Abstract
A vehicle tire including a tread intended for a rolling contact against a foundation, the tread having a tread pattern which includes circumferential and transverse grooves for removing water from a contact patch between the foundation and the tire, and anti-skid studs mounted in the tread and including a stud body and a hard metal pin secured thereto. An end of the metal pin, intended against a foundation, is formed as an inclined surface, whereby the metal pin has its end provided with the inclined surface acting on the foundation in an axial direction of the metal pin to a varying depth and the inclined surface being placed relative to a rotating direction of the tire in such an orientation that, as the tire is rolling freely forward, a leading edge of the hard metal pin to impinge first on the foundation is lower than a trailing edge.
