to one of the runners pulling that runner uniformly toward the axis of the tire. When so mounted to the tire, the tire traction, particularly on ice and snow, is improved. All embodiments of the tire traction device are comprised of three or more separate lengths of the polymeric rope: one length provides one runner, another length provides the other runner and one or more other lengths provide the rungs that are threaded to the runners.
