AutoSock HP 745 Winter Traction Aid, For High Performance Tires for $49.43

Unexpected winter weather can create driving conditions demanding more traction than conventional tires -- or even snow treads -- can provide. But tire chains are bulky to store and can be difficult to put on in cold, snowy weather. Now there is an easy-to-use alternative to chains: Designed in Norway, AutoSock is a new and innovative lightweight fabric-based, temporary traction aid for cars and trucks that is easy to mount and gets a grip on slippery surfaces as snow and ice.
