ABSTRACT:
A traction-enhancing device that is releasably attached to vehicle tires. A rigid base member having a central core and plural arms radiating therefrom is placed into overlying relation to the side of a tire. Plural flexible cords and rigid rod members in axial alignment therewith interconnect a like number of tread-overlying road-gripping members to a capstan mounted centrally of the base member. Rotation of the capstan draws the road-contacting members radially inwardly into tight-fitting engagement with the tire and effectively creates an enhanced tread. Counter rotation of the capstan enables the road-contacting members to be swung away from the tread so that the device can be removed from the tire.
