The invention relates to a solid stud, or hollow stud, intended for a vehicle tyre. The prong part of the rivet 11 of the solid stud 10, or the hollow stud 20, which comprises a frame part, is configured as a layered structure in such a way that the prong part comprises a rivet prong 13, 23, 23a and a surface layer 14, 24, 24a which surrounds the prong and which is substantially harder than this. The thickness of the surface layer 14, 24, 24a is chosen such that the rate of wear of the prong part of the stud corresponds to the rate of wear of the tyre rubber. <IMAGE>
