pewag Snox Pro tire chains install so easily, you'll be on the road in minutes. Just pull the chains onto your tires and the unique self-centering, self-tensioning system tightens automatically as long as your wheels are rolling. The tensioners release when the vehicle stops, making it easy to pull the chains off quickly when you reach dry pavement.

Installation of pewag Snox Pro Self-Tensioning Snow Tire Chains

Grasp both ends of the red cord and pull outward to activate the self-tensioning system

1. Grasp both ends of the red cords on each side of the self-tensioning device and pull outward to activate.

Place the red self-tensioning system at the back of the tire and drape the chain along the face of the wheel to position the red bungee at the bottom of the tire

2. Position the red cord over the tire. Pull the cord to the back of the tire and tug the cord down, fitting it around the bottom of the tire.

3. Drive forward 1/4 of a tire revolution, keeping the wheels straight.

Once the bungee has been placed completely around the tire, pull on your assembly to make sure the chains are snug

4. Pull the rest of the chain around the tire so that the cross chains are positioned on top of the tire tread.

5. Repeat this process on the other tire.

6. Once the chains are properly positioned, drive forward. The Snox Pro chains will automatically tighten and center themselves as you drive. No manual adjustment is necessary.

7. The tensioners automatically disengage when the car comes to a stop. To remove the chains, you can simply pull them off or you can press the quick-release latch, which provides more slack in the chains to allow even faster removal.

Class S Designation

SAE Class S tire chains are designed for use on vehicles with restricted wheel well clearance. Certain newer cars, vans and small trucks, especially those with large, aftermarket tires, may require the use of Class S chains.

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 itself

How to Choose Snow Chains for Your Vehicle

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

Tire size on sidewall


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

Video Transcript for Pewag Snox Pro Self-Tensioning Snow Tire Chains Review

Adam: What's going on everybody. Adam here with etrailer. Today, we're going to be taking a look at the Pewag Snox Self-Tensioning Snow Tire Chain. What we have here is a relatively unique tire chain. They are going to be made of the same materials as most. Just a manganese nickel alloy steel construction.

We are going to have a diamond pattern. We have cross chains connecting those, so it's going to be great on the front wheels here to give us really good turning and traction. Of course, it's going to increase the traction, but this is probably going to be the bigger link that you can probably have with this wheel well clearance. It is SAE S Class certified, so you don't have to worry about that, but these are going to be one of the more aggressive chains we can put on this tire. If you're looking for ease of use, and also getting just the best amount of traction for the amount of space that you have to work with these are definitely going to be one of the best bets.If you're a big wheel guy like me, I want to make sure that my wheels are not going to get scratched or scuffed.

I try to avoid all curves, but whenever we're putting on chains sometimes it could scratch it just like if we did hit a curb. With this all of the components around our wheels is going to be either plastic or coated in a specific coating that's not going to scratch your wheel. If you have aluminum wheels, if you just have your OEM wheels like this that you want to keep nice and pretty it is going to be able to allow that. Some of the other chains don't, and these do, and that is definitely a plus. Another plus I like about these chains is we don't have to grab a rubber tensioner separately.

We have a little tensioner here, which is going to keep everything nice and tight.These chains do come in a pack of two, so if you plan on just putting them on the front tires you can just grab one, but if you play it on putting them on four, you can just grab two sets of these. They come in a nice little carrying case. I like this one better than any of the other ones that I've had, because it's small, it's got good zippers, it is easy to carry, and it's got nice little pouches to get everything all stored away. This is a great bag. And I like the bag.

Even if during the summer months, and you're not using them, I'd probably use this for something else, because this is a nice bag.But what's also nice is how quickly we can get these off. What we've got to do is press this little tab here. It's going to release that like that. Literally all you got to do is just give her a good tug. Once we get one little section going it's going to be easy to get it all undone, because it all just kind of follows suit. But other times it really wants to stay on there, which isn't a bad thing. You don't want the chain to fall off whenever we're riding down the road. Just work your way around. There we go. Then now, all you got to do is just roll off of them, put them back in the case, and we are ready to go for next time. Well, everyone that just about does it for our look at the Pewag Snox Pro Self-Tensioning Snow Tire Chain.

Average Customer Rating:  4.5 out of 5 stars   (49 Customer Reviews)

These diamond-pattern, square-link chains provide excellent traction in snow and ice. Just loop the chains around your tires to install them, and they will automatically tighten as you drive away. Great for vehicles with limited wheel-well clearance.


