Abstract: A traction enhancement device for vehicle wheels for use in the event of an emergency. The traction enhancement device includes a traction member for being placed across the periphery of the tire of a drive wheel. A first strap is connected with one end of the traction member and is provided with a series of closely spaced ramped serrations. A second strap is connected with the other end of the traction member and is provided with a sleeve for receiving therethrough the ramped serrations portion of the first strap, wherein a detent engages the ramped serrations in a ratchet-type manner so as to permit the first strap to slide in the sleeve in only one direction. The traction member may be provided with an engagement surface having an irregular contour to thereby enhance traction of the tire with respect to the surface in question.
