ABSTRACT The traction device of the invention is for use with a vehicle wheel supported by lugs and having a tire. The traction device has a base with openings for the reception of at least two but less than all, the lugs for supporting the base. A plurality of spaced radial arms are supported by the base with each having an end adapted to extend beyond the outer periphery of the tire and protrude into an icy surface. Each of said ends is adapted to lie in a vertical plane adjacent to the outer side wall of the tire. The end of each arm may advantageously be free to move in and out while being spring biased outwardly, be threadably attached to the arm for movement inwardly and outwardly, or be pivotally connected to the arm for movement into and out of an operative position. The said ends may extend different distances beyond the outer periphery of the tire. Perferably, the base is secured on less than all of the lugs and has a bearing recess accommodating a nut on a lug to which the base is not secured.
