ABSTRACT:
A nonskid structure applicable to pneumatic tires comprises a pair of metal rods of suitable length and elasticity, folded over so as to build rectangular frames, open on one of the longer sides. At the open ends the metal rods are bent downwardly in an orthogonal direction to the plane defined by the frames. The intermediate portion of the longer side is slightly curved. The shorter sides of the frames have the end portions bent at right angles in an orthogonal direction to the plane defined by the frames and terminate with a hook. Preferably, the shorter sides comprise an undulated portion and/or a strip of corrugated sheet for better grip on snow or ice.
