Note: To determine whether you can use snow chains on your vehicle, or if chains might affect your ABS/EPS functionality, consult your owner's manual.


The Konig XG-12 tire chains are great all-purpose, winter weather chains. If you live in an area where you're likely to get periodic snow and ice, these Konig chains are perfect because they're durable, easy to mount, and give you constant traction - and they're lightweight and compact, so they store in your vehicle nicely too. If you're more likely to see seriously icy conditions, you may want a chain with V-bar links that can really bite into the ice to give you maximum traction.


These chains are among the easiest and fastest to install because they self-tension and self-center as you drive, ensuring a perfect fit, no matter the profile or wear pattern of your tire. Plus, you only have to get out of your vehicle one time - once they're installed, there's no need to drive forward, stop, and recheck their tension.


Class S Designation

SAE Class S tire chains are designed for use on passenger vehicles with restricted wheel-well clearance. Most newer cars, vans, and small trucks - especially those with large aftermarket tires - will require Class S chains. If you're unsure about the class of your vehicle, consult your vehicle's owner's manual.


SAE Class S Clearance Diagram

These chains will fit your tires provided there is both:

  • A - a minimum of 1.46" (37 mm) between the top of the tire tread and the wheel well
  • B - at least 0.59" (15 mm) between the tire's sidewall and the vehicle

Confirming Your Fit

If you know your tire size, you may think you won't need to test fit your new chains. But there are a lot of variables that can affect whether chains will fit your specific tires, including your tire type, the amount of air pressure in the tire, the amount of tread wear, and the tire manufacturer. You'll also need to know how much clearance is in your wheel well, which you can determine by measuring from your tire tread to the sidewall of the wheel well.


We recommend that you order chains as early in the season as possible to give yourself plenty of time to test fit the chains and reorder if needed. This way, you won't be stuck out in the cold later with snow chains that don't fit.


You can test fit these chains in your garage or driveway, but you'll want to wait until there's snow on the ground to actually drive with them. Likewise, if you're out in the snow and come across bare pavement, you'll want to pull over and remove the chains. Even these low-profile chains can cause damage to the bare pavement, your garage floor, or your vehicle if they break from the wear of riding on a harsh surface.


Installing Tire Chains

Installing these chains is incredibly simple.


Lay chains on the ground to get all the tangles out

1. Lay out the chains on the ground to make sure there are no twists or kinks in them.


Connect the ends of the blue cable

2. Slide the chain behind the tire and connect the ends of the blue cable, which will sit behind the tire.


Connect the hook and link in front of the tire

3. Around front, connect the red hook to the red link.


Feed tensioning chain through clip

4. At the bottom of the tire, feed the tensioning chain through the large clip. Pull the chain up to the center of the tire and secure it to the red hook that is attached to the tensioning cable.


Stretch the hook across the tire

5. Drive forward so that the chain can self-tension and self-center, giving you a perfect fit.


Quick Tips:

  • Lengthen the life of snow chains by drying them after each use before you store them.
  • Check out our installation kit with safety lights and a kneeling pad (PO34FRK) to make things a little easier when you're installing chains out in the snow.

How to Choose Snow Chains for Your Vehicle

To choose the right snow chain, you must match your tire size. Those measurements can be found on the side of your tire.


Tire size on sidewall

185/60-15

  1. (185) - indicates tire width in millimeters
  2. (60) - gives you the aspect ratio (sidewall height as percentage of width)
  3. (15) - denotes the diameter of the wheel rim in inches

These chains fit the following tire sizes:

  • 255/40-20
  • 255/45-19

I had called multiple places and searched Google trying to find chains for my tire size, but no one had results for the make, model, and year of my vehicle. Since I had purchased chains from etrailer years ago for my previous car, I decided to give them a call.

I spoke with Abbey, who was also confused as to why my tire size wasn’t showing any product matches. She placed me on a brief hold to consult with an expert, and it turned out they did have the right product. I purchased the chains and installed them for a fitting—and they worked perfectly!

Thank you, Abbey, for going the extra mile to find a solution and the right product for my needs. Great customer service!

Very happy with how easy it is to install these. I really appreciated the installation videos showing the different tire sizes - we got the right size first try for both of my cars. These are the only chains I will order from now on. Highly recommend.
by:
Tunnel View at Yosemite. Chains worked perfectly, but not quite as easy to install as the video would suggest. I made the mistake of pulling over into 3-4 inches of snow to put them on. The snow packed around the base of the tire made it very difficult. That's not something you encounter when practicing in your nice warm garage. But once on, the chains stayed secure, and the car handled and braked with confidence.

