An alternative traction device (ATD) from AutoSock Operations AS has now been approved for use in 45 U.S. states, the company announced.

The AutoSock AS is a patented textile cover that uses high-performance fibers to maximize friction on snow and ice covered roads, the company said. The ATD 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.

“AutoSock is a winter aid that maximizes friction on snow and ice-covered roads,” said Bernt J. Rosli, CEO. “Compared to traditional chains, it is much safer and easier for drivers to put on a vehicle, weighs less and provides comparable performance. Over two million pairs of AutoSock are now in use worldwide.”

The device 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 Operations said it can be installed in less than 5 minutes per wheel, weighs about 10 lbs., does not damage road surfaces and can be easily stored inside the cab or tool compartment.
