Note: To determine whether you can use snow chains on your vehicle, and how they may affect your ABS/EPS functionality, consult your owner's manual.


The pewag Servo RS self-tensioning 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 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 might want to get a chain with V-bar links that can bite into the ice you need to give you maximum traction.


These chains are among the easiest and fastest to install. Unlike other self-tensioning chains, the Servo RS have tensioning devices built into the side chains so there's no need to route additional tensioners when you install them. Just make a couple connections, move the button on the ratcheting device to "drive," and you'll be able to see the chains begin to tension. Because they self-tension more and self-center as you drive, these chains will give you 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 check 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 user 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 side wall 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 Snow Chains

Installing these chains is simple.
  1. Lay out the chains on the ground to make sure there are no twists or kinks.
  2. Slide the chain behind the tire and connect the ends of the cable, which will sit behind the tire.
  3. Connect the inner chain to the outer traction chain at the bottom of the tire using the large red hook, then activate the servo device to ratchet the chain tightly into place.
  4. Once all the connections are made, move the switch on the ratchet back to "drive." The rachet will tension the chains, then center and fully tighten them on your wheels as you drive forward, giving you a perfect fit.

Removing the chains is as quick and easy as putting them on. Just move the switch to "open," pull the cable to give the chains some slack, and disconnect.


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

Video Transcript for DIY 2008 Scion xB Installation for the pewag Servo RS Tire Chains

Hi everyone, it's Evangeline here at etrailer. And today we'll be taking a look at our Pewag Servo RS Self-Tensioning Snow Tire Chain right here on our 2008 Scion xB. So Pewag has a very unique self-tensioning system right here where they have the Pewag Servo. So let's say you're taking your vehicle out. You like to go camping, you like to go on adventures, but maybe where you're going requires a little extra traction on the road. What also may happen is you may be in certain states where they have requirements or certain areas where they require that you keep a snow tire chain or traction device in your vehicle or on your tires.

That's where something like this comes in handy. So let's take a look at this tire chain system. See if it's a right fit for you, right fit for your tires, as well as the right fit for your journey. So this is made of their unique Titan Grip construction. So that's basically a titanium steel alloy construction, which is gonna be helpful because one, it's corrosion resistant and it's extra durable compared to other types of materials used for tire chains.

Now, this is arranged in a diamond pattern. And what that means is it covers a little bit more of your tire compared to your traditional ladder style chains. As you go on the road, you're less likely to hear that that a ladder style chain would have, making for a smoother ride for yourself overall. Notice the different colors we have over here. That's pretty nice because then you have the color coded colors as you go along and as you put it together, it kind of helps you out with figuring out which goes where, it's a little bit of a complicated process though.

So I highly recommend checking out the install video at the end of this video, just to guide you through that whole process. Another thing about those chains is that they're also coated. So you can get the guards, they are included with this kit. They would go between your chains and your rims, helping provide a little extra cushion between the 2, once you have them finally installed. But also, if you're not wearing gloves, this is extra helpful because then you are not freezing your fingers off.

