THE EFFECTS OF STUDDED TIRES

THREE AREAS WERE INVESTIGATED: (1) THE RELATIVE DAMAGE, IF ANY, TO PAVEMENTS CAUSED BY STUDDED TIRES, DEICING CHEMICALS, AND OTHER MATERIALS; (2) PAVEMENT COMPOSITIONS THAT MIGHT RESIST SUCH DAMAGE; AND (3) THE EFFECTS ON HIGHWAY SAFETY OF STUDDED TIRES. TENTATIVE FINDINGS INCLUDE: (1) SEVERITY OF PAVEMENT WEAR IS DIRECTLY PROPORTIONAL TO AMOUNT OF STUDDED TIRE TRAFFIC; (2) THE ABRASIVE EFFECT OF STUDDED TIRES IS RELATED TO THE DISTANCE THE STUDS PROTRUDE BEYOND THE TIRE SURFACE; (3) ONLY NOMINAL IMPROVEMENTS WERE MADE IN MORE WEAR RESISTANT SURFACINGS, WITH THE EXCEPTION OF AN EPOXY-SAND MIXTURE WHICH DISPLAYED SUPERIOR WEAR RESISTANCE; (4) USE OF STUDDED TIRES WOULD REDUCE PAVEMENT LIFE AND INCREASE MAINTENANCE REQUIRED; (5) VEHICLE PERFORMANCE ON ICE IS SIGNIFICANTLY ENHANCED WITH STUDDED TIRES, ESPECIALLY ON WARM, CLEAN GLARE ICE; (6) USE OF STUDDED TIRES IS DETRIMENTAL TO VEHICLE PERFORMANCE ON BARE PAVEMENTS; (7) THERE IS, AS YET, NO PROOF OF CONSISTENT REDUCTION IN ACCIDENT OCCURENCE OR SEVERITY ON SNOWY OR ICY ROADS ATTRIBUTABLE TO THE INCREASED USE OF SNOW TIRES IN MINNESOTA.
