When the roads turn icy or snow piles up, these Konig K-Summit chains bite in with a diamond-shaped pattern and square links that keep steady contact with the surface. The traction plates break through packed ice, while the smaller link size gives a smoother, less bumpy ride. The design keeps you moving when lesser chains start slipping.
If your vehicle has tight wheel-well space, these chains are built just for that. They ride only on the tire tread and need 0 mm of internal clearance, so there’s no contact with suspension or brake parts. They’re SAE Class S compatible and leave your rims untouched for a clean, protected setup that works where other chains can’t fit.
Once mounted, the K-Summit chains automatically tighten and center as you drive. That means no pulling over to readjust. The mechanism keeps a uniform grip on the tire—even on worn treads—so traction stays consistent mile after mile. You get peace of mind knowing they’ll stay snug without extra tools or fiddling in the snow.
Each chain attaches directly to a wheel lug nut using the supplied fixing key and adapter. It’s a straightforward connection that stays secure, and when you’re done, the external release system lets you remove everything quickly. Foldable arms make storage simple, and the included nylon bag keeps them ready for the next storm.
From the sturdy arms to the geometric structure that holds its shape under load, every part of these chains is engineered for strength and precision. They come as a pair for 14" – 19" tires and include 17 mm, 19 mm, and 21–22 mm lug nut adapters. With their 5-year warranty, these K-Summit chains give dependable performance season after season on snow-covered roads.
These chains fit the following tire sizes:
Ratings & Reviews
Bought these for my Model X and so far I’ve only needed to use them a few times. These chains were pretty easy to put on. The hard part is making sure the lug nut grabber has thoroughly grabber the nut so the chains clamp down properly. Watch some YouTube. Videos
The instructions are pretty clear on how to adjust these for your tire size. Do that adjustment as soon as you can after purchase. As this is not fun to do on the side of the road.
It works! Not so easy to learn how to use/installation (lack of online and general installation guide) but once figure out, it works. It's costly (10 times more expensive than normal snow chains) but I guess that's the price to pay for Porsche chain; yaiks! I wish they address those 2 issues in the future; price and installation instruction.
I'm giving these four stars as I haven't tried them in snow. I bought them in Spring to save a few $$.
The instructions are a little weird as the English translation isn't great and the pics are unclear in a few places. The instruction videos on etrailer are very helpful.
You MUST set these up before you need to use them as they have to be sized to your specific tire dimensions and lug nut.
The tightening wrench has a torque setting. When you fit the lug nut connection you tighten until you hear a click. It ends up really tight and took a little work to remove.
After the lug connection is on, you tighten a ratchet before rolling the vehicle to complete installation. I didn't notice at first you only tighten until you see a line of red stitching. Because of that the chain didn't go on property. I reset and tried again and all was fine.
These go on very tight. At least if you follow instructions to the letter.
Hope they do what I need them to do in winter.
Etrailer.com did an excellent job in shipping the two sets of chains that I ordered. Super detailed tracking information was awesome. It always makes me nervous when buying over the internet that a retailer may ship the wrong item especially considering how many different sizes these chains are available. I will point out that the chains were advertised as Thule. However, I received one set of Thule and the other set was Konig who bought out this chain line from Thule in 12/2015. In comparing the two brands side-by-side, the components and build are absolutely indistinguishable from each other with the exception of the brand stickers. I have no reason to believe one brand to be superior to the other. The K56's fit my Honda Accord 225/65/17 tires like a glove. They are a combination of simplicity and sophistication, if that's possible. I can't wait to try them out on the ice and snow. Thank you etrailer.com and I would definitely order from you again.
It fits! I have a Tesla Model S with 21" staggered wheels, I don't need chains but I must carry to comply and it gives me peace of mind.
etrailer can't recommend it, but Konig's website did Say the XL K55 model fits 265/35-21.
It came with 3 size of nut grabbers and nut spacers. There was no manual in the box but I found it online. The manual is needed because the chain can be made wider removing some springs and the manual says how many according to the tire size.
Excellent service. They helped me find a product that I could not find.
I am very impressed with the quality, unique design and ease of installation. I have test fit these chains to our vehicle and the fit is great for our application where the chains cannot extend to the inside of the tire as there is no clearance. Having said this, to date we have not used the chains in the snow. We live in the Sierra Mountains of California in a location where we are required to carry chains. However, in our area it is rare that the road crews have not cleared the snow to the point where four-wheel-drive will suffice. I'm assuming I would rate these chains with five stars after actual road use.