That's a pretty awesome shot you took, John! Before I read your review I looked at your pic and I can see what you mean how it would be difficult to put the chains on with all the snow packed under there. I'm glad that you were able to get them on and enjoy the rest of the drive.

I needed chains for my FWD Volvo up in the Catskills, NY. I have a dirt driveway, the FWD Volvo from 2017 can’t handle an inch of snow/ice surprisingly for a Swedish car. I searched for high quality chains and ended up here. I asked Josh questions before purchasing, he was so helpful. The chains are magic, tricky to install the first time, but now I can install easily. They work so well. They store back in their plastic box easily to place in the trunk. Very pleased.

I was looking to have snow tire chains for my upcoming trip to northern Wisconsin. I found these to be very easy to install as the instructions were very clear. I like that they come with a case to make them easy to store in my Ford Escape.

These tire chains got me out of jam recently when I had gone down a 1 lane thanks to massive snow road and there was no place to turn around. I put on the chains and was able to do a multi-point turn to get back down the road with ease.

I think this is the fourth pair of these chains I have purchased for various vehicles. I have had great success with these over the years. No chains are "easy" to put on but these make it about as easy as it can be. Once you are familiar with the process it takes only a few minutes per tire. The self-tensioning is the best feature. The storage box even has a hook and loop pad on the back so it won't slide around in your carpeted trunk or back seat. I got these for my '25 F150 Lariat. Our vacation home is at the end of a one-mile lane that is steep, snow covered all winter and usually icy in places from the sun. Snow tires and chains are a necessity for us.

I love these chains, and etrailer is the best! As a 69 yr old retired grandma, I work part-time at a ski resort. A few weeks ago, we were expecting 8-10 inches of snow/ice and I was scheduled to work. So, I put these idiot-proof, color-coded, self-adjusting chains on my Highlander front low profile tires and waited for weather. See photo. I worked my full shift, came out to ice/snow in dark, and drove safely home. Oh, and the carrying case comes with a folded plastic sheet, but with my old knees I added a foam pad!
by:
I have a 2019 Honda CRV and have never owned tire chains before so I dont have anything to compare these to but they are easy to put on and take off and they conquer a steep icy unpaved drive way in The Catskills perfectly. There are some plastic parts that probably should be metal. One of them - the tension hook - broke on one of my chains (see photo) and when I reported this to etrailer.com with a photo to prove it, they sent another set. So I am pleased overall with the service from etrailer.com but am only giving 4 stars for the product on account of the breakage. Also they rusted after one season but that hasn't impacted performance.

These are really easy to put on and take off. I have used them three times on my 2019 chevy colorado (4wd) to deal with high elevation mountain snow. After each use, I washed them, hung to dry and then put back in the truck. They are so awesome, I recommend them to others.

@Ann That's great to hear, Ann! Hopefully this winter hasn't been too bad for you.

I bought these for my 2022 Honda Odyssey for a trip to Colorado. We had to use them during a chain law enforcement through Wolf Creek Pass. They're easy to put on and take off and performance was spot on through snow pack and ice. Recommend getting familiar with them in clear conditions prior to use as its more difficult. I had no problems and would recommend for anyone, especially the novice.
by:
Well, I would say a little harder to put on correctly than advertised, but I called customer support and they helped me. Also watching all of the videos helped because each one was worded a little differently. Definitely would suggest one or two dry runs before you are in the elements. Important to realize to slide the plastic coated cable to the backside of the tire and center the chains after connecting the plastic coated cable and the small red hook. Once I figured this out I was able to almost perfectly center the chains (at least on one tire). On the other tire I couldn't get it perfectly centered (see photos). After about an 1/8 of a mile of very low speed driving it still didn't center but maybe with more driving at higher speeds it would. Also important to remember to have the yellow end of the chain on your right hand side beofore sliding behind the tire and making the first connection. One question I still have is how tight to pull the tension cable after you put it through the stop device. Every video seems a little bit different as to how tight you pull the cable by hand before connecting it to the tensioning device. As far as taking them off I tried four times to line up my car perfectly so I wouldn't have to drive over the chains after disconnecting them but this was not possible for me. So, with the plastic coated cable on top I just disconnected the connections in reverse and then put all the hooks and components off to the side and drove off/over the chains, which seemed to work fine. Will see how they work in the snow and ice but I'm hopeful they will do well.
by:
Very impressed! On a cement floor you can have the chains installed and snugged in under 10 minutes. Also an excellent increase in traction for a RWD van. Definitely recommend the konig XG-12's. Haven't installed while travelling but I don't think it will be very difficult.

We had a demo day a while back and I remember this brand being one of my favorites for the reasons you just said! Ease of use is key. Thanks for sending in the photos too! If you wind up using them - let us know how it goes!

