Abstract
Anti-skid stud for road vehicle tires composed of a tungsten carbide rod enclosed in a sleeve. This sleeve, made of a plastic material, has a cylindrical or frustoconical stem with at least one flange flush with the tread, the diameter of the flange being greater than the largest diameter of the rest of the sleeve. This arrangement provides a high degree of stability of the projection of the carbide rod beyond the tire tread throughout the period of use.