I am using K-Summit chains on a Chevy Bolt to get to a house in the Blue Ridge Mountains. I need the extra grip to get up some steep hills if there is snow or ice on the ground. The chains successfully allow me to climb hills through snow at least 4 inches deep and over ice where I could not otherwise go. The chains are easy to install and remove. The problem is that after a few uses several of the D Links broke. The advantage is that the Konig sent replacement chains under warranty. (There was a bit of a communication mix up between Italy and the United States. If I was a bit more persistent, I'm sure the warranty process would have been much quicker.) Haven't yet had a need to put the replacement chains to much use, so don't yet know whether I received a defective set of chains or whether this design is not suited to my use (which shouldn't be overly demanding). The purchase was quick and easy with etrailer.com. The warranty replacement was handled directly by Konig.
We have a BMW X3 in the foothills of the Sierras and need to have chains on hand. Normal chains are not an option for the BMW X3. On the surface theses seem like a very slick product. In reality maybe for some. There are limited Choices for the X3, The K-Summit Size: K45 seem OK but I have issues and concerns.
Once received you have to fit the chains to your tires. DO HIS IN THE GARAGE BEFORE YOU GO ANYWHERE. Doing this on the road in the snow would be a pain. If you like IKEA you’ll love the instructions. (Well maybe not that bad). Go on-line and look at some videos. I needed to remove 4 “regulation elements” on each chain to fit our tires. Tools are provided but I used a metric socket and a cordless drill to help with this and it took maybe 5 minutes. With hand tools the 8 total “elements’ would have taken 20 or more.
Now basically shove the chain more or less in place with plastic “pads at 10:00, 2:00, 4:00 and 8:00 O’Clock positions on the tire.
Next make sure you have the correct size lug nut adapter and the proper spacing from the rim. Supposedly just put the adaptor on a lug, with the indicating tip toward the rim center and tighten the bolt with the supplied wrench.
I found issues with the 17mm lug adapter and the 17mm BMW lug. The BMW lug is not very tall and the adapter never felt very securely seated to me. (Yes I made sure the adapter is seated correctly in the “cup”; instructions mention this). This may be better on other vehicles.
Lastly, pull the crank until you see the red line on the nylon strap. Dive forward 50 feet or so so the chains will move onto the tire. We got out of the car to check and it still required a couple of short toe kicks to fully get them securely on.
In summary they seem to “work OK”. I didn’t find any better options available for the X3. Once set up they are fairly easy to install with the exception of the lug nut connection which I found insecure and fussy on the X3. The plastic components give me concern for durability. Will they become brittle and break in cold temperatures or over extended use? Time will tell. Very costly if there is a failure on the road warrantee not withstanding.
These are adapters to allow the associated chain set fit some uncommon tire lugs. The adapters work flawlessly. Ordered them for the chain set as the rims on my vehicle require them. Fit perfectly as did the chains after adjustment.
However, I don't know how well they actually work on snow and ice. Based on experience with a number of other chain sets I see no reason to doubt their reliability and efficiency.
Backstory: Ordered a set for a trip to Colorado over Christmas & New Year's as we were expecting snow and ice as we were planning to travel to Estes Park, Denver, Colorado Springs, Salida, Buena Vista, Leadville, etc. Received our order quickly and correctly. Tried chains on tires and made fitting adjustments per instructions for exact tire size. Played with the chains a few times to make sure I knew how to get them deployed quickly. They are extremely easy to put on once they are adjusted. Watch the video - it really is that easy.
Fast forward a few weeks, we went on our trip. Got not much more than a dusting the whole trip and never had to put the chains on.
Meanwhile, back home, there were something like 129,000 poor bxxxxxxs waiting for the roads to be cleared and power to be restored from the huge ice and snow storms.
At the end of our trip we drove home over clear roads surrounded by big piles of plowed snow. Arrived home to find our neighbors huge tree uprooted and blown over. We didn't receive any damage. Next day got the hound out of doggie jail pretty much as if nothing had happened.
I like these chains!
This is an update to the review for the 2017 MINI Cooper with 205/45-17 tires. By taking off both spacers (red and silver), I was able to get the chains to center on the tire - I might even be able to put one of the chain tightening screws back on, maybe more as the tread wears down. So I think they're going to work well this winter. I'll bump the review up to five stars when I can figure out how to get them to easily fit into the carrying case.
