This invention is a traction device for a vehicle wheel. It comprises a shoe member adapted to seat onto the tread of a tire. One side of the shoe has upstanding bars for supporting an inwardly extending curvilinear member for bracing against the side wall of the tire adjacent the rim of the wheel. The other side of the shoe is provided with upstanding bars which support a rectangular frame to which is pivotally hinged a base on which is mounted a laterally movable curvilinear member which is clamped against the outside wall of the tire adjacent the rim of the wheel. The clamping device includes a screw means having a head keyed to be rotated by a releasable crank. The clamp device of this invention incorporates screw means which moves to tighten and loosen the clamp member in small increments as well as hinge or pivot means which radially moves a substantial distance to position the clamp member adjacent the tire side wall.
