Experiments with new tire traction chains made with plastic rather than steel are being conducted by the Alaska Department of Highways. The plastic, called elastomer rather than steel, is harder than rubber and is reputed by the manufacturer to last up to 30 times longer than steel and to provide up to 71 percent more snow traction than normal snow tires. Results of the initial tests show that the chains can be driven on bare pavements at a speed of 60 mph with little or no vibration. The elastomeric band lies flat against the tire tread until skidding begins, which will than cause the band to turn and dig into the snow. The tread returns to a flat position when skidding stops. These results show immediate advantages over steel chains, although testing will continue in an effort to improve winter driving safety.