Had these K-Summit "chains" for a Toyota Corolla for 5+ years, and they worked so well that I immediately bought a new pair to fit my 2013 Honda Accord (different tire size), and they also work great. Used them the other day in 6" of unplowed snow, on the hill I live on. As long as you go slow (I usually drive < 25 MPH) they just keep moving you forward. Two quick notes: 1) I noticed going uphill that my wheels started skidding, then stopping, and repeated that annoying cycle, which made it harder than usual to continue moving forward. I quickly figured out that this was the way the anti-spin system worked on the car (which doesn't want you to spin your wheels). I disabled that and that odd behavior stopped. 2) The fitting guide, which tells you how many "links" or "regulation elements" (as the instructions calls them) to remove to fit the chain to the tire, is assuming you're placing them on all-season tires. When you use snow tires, as I do, you have to remove more links to get the chain to fit correctly. This is not a problem, but it's useful to know. The representative from Thule, the company from whom I bought my original set, admitted that they should mention this in the instruction guide.
So these are really expensive but there weren't a lot of options for my wide 22" tires. Are they worth it? Absolutely! These are my first chains so I wasn't sure what to expect, but once you make the initial size adjustments, it is super easy to get these on! I've seen other cars on the side of the road struggling to get their traditional chains on, where you have to lay down the chains, drive over, then wrap them around the tire and secure them.
With these, I just unfold them, push them onto the tires as far as they will go over the top and front and back, and slowly drive forward until they auto-adjust in place. A quick stop to double-check and make sure they are on all the way, and off I go.
Love them!
Awesome grip. Easy to put in and take off. Great for low-clearance (oversized) wheels. Worth the price.
Great quality, easy to setup and install, and convenient to carry. Thanks etrailer.com for providing additional instruction videos as well. Recommended.
These chains fit my 2022 chevrolet equinox perfectly. The manual on the car says not to use snow chains. There's no clearance behind the wheels and chains would hit and possibly mess up the brakes. I didn't know this untill I tryed to put chains on and they were no clearance and looked at the manual.I found these k summit chains I knew I had to have them. I fitted them on my car, they are so easy to put on and take off. I haven't had any snow to use them yet but winter is just starting and I will up date my review after we get snow.
etrailer was awesome to deal with, processed my purchase and shipped it out very quickly. I like these chains, although they have some trouble self-tensioning on my tires. The chain on the inside gets caught in the tread of my tire, so you have to push it up and past that part to get it installed properly.
I received the packaged and I'm very satisfied so far. Tomorrow morning I will fit the chains on the tires to see if my purchased is "A" one.
Great product and fast shipping from etrailer. I purchased the Konig K-Summit chains for my 2011 BMW 535i. They are easy to install and take off. Make sure you install the chains at home before you need them. The lug nut attachments that came in the box would not fit the lug nuts on my cars wheel, so I had to obtain an attachment that did fit. Do not exceed 30MPH when the chains are installed. The chains will come apart and damage your car if you exceed the speed restriction. Unfortunately, this happened to me when using my first pair of Thule K-Summit chains - new tire and body damage $2,000. But if you stay below 30MPH , the chains are great.
I only used it one time during the year,but it sure came in handy. It is particularly useful for me because of the very limited space in the wheel well of the Genesis coup. Fitting to the lug bolt was a little tricky but did work.
I try to travel into the Rockies at least once a winter so that’s why I bought the chains
After having a hard time figuring out how to assembly it due to lack of written instructions along with the illustration, I was able to mount them with technical help from the manufacurer engineering dept. I am very unsure if I made a good choice in purchasing this product. I was led by the marketing of easiness of installation. Now I realize that if one link on the chain breaks, the whole chain safety is compromise whereas in a standard cheaper model (+- $40) you can just remove one link across the tire and replace it easily.
According to Tech. dept. from Thule if on single linkin this chain breaks you can use an emmergency link tighted with plier, but the chain needs to be mailed back to Thurle for repair or replacement. This is a hassle for such a high priced, premium, "ahead of time design". Sure the idea is good, but needs improvement.
The same design that makes it easy of use, renders it useless in case of a broken link. I have not driven with them on snow, but I already see its flaw and I am unsure if I made a wise investment.
It came with one year warranty, but you get the hassle of having to return them for replacement while you go to Pep Boys and buy a cheaper reliable cable chain while the white elephant is in the shop.
What if it breaks after the one year warranty? Waht happened to your U$ 405 plus shipping investment that should bring you peace of mind?
These are a few thought I want to share with you.
Have a great day.
Fits tight as a drum! The K44 is nice and snug on my 19’s. Kinda nervous about the stress on the tensioning strap and lug nut clinchers, but these things will be sweet if the Engineers did their job right! Only plan to use these for a few miles at a time, so if all goes well they’ll last me a good long while
