ABSTRACT:
An anti-skid stud which comprises a plug or matrix in which are embedded one or more wire-like strands of great wear resistance material such as iron, steel, siliceous material, plastics, etc., which protrude from the matrix. The stud is installed in the surface of tires with the wire-like strands protruding to the road surface. These protrusions penetrate ice and snow surfaces to provide anti-skid traction, however on surfaces such as bare concrete these protrusions flex and do not penetrate the surface to cause excessive erosion of the concrete surface.
