NEW TIRE STUD DEVELOPMENTS

TESTS OF RECENTLY DEVELOPED TIRE STUD DESIGNS SHOW PROMISE THAT THE SAFETY AND CONVENIENCE FACTORS OF STUDDED TIRES CAN BE RETAINED WITH CONSIDERABLE REDUCTION IN ROAD WEAR CAUSED BY THEIR USE. MOST NEW TIRE STUDS ARE DESIGNED SO THAT THE CARBIDE PIN WILL MOVE FURTHER INTO THE STUD BODY IF THE PROTRUSION OF THE STUD FROM THE TIRE EXCEEDS A CRITICAL LIMIT. THE GREATER THE PROTRUSION, THE GREATER THE IMPACT FORCE, WHICH CAUSES THE ROAD WEAR. NEW TIRE STUDS HAVING BUILT-IN PROTRUSION ADJUSTMENT CAPABILITY MAINTAIN NEARLY UNIFORM PROTRUSION THROUGHOUT THEIR LIFETIME WHTHOUT BEING AFFECTED BY WEAR RESISTANCE OF RUBBER COMPOUNDS, DRIVING SPEEDS, OR ROAD SURFACES. TIRES WITH THESE STUDS SHOW AN INCREASE OF 75% IN COEFFICIENT OF FRICTION ON SMOOTH ICE AS COMPARED TO IDENTICAL TIRES WITHOUT STUDS. /HSL/
