Made from a high tech woven fabric which increases tire to road friction, the AutoSocks are comfortable in use and do not cause vibration or noise when driving, unlike snow chains. They go on easy and quick, and are light, plus they dont take up much room in your car trunk, and are reusable and machine washable. It really is the perfect emergency winter driving aid to get you out of some tricky situations. If you are looking for a cheap but very effective alternative to snow chains you should buy a set of these.