Outstanding service! With an upcoming trip and recent snow storm etrailer helped me get my snow chains just in time for our vacation. Without the chains I would have been screwed. Communication with this company is impressive. The original chains I ordered would not have arrived in time and the sales team called me right away to find alternative solutions. Chains for 315/35/20 size tires are not easy to find. Really happy with my purchase. Thank you.
by:
Previously my only experience with chains was using cable chains on front wheel drive cars, where turning the wheels was necessary to ensure they had a good fit.

I bought these chains for my 2023 Kia EV6 with stock 235/55/19 tires. The instruction manual for the car says to put chains on the rear wheels and I was worried that getting chains on the rear wheels would be difficult. Despite never having used this style of chains before I was easily able to test-fit both chains with 15 minutes, and the chains fit very snuggly and didn't move when I move the car a cars length. Getting the inner loop positioned right is something that took a couple tries to get right, and I'm sure there might be a bit more room for improvement :)

I was slightly concerned about the chains damaging the rims or other parts of the car, but with the included spacers (not applied in the picture) I think this won't be a problem.

I'm taking the car up to the snow this weekend and if I use the chains I'll provide an update.

etrailer did a great job clearly communicating to me when my chains would arrive with no fuss.
by:
These chains are excellent quality and super easy to install. I watched the video and hold them out of the package line them up. Click them together. The tensioner works great. I rolled the truck back-and-forth. They are on and tight. It is well worth the money to have something high-quality that will work more than once.

Great Quality. Quick Installation and very easy to take off. Self-tensioning worked like a charm. I would definitely recommend them.

I bought these to use on my 2023 Rav4 TRD Off-Road OEM Falken AT Tires.

I highly recommend installing them at home a few times before heading up. Watching the etrailer videos on YouTube was also a huge help.

Fantastic, would buy again. Pulled out a couple jeeps with big tires. Sometimes the only thing that'll get you moving are snow chains
by:
Never used chains before. Bought these for my 2021 Jeep grand Cherokee. They works perfect! Tried them out in a trip to mammoth. Very rough conditions but they got the job die and got us through rough snow and ice. Best part they were easy to install. When chains required, took me less than 15 min to then in vs other struggling with conventional chains. Getting ready again for this upcoming winter. Thank you for the great videos and features allowing me to buy with confidence.

Jeep Compass
I bought these chains for my daughter who is moving to Chicago from California. The owners manual of her Jeep Compass warns about the limited clearance and these chains were perfect because of their low profile. I also bought these particular chains (I now own 3 sets) for their ease of use. Snow is not something that any of my girls are used to being from California's Central Valley and putting chains on was not something that any of them had the faintest clue about. These chains are so easy to install that my wife and daughter were actually racing each other the other day to see who could install faster.

My youngest daughter and wife are driving across county as I type this review carrying with them these Thule chains and I am confident that they and their Thules will handle any snow they encounter.
by:
Great tire chains. etrailer staff was so helpful on a few questions I had along the way.
by:
2017 Nissan Rogue
Went on quick and easily. I watched the installion video provided by etrailer. Exactly what you see, my only advice is be very careful to make sure the chains are spread out and completely untangled. If any links are crossed or tangled it won't go on correctly. Also l would recommend practicing putting them on once or twice. Once you have done that you can literally put them on in 5 minutes. The chains look very durable and quality materials. I got these for a predicted bad winter this year l will update after l get a chance to use them.
by:
2012 Honda CR-V
Quick shipping and great comms from etrailer. Practicing installing at home payed off in the wild. I was literally in and out of “pit lane” in 5 minutes! The chains were pretty quiet and performed well in 25 degree, snowy, icy conditions. Great engineering and solidly made.
by:
2014 Subaru Outback Wagon
Easy on after untangling. Safely up the mountain with no problem. Easy off. Found that individually bagging each chainset reduced tangling and eased storage in the provided carrying case. Hope this helps. Thanks etrailer.com for being there.
by:
seems like a great product, easily installed after watching etrailer video.

2004 Chevrolet Express Van
Two minutes. Yes, that is how long it took to put these chains on the tire. I didn't believe the other reviewers' reviews, but found out for myself that it's true. Everything is done from the outside of the tire. Brilliant design! Obviously, it's too early to tell how they will fare in the snow & ice this winter, but things are looking really good!
I bought two sets: one for our Lexus RX350 and one for our Chevrolet 2500 Express van. Both sets fit perfectly. They even supply gloves & a mat to kneel on when putting them on so as not to get wet.
Also, the chains arrived in two days...ahead of schedule.

(The pic shows the Lexus installation, but the Express van installation looked the same.)
