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.

Abstract: The invention relates to a studded air-filled vehicle tire having a rolling direction and comprising a rubber tread with pattern blocks and grooves that-separate the blocks. Premade stud holes are arranged in the tread. Anti-slip studs each include a hard cermet piece that has a substantially quadrangular shape with diagonal dimensions are in at least part of the stud holes. At least part of the anti-slip studs arranged in the stud holes are orientated so that one of the diagonal dimensions of the hard cermet piece is located in the rolling direction or forms an angle, not larger than a toe-out angle with respect to the rolling direction.
