Thule, who is no stranger to external car accessory parts, has come up with a new and innovative snow tire chain that is both practical and easy to attach.  Crafted of metal studs and a plastic body, the K-summit attaches to one of the tire’s lug nuts and then using a crank tightening system fits into places providing that much needed grip to traverse even the most slippery of slopes.

The below video screams ‘concept’, but since it’s a 2008 product, at least according to their catalog, it should be available now, right?
