The K-Summit is the ultimate snow chain on the market today. The K-Summit is uniquely designed to ride on only the external surfaces of the tire so you don't need to worry about clearance issues on the inside of the tire or interference with ABS braking, suspension or steering components. The K-Summit is also one of the easiest chains to install in three easy steps. You simply lay the chain on the tire, attach it to one of the bolts, activate the ratchet and you're done. The chain automatically self-tightens and self-centers itself as you drive away. You don't need to keep other components mounted to the wheel over the winter like other chains. The K-Summit was produced in Italy and the craftsmanship and attention to detail are evident. It is made of special alloy plates and strengthening ribs along with zinc-plated pins and hard metal core rivets all designed for maximum grip, endurance, reliability and resistance to abrasion and laceration. The geometric design of the arms and the high toughness of the material won't allow the chain to come off the tire, even in extreme conditions. In addition the innovative ratchet system has a force multiplier of nine times so it allows effortless fitting and a safety lever to avoid accidental openings.

I need to have tire chains for my new 2016 Golf R when I go up the mountain (though I hope not to need them very often), as I'm not willing to risk getting stuck in icy conditions. I extensively researched available options for the very low-profile tires with very limited clearance on the Golf R. I concluded that I had little choice but the K-Summits despite how expensive they are. (The only other options I discovered were: Spike Spiders, which cost even more and require that the mounting be left on the wheel all winter; and a second set of wheels with studded tires, which costs LOTS more and would be very inconvenient.) I have now mounted the K-Summits on my R and tested them in my neighborhood (on dry pavement), and they fit perfectly (see photos)! They were also very easy to install and remove. Best of all, the chains fit exactly into the longitudinal grooves on the R's summer performance tires (as seen in 2nd, close-up photo), which I hope and believe will help to...
The good news is that these chains actually DO self-adjust onto the tire - ONCE YOU GET THE SIZE CORRECTLY ADJUSTED. The pictorial guide had me remove 4 of the cross bolts, and I had to remove one more because I have "mud and snow" tires. MAKE SURE you get these sized and adjusted BEFORE you get to the snow. I would hate to have to try to do this in the cold and snow on the side of the road.
The bad news is that the ratchet mechanism is too flimsy, and you can EASILY damage it by over-tightening while ratcheting in the chains. So be careful.
Note to Thule: If you had actually used words in your instructions (instead of cryptic and hard-to-understand pictorials) I might have avoided this problem. In this case, a couple of words (e.g., "Do not over-tighten the ratchet, because we used a flimsy design") would have been worth a thousand pictures.
Also - the pictorial instructions on how to select the correct stand-offs for the lug nut bolt were VERY...
Bought this for Mrs. TiredLawyer's Range Rover Sport SUV because she was a bit concerned about putting on normal chains. Very slick product. Once you have the chains fitted, it takes maybe 30 seconds to put these on, and can be accomplished without breaking a nail. In fact there are videos all over youtube that show how to install. Basically shove the chain part more or less in place, put the adaptor on the lug, tighten, then pull the crank until you see the red line.
Now, note I said "once you have it fitted." Getting the chains to fit your tire is a little bit of a challenge. First, the Amazon-recomender that tells you what model (K66 in my case) to buy tells you the wrong model. Go to the Thule website, use their fitment app, put in your tire size (e.g., 275/40R 20), then come back to Amazon and buy that recommended size for a couple hundred less than the Thule website.
Fitting involves finding your model chart in a mildly confusing book and...
