NATURAL RUBBER IN WINTER TIRES AND INDUSTRIAL TIRES

THE SKID RESISTANCE AND WEAR CHARACTERISTICS OF NATURAL RUBBER AND SYNTHETIC RUBBER ARE COMPARED IN WINTER TIRES AND INDUSTRIAL TIRES, WHERE LOW TIRE SURFACE TEMPERATURES ARE EXPERIENCED. OIL EXTENDED FORMULATIONS OF BOTH THE NATURAL AND SYNTHETIC RUBBERS ARE ALSO TESTED. FOR WINTER TIRES, THE BEST SKID RESISTANCE AT CONTINUALLY SUB-ZERO TEMPERATURES IS OBTAINED WITH NATURAL RUBBER TREADS. IF THE TIRES WILL ALSO BE DRIVEN ON WET ROADS, OIL-EXTENDED NATURAL RUBBER WITH POLYBUTADIENE ADDED PROVIDES THE BEST BALANCE OF PROPERTIES. STUDS INCREASE SKID-RESISTANCE IN SNOW, BUT HAVE LOW SKID RESISTANCE ON WET ROADS, AND MAY LEAD TO EXCESSIVE ROAD WEAR. FOR INDUSTRIAL TIRES, NATURAL RUBBER ALSO OFFERS THE BEST COMBINATION OF WEAR RESISTANCE, AS WELL AS LOW ROLLING RESISTNACE. IN GENERAL, THE ROUGHER THE CONDITIONS, THE GREATER THE RELATIVE SUPERIORITY OF NATURAL RUBBER. /HSL/