The links are shaped as square links. So notice how they have flat sides on each side that helps provide extra traction, especially with them being so small, that's helpful. Notice how you also have those grooves on the inside again, for extra traction. These are class S compatible. And what does that mean Well, you have a class SAE classifications, and if you need something that's super low profile, let's say you have limited wheel clearance behind your wheels and you just can't really get some extra room in there. This is what you need. You need low profile snow tire chains like these. Now I have these installed on our front tires. That's because per the owner's manual, this is the right place that we put them your Scion xB. I also have them on tire size 205/55R16. If you're not sure what tire size you have, you can find them printed right over here on the sidewall of every tire, those numbers will help you out with our etrailer.com fit guide, where you just input the tire size or even your vehicle, and we'll help you find the best fit for your vehicle. Now, when you get these snow tire chains, they come as a pair in this case. So this is a hard shell case. Very interesting looking, this is gonna be helpful as you have this stored in your vehicle, especially when you're in an area that just requires you have traction devices just in your vehicle, just in case, this is a nice storage option. Notice how we have these latches on each end, just pop those latches open, and you get access to your tire chains. So we have this divider on the inside. Your tire chains can get caught up in the divider or just untangle them and continue. You have some goodies as well. You have this plastic mat slash instructions. So as you are kneeling on it, you can check out the instructions. You also have this other goodie bag with plastic gloves, as well as replacement, replacement links, just in case. This hard case is especially helpful compared to other snow tire chains, because everything about this system is designed for long-term use. So if you're planning on using snow tire chains for more than one winter or more than one trip, this is kind of the way to go, because you do have that superior material construction, as well as like your corrosion resistance and all those different design features that you can reuse them. Instead of having to get a brand new tire chain. Now, this is a slightly more premium option. So we other, we also have other options right here at etrailer. Another low profile, very easy to install option is the Konig Self-Tensioning Snow Tire Chain. Not the easy fit, but the self-tensioning. It's a diamond pattern, which has, has kind of like a bunch of cable that comes down. We also have the Titan Chain Diamond Alloy Snow Tire Chain, which is a more economical option, requires a little bit more effort in order to install, but also very easy to install. So let's take a look at the install process of our Pewag Servo, just to see if it's the right fit for you. So what I recommend doing almost pretty much the moment you get your tire chains is to bring it out into your garage, lay it out on the ground and just take a look at it. First of course, make sure that everything looks good. Nothing is cracked or warped or missing. Another thing, or another reason I recommend doing that, is just that you get comfortable with the tire chain and figure out how it works. Especially since there's a bunch of different touch points. You wanna make sure you're familiar with it, before you're on the side of the road and have to install it in a hurry. This looks really good. Another thing I recommend looking at is making sure it's facing the right side. So notice how we have our flat portion. I, what I do is I have the flat portion facing up and the hook portion facing the ground. Because if you start that way, it'll mean the flat portion is facing your tire and not likely to puncture it, like the hook portion would be. With everything in the right place and ready to go. Just grab one end of it, I guess one half of it and feed it around the back of your tire. Once you bring it around this side, what I then do is I kind of set it up, so I just comb it out. So it makes a nice arc around our wheel that also helps make sure that this is not tangled and that each piece is on its correct side. Once that looks like that, you then connect your top points. Actually, this is a little tangled. We'll just flip that over, there we go. We'll connect our top ends, let's take a closer look at that. Just to demonstrate how it goes, this needs to fit into your latch. So notice how that just slides into it. So line it up like that, where you have your arrows facing each other. So I showed it down there just because your Scion xB has very limited clearance above its tire. So you wanna make sure you're kind of familiar with how that latch works, because you might not be able to see it super really well. Then you're gonna connect your other top connection, which is gonna be this red hook, as well as these red links, those go together and then you try to organize it. So everything is evenly distributed around your tire. Now notice how we can't really connect the bottom connections 'cause we don't have enough length and that's okay. We just have to make it. So we have our servo here. It says, drive on top, open on the bottom. So we're gonna push this towards open and that will allow us to bring this out. Just go ahead and get as much slack as you can get before you make your next connection. So now that we have a lot more chain length, we can then connect our bottom two red pieces and then go back up to the servo and then now push this towards to drive. There we go. So now that's in drive. You're pretty much ready to drive away. Don't forget to do the exact same process on the other side before you do so though. After installing both sides, what I recommend doing is just rolling forward a couple feet then going out and just double checking that everything is in place. Since this is self-tensioning, as it moves around, this will start tightening down even more, which is what adjusts it while you're on the road. But once everything looks good, that's it for the install, you're ready to go. And that was a look right here at our Pewag Servo RS Tensioning Snow Tire Chain right here on our 2008 Scion xB..

  • Tire Chain Recommendation for a 2009 Volkswagen Jetta
    Snow tires are a great option for a vehicle that will be in a climate that will see a lot of snow. And then having chains as a back up for when things get really bad is an excellent idea. First thing you will need to do is check the owners manual of the vehicle to determine if there are any snow chain restrictions. Next you will need to determine what size tires you will be putting on the vehicle so that you can pick out the correct chains to fit them. If you go with one of the standard...

    First if your Vredestein tires are snow tires you do not want to use any tire chains because they will not be effective. Pewag chains # PWRS73 will fit your tire size. If you are looking for some chains that you do not plan on using very often, I recommend come simple cables, # PW1030, with tensioner # PW100 (for passenger vehicle) or # PW99 (for light trucks).

  • Do Class S Tire Chains Have to be Used for a 2017 Kia Forte
    When it comes to tire chains you always want to reference your owner's manual for any specifications. It looks like the online owner's manual for your 2017 Kia Forte calls for Class S chains so you'll want to stick to that to avoid damage to brake lines or whatever it is that's causing the low clearance on the back side of your 205/55R16 tires. For your application I recommend going with the Konig Standard Snow Tire Chains # TH01221090 which are Class S compatible and give you a good,...
