Many modern cars have almost no space behind the wheel, making regular chains a no-go. These K-Summit chains solve that by riding only on the tire tread—nothing wraps around behind. The mount locks onto a wheel lug nut and the system clears suspension and brake parts entirely. With an internal-clearance requirement of 0 mm, they meet SAE Class S standards and protect your wheel rims since the chain never touches them.
When snow hits, you don’t want to keep pulling over to re-tighten chains. Once the K-Summit is attached, it automatically tightens and centers itself as you drive. The built-in ratcheting mechanism uses the tire’s rotation to keep the chain snug, so you get consistent traction without extra steps. It’s an easy way to keep rolling steadily through snowy roads.
The diamond layout keeps more chain in contact with the road at once, which means constant grip instead of the bump-and-slip feel of ladder patterns. Each square link digs in evenly, and the traction plates break through icy layers so you stay in control on slick pavement. It’s a steady, confident ride through light snow or packed ice.
When the drive’s done, pop the external release and the chains come right off—no wrestling underneath the car. The foldable arms collapse for compact storage, and everything fits neatly into the included nylon bag. You also get three lug-nut adapters (17 mm, 19 mm, and 21–22 mm) to match your setup, all ready to go wherever winter takes you.
These chains are engineered for reliable traction while keeping your ride smooth at moderate speeds. Konig rates the K-Summit for 30–35 mph use, giving you solid control and predictable handling in snow-covered conditions. It’s a smart balance of grip, comfort, and protection for vehicles that demand precision.

Still great! Didn’t need them that often last season, but always nice to know they’re in the trunk if I do. Never been unable to complete trip with these “chains” attached.

These worked great. The first time I used them, I didnt tighten the screw enough and one of the chains came off while driving. But after learning to tighten them enough, I had no problems. It was a mild winter, but at least I know that driving 20 miles in 5 of unplowed snow up the mountain highway isnt a problem. And I finally figured out how to get them back into the case.
