SAFER WINTER TIRES USING OIL-EXTENDED NATURAL RUBBER

THE GRIP OF OIL-EXTENDED NATURAL RUBBER INTER TIRES MADE OF BOTH CROSSPLY AND RADIAL-PLY CONSTRUCTION HAS BEEN ASSESSED DURING THREE SEPARATE TRIALS IN SCANDINAVIA. THE TESTS HAVE BEEN CARRIED OUT ON ICE AND HARDPACKED SNOW AT TEMPERATURES AS LO AS-15 C. THE VARIABILITY OF ICE MAKES IT DIFFICULT TO OBTAIN RELIABLE DATA UNLESS A LARGE NUMBER OF MEASUREMENTS ARE MADE ON SEVERAL DIFFERENT OCCASIONS. IT HAS NOT BEEN POSSIBLE TO CORRELATE THE VARIABILITY OF THE RESULTS WITH THE MORE OBVIOUS CLIMATOLOGICAL FACTORS SUCH AS TEMPERATURE OR AMOUNT OF SUNSHINE. THE RESULTS PRESENTED HERE SHOW THAT OIL- EXTENDED NATURAL RUBBER HAS BETTER GRIP THAN CONVENTIONAL HIGH HYSTERESIS SYNTHETIC TIRE TREADS AND MAY EVEN PERFORM BETTER THAN STUDDED CONVENTIONAL TIRES ON SOME OCCASIONS. THE USE OF OIL-EXTENDED NATURAL RUBBER WINTER TIRE TREADS WOULD MAKE A SIGNIFICANT CONTRIBUTION TO ROAD SAFETY UNDER INTER CONDITIONS. (AUTHOR)
