ABSTRACT:
The invention relates to an anti-skid stud the operation of which is based on a larger than conventional diameter of the tip part (1) of the anti-skid stud and on its primarily annular contact with the road surface during normal driving, with a slight projection of the tip and with a small surface pressure, the projection increasing in situations in which it is needed, for example during braking, the external force P caused by the braking tilting the anti-skid stud in its position, whereupon the projected edge 5 of the tip part will penetrate over its entire width into the road surface. The stud includes a mantle surface which is made of a material harder than a central portion of the tip.
