Abstract
Described herein are several embodiments of an anti-skid stud for insertion into the rubber tread of an air-filled vehicle tire. The stud can include a body that has a bottom flange, a shank element that extends outwardly from the bottom flange, and a hard cermet piece made from a material different than the body. The hard cermet piece is positioned at least partially within the body. The bottom flange can have a substantially quadrangular shape that defines diagonal dimensions. The hard cermet piece can be substantially lozenge-shaped in cross-section and define mutually different diagonal dimensions that extend in a direction perpendicular to a total length of the stud.
