Show Studded tires vs tire chains study outlined from research stop-and-go traction provided by studs when used on the rear wheels only, the driver may easily be misled into feeling that this added traction will hp on a curve, only to discover discov-er that the front end of the vehicle skids out of control, a phenomenon with which he is probably not at all familiar. This type of situation may indeed in-deed cause him to slide through an intersection where he had attempted to make a turning maneuver," he cautioned. "For this reason," concluded Whitehurst, "it is recommended that those who use studded tires should have them installed on all four wheels instead of on the rear wheels only as is customary. But whether they use studs or chains they should slow down on icy road surfaces." While studded snow tires materially ma-terially increase both stopping and pulling ability on glare ice, the greatest improvement is achieved by using reinforced tire chains, according to a University Uni-versity of Tennessee researcher, Prof. E. A. Whitehurst. Professor Whitehurst reported report-ed on the 1987 and 1968 test projects of the National Safety Council's Committee on Winter Driving Hazards at Stevens Point, Wise, of which he serves as director. These tests also disclosed for the first time that when these traction devices studded tires and chains are used on the rear wheels only, the cornering corn-ering capacity of a vehicle is not materially improved. "With studded tires on the rear wheels the cornering speed of the test vehicle was increased in-creased 6 per .cent; with rein- forced tire chains on the rear wheels, 10 per cent," Prof. Whitehurst said. '"When studded stud-ded tires were used on all four wheels, however, the cornering speed was increased by 24 per cent." Since studded tires are normally nor-mally used on the rear wheels only, Whitehurst explained that this practice could subject drivers to a hazardous situation in turning maneuvers. "Because of the increased |