Got me around in a civic in hilly country in snow with little problems. Got the hang of putting the chains on after a couple of tries. Great product.


Product boasts being perfectly easy to pop on and roll away but the bungie is rather stiff and somewhat difficult to pull to the back of your tires. Once you DO get the red cable to the back, you need to perfectly align the chains to the top surface (treads) of your tire; otherwise, the bungie will pull and tear, ultimately breaking the chains inside of them.

That said, I do still recommend this product - when properly installed, they are very sturdy and get me out of my steep driveway like a champ. I also highly recommend etrailer (their customer service is awesome and they are very understanding when it comes to product flaws or user errors).


This review is based on a one time use, (a three days of heavy snow in the mountains actually). These chains were a little difficult to install on my first test, but only took a few minutes on a dry sunny day before heading to the mountains. When the environment turned wet and cold, my hands took a biting even with heavy duty globes, I struggle a lot, but I managed to install the first one in 10 minutes and the second wheel in about 15 or more minutes. Once in placed they worked very good and had excellent traction and turning capabilities. These chains seem to be made of a high quality built and tough materials and hopefully will last a long time. The shipping was fast and product arrived in good condition.

2014 Volkswagen Jetta SportWagen

I am from Austria. I used Pewag snow chains all my life. These are easy to mount, very easy actually. Highly recommend!


The good news: I have not needed to use them so far this year! They are in the trunk just in case. I am happy I just have a set of quality chains, IF and when I need them.

BTW, these guys are heavy! They could be boat anchors.




The ETrailer website was easy to use and the order filled and shipped without delay. I can't comment on the snow chains until I have an opportunity to use them.


Review from a similar Snox Pro in Tire Chains

Fit snugly. Will be a little difficult in the snow but with a pair of gloves on it is doable. The red plastic rim protectors would protect rim from metal on metal contact. However, with my M-sport rims and Pirelli Cinturato P7 tires, the red plastic doesn't even come into contact with the rim due to the extended lip of the tire...but this does mean that the chain touches the outside surface of the tire--see pics. A little off putting scarring the sticky looking surface of the tire...but it is inevitable.

On the inside of the wheel/tire, my concern was contact with the knuckle, strut, end link, stabilizer, etc. It does get close to the stabilizer end link, but doesn't pictures are shown before self centering while the spacing to end link would only get greater as I installed in worst case scenario to compare.


Review from a similar Snox Pro in Tire Chains

I drive a 1996 Corvette and have for the past 20 years - year round. And that makes driving near impossible in Connecticut winters and hilly terrains. Until I got my Pewag chains. When the snow accumulates, on go my Pewags and away I go. Snow covered roads, no problem, up and down hills, no problem. I can put my Pewags on both tires in less than ten minutes and I am good to go. Great product! I highly recommend Pewag chains.


Review from a similar Snox Pro in Tire Chains

I got to test them out for the first time after 4 inches of snow going up a long, steep gravel road full of switchbacks and ice patches in Blue Ridge Mountains. They performed wonderfully and were pretty easy to put on. My only concern are the blue plastic parts that could be a weak point.


Review from a similar Snox Pro in Tire Chains

Noah walked me through all of the different snow chains for our S.U.V. Very knowledgeable. Found our several things that I really needed to know to get the right ones. Very happy with the result.


Review from a similar Snox Pro in Tire Chains

By design the installation and removal of this set of chains was quick and easy not to mention the great handling on the 2inches of compacted snow. They performed well on the ice as well once we were at a lower elevation level coming out of Mammoth.

When traveling through Mammoth these chains allowed us to go through ICE and snow with ease in our 2005 Toyota family minivan. They were more convenient to store and install than others I’ve tried in the past. Even though everything wears out over use this set is still holding up well and was worth the investment.

Review from a similar Snox Pro in Tire Chains

They are easy to put on and very durable, glad to have them anytime snowy conditions hit in our So. Cal mountains!


Review from a similar Snox Pro in Tire Chains

Purchased these chains for a trip to the snow and for future use after buying a new vehicle. The chains were received promptly in a well designed carrying case, with a mat, gloves, and instructions for mounting the chains. I haven't had to use them = a Subaru Forester is a great AWD vehicle and handled some pretty dicey conditions with no issue - but carry them and feel confident I can mount and dismount them quickly. Instructions are clear and simple to follow.

