AutoSock, an Alternative Traction Device (ATD) for commercial vehicles, has now been approved for use in 45 U.S. states where chain requirements are in effect and others where formal approval is not required as long as the ATD does not cause damage to the road surface. AutoSock is currently in the process of obtaining approval in the remaining U.S. states.
Through 2012, over two million pairs of AutoSock were in use worldwide. AutoSock is a patented textile cover that uses high-performance fibers to maximize friction on snow and ice covered roads, according to the company, and it features a specially designed surface pattern that makes the total contact area exposed to dry friction as large as possible. AutoSock is compatible with ABS and traction control systems and is designed for vehicles or combinations over 10,000 lbs GVWR with five or fewer axles, including Class 3-8 medium- and heavy-duty trucks with tire sizes from 17 in. to wide base singles.
AutoSock features and benefits, the manufacturer pointed out, include:
• Quick and easy installation in less than five minutes per wheel minimizes a driver’s exposure to weather and traffic and increases available Hours of Service under new regulations;
• At about 10 lbs each, provides a weight savings compared to an 80-lb set of traditional chains;
• Easy to store inside a cab or tool compartment, minimizing damage risk;
• Almost no noise emissions or vibration while driving, enhancing driver comfort; and
• Does not damage road surfaces, unlike metal chains, because its material is softer than concrete and asphalt.
