<p>The disclosure herein discloses a grip for a vehicle tire which consists of an elongated body having an inclined ramp portion, a nose portion and two parallel sidewalls tapering to the nose portion; a first series of transverse projections spaced longitudinally along the upper face of the ramp portion and a series of teeth provided longitudinally along the lower edge of each sidewall provide traction between tire and an icy surface. A second series of longitudinally spaced transverse projections along the under face of the ramp portion provides additional gripping action. For use in deep snow, however, the grip is engagedly combined with a similarly-shaped elongated body, the latter serving as the tire-engaging part of the combined device and the grip serving only as the snow traction part thereof.</p> |