Still havent used them but they are a great security blanket

Review from a similar Snox Pro in Tire Chains

Easy on, Easy off. Haven't driven into the really rough stuff but works well for places that have chain requirements. I wanted convenience and this product delivers.


Review from a similar Snox Pro in Tire Chains

I was concerned about using chains not prescribed by Volvo when I read forums about what chains to use. I purchased these with the hope that I would not have to find out if they were the right chains.

It snowed heavily in Tahoe and I had to use them on my AWD XC70. They were perfect. The chains did not cause a problem with the lack of clearance in the front wheel well.

Putting them on took some strength to stretch the bungee around the tire. Taking them off was completely easy.

I would recommend these. The price is high, but worth it for the peace of mind that I won't damage my car's front steering or suspension.


Review from a similar Snox Pro in Tire Chains

I have just purchased these chains for my 2015 forester. In trying them out in my warm driveway, I have some observations.

1. First of all, it is great to not have to close some link in the back of the tire when installing chains...YAY!.
2. The carrying case is nice but was missing one zipper tab
3. In putting them on, the bungee cord is not that easy to stretch so the installer will need some arm strength to get it into place.
4. Once on, they were easy to get off.

Overall, I like them

Review from a similar Snox Pro in Tire Chains

They were not easier to put on, and they promptly came off all together. I would have done better with a standard old school chain.


Review from a similar Snox Pro in Tire Chains

My first attempt at putting on the snow chains was easy, but I could NOT remove them. I looked at the customer reviews and everyone said removal was easy. Needless to say, all the reviews came from men. Becky from customer service suggested that the quick release latch be at the top of the tire during removal. This did the trick! I now have a set of good quality snow chains that I can put on and take off by myself when I take my grandkids to the snow. Etrailer has super fast delivery & great customer service!


Review from a similar Snox Pro in Tire Chains

Put these chains on before you need them! Once wheel well gets packed with snow and road salt, putting these chains on is not pleasant. Once they're on, they work great. Drove up to 25mph down a very windy mountain road with high confidence. They popped right off when done and stowed away perfectly. I'm very happy with my purchase.


Review from a similar Snox Pro in Tire Chains

Haven't had to use them. Bought them because I had crappy stock tires on my AWD Subaru, got these specifically so that if I did have to use them they would not scratch my premium wheels.

I now have better tires, probably won't ever need them but have them just in case chain control is absurd.


Review from a similar Snox Pro in Tire Chains

I mounted my Pewag Snow Chains (PWSXP560) today on a dry run. I was very impressed with the method of installation, as well as the ease of taking them off. I purchased them because of a very bad experience I had with chains previously. I was very uncomfortable driving in conditions that would require chains. With these chains I have confidence in using them should conditions require them.


Review from a similar Snox Pro in Tire Chains

I have used them a few times now on snow and ice and they are great! Definitely worth the money! They are easy to put on and take off. Would be very helpful in emergency situations. Putting them on takes a bit more time than taking them off, but still just a few minutes. I was very surprised by how much traction they gave me in snowy and icy situations. These chains seem like they are durable and reliable. Definitely recommend! Also they delivered fast, which was good because I ended up needing them right after I got them.


Review from a similar Snox Pro in Tire Chains

Easy to install and take off in minutes


Review from a similar Snox Pro in Tire Chains

I can't give a complete review because we haven't tried them yet. Need to see how they work in the snow first but my first impression is a little less than satisfied. I have used may snow chains in my life but the material of the chains don't seem to be very strong and I don't know if they will hold up to the road test. I'm not feeling very confident that they will last one use. I bought these chains for my daughter's car and I love the ease of installation. I hope they get her home during her winter break from college.


Review from a similar Snox Pro in Tire Chains

The description of these tire chains indicates they are easy to install but if these are easy to install I would not want to install difficult chains. Thus the four stars. They are made of good quality materials and do seem to self center and seem to do the job.

  • Recommended Snow Chains for 2017 VW Golf Alltrack with 225/55-17 Tires
    The 225/55-17 tires are bigger than the manufacturer normally puts on the vehicle. If you have these tires, you will have even more limited clearances so I recommend only using the Konig Premium Self-Tensioning Snow Tire Chains - Diamond Pattern - D Link - K-Summit - Size K44 # TH02230K44. These chains require no inner clearance as they only ride on tread portion of the tire. I've linked a video of this to assist. The chains should be installed on the front tires of your 4Motion system....
