A device for attachment to an automobile wheel to assist in driving the automobile out of snow, mud or other material in which the automobile may be stuck. The device includes a means for attaching radial arms to the outerface of an automobile wheel so that the radial arms extend, parallel to the face of the wheel, approximately to the periphery of the tire on the wheel. The radial arms are provided, at their ends, with heel elements which will grip the surface upon which the automobile rests. As the automobile wheel is caused to turn, the device will then serve to "lift" the automobile from its stuck position.
