<p>A skid-preventing device includes a stud which is embeddable into the rubber tread of a vehicle tire and comprises a cylindrical stem portion and a bottom flange portion affixed to the base of the stem portion. A hard metal rod engaging pin is affixed to the end of the stem portion opposite the base. A locking ring is engaged over the stem portion between the flange and the pin. The locking ring is of slightly larger diameter than the hole provided in the tire tread for the stud, thus the stud is retained in the tread hole by the frictional force of the locking ring against the inner wall of the hole.</p> |
