Pewag Servo RS Installation Instructions

How to Install Pewag Servo RS Snow Chains

  1. Spread the chain around the back of the tire.
  2. Connect the cable on the back side of the tire.
  3. Pull the chain over the top and around to the front of the tire. Connect the servo device to the inner, tensioning chain with the top-mounted, dual hook.
  4. Fit the chain around the tire, making sure that the servo is in the front.
  5. Connect the inner chain to the outer traction chain at the bottom of the tire using the large red hook.
  6. Activate the servo device to ratchet the chain tightly into place.

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

185/60-15

  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 Servo RS Self-Tensioning Snow Tire Chains Installation - 2018 Toyota Corolla

Speaker 1: Today, on our 2018 Toyota Corolla, you're going to be taking a look at, and I'm going to show you how to install the Pewag Servo RS Self-Tensioning snow tire chains, part number PWRS73. Keep in mind, we'll be installing these on tire size 2055516. What's great about these chains is that you don't have to get down behind the tire to install them. Simply push it around, bring it up, and attach them. These are going to feature a diamond pattern, so they're going to give you more tire coverage than your standard ladder pattern. They're going to give you more grip in ice and snow, they're going to wear more evenly, they're going to have flat sides, so they're going to give you more surface contact.One great thing about these chains, unlike some of the other chains out there that require an extra tensioner, these are self-tensioning and self-centering.

These chains are a very low profile design, they're going to be SAE Class S chains, so they're meant for vehicles with limited wheel wall clearance. You're not going to have to worry about making contact with anything on the inside of the tire. One of the things I like about these chains is everything here in the center, it's got a plastic coating, so it's not going to damage your wheels. It's going to have color coded connections for easy installation, going to come with a nice carrying case, it's going to have a maximum speed rating of 30 miles per hour, it's going to come in a quantity of two. Now that we've gone over some of the features, let's show you how to get them installed.You're going to have a end like this that's going to have two arrows on it.

What you want to do is you want to pull that apart and slide it out. We're going to take this piece here, you want it towards the front of the tire and you want it facing down toward the ground. So we're going to lay our chain out like this, make sure we don't have any knots in it or any kinks. You'll notice a gap right here. This side, we're going to feed behind the tire, this gap is going to be on the center of the tire in the back.

We're going to take this end, slide it around, pull it around where this hook is coming out the side, and we're going to take each end, now we unlocked, squeeze it on our tire like this, put the rims together and push. Push that back behind the backside of the tire, then we'll start pulling everything around to the front.We're going to take our gray hook and gray chain, hook them together. Next, we're going to take our red connector at the bottom, and you'll see this piece here, it says open and drive. What you want to do, you want to push it to the open, and we're going to extend this. Pull it out.

We're going to take a red hook, we want to connect those two ends together. What you're going to do, simply push the red button to drive, and it's going to tension back up. Keep in mind, we are installing this on the front tire of the vehicle because this is a front wheel drive vehicle. You're going to repeat the same process on the other side. Once you have it installed, you're ready to go.That will do it for a look at an installation on the Pewag Servo RS Self-tensioning snow tire chains, part number PWRS73, on our 2018 Toyota Corolla.

Received the tire chains today. No adverse driving conditions to test them on. Will put them on tires this weekend - to check for fit and to practice installation instead of when they are needed. 594457

The chains were a great fit. It took a little while to figure it out, because I forgot to disconnect both the top and bottom portion of the chains before putting it on. 583240

Review from a similar Pewag Servo RS in Tire Chains


The little clips can get tangly, and the main clasp can be a pain sometimes to get it to stay clasped untill you get tension on it. But overall I have used them quite a few times and they work great. I would def recommend them over the traditional types. 468340

Review from a similar Pewag Servo RS in Tire Chains


Outstanding product! Very well-designed tire chain, quality components, easy to install, and terrific grip. I researched this purchase from some time and paid a little more for this quality product. We live in an area with very steep hills and quite a bit of snow and ice that goes unmanaged by the city. I figured these chains would be easy to install (I didn't look a the instructions before I took them out to put them on and had them on in 11 minutes), last a long time, not cause damage to my Lexus SUV, and provide excellent traction. They meet all my expectations. 469494

Review from a similar Pewag Servo RS in Tire Chains


The package came on time as you said it would! The directions were pictures with little text in a vinyl/plastic insert that fits nicely in the case. Watching the video helped a lot, should have looked at first before I installed one. I did it right but the video made it faster the second time! The case is compact and has a rigid separator plate that keeps the two chains separate. The service on the telephone was superb rate it a 10. This was reassuring since their are so many choices. The chains fit like a glove and now I hope I never need them! 344682

These are great quick and easy to install and don't require a roll over. Installed them at 0010 with a headlamp on a steep icy hill after sliding 75ft without them. 466930

Review from a similar Pewag Servo RS in Tire Chains


I have never been more pleased with a purchase decision than I am with these snow chains. They fit my car perfectly and were easier to install than I expected. If you have ever used on-ground cable chains, you know there are three connections that must be made, plus any adjustments to the tension device. With these chains, the connections are easy and the self-tightening tension device is impressive. At first I was not interested in this feature, but after using it I can appreciate how it will keep the chains tight and secure. I was also impressed by the design of the carrying case. I expected it would be difficult to replace the chains in the case once removed. Wrong. They easily fit back into the handy plastic case. Further, the chains came with plastic gloves to slip over your your hands (even with winter gloves) to keep your hands and lower arms clean. It's a bit odd to be so excited about a product that I hope NOT to use. But I drive to ski resorts all over the West and encounter chain restrictions often. Although I have all-wheel drive, I don't have snow tires and recent chain restrictions in Mammoth, CA require chains or 4-WD with snow tires on all wheels. Now, I'm actually looking forward to using the chains. I'm so pleased, I may purchase a second set for my wife's car. Finally, etrailer.com was great too work with. Their rep ( thanks Donna!) helped me find the right size chains for my wheels. Thanks so much! 335643

Their customer service is awesome!! They reached out to me via email as soon as they noticed delay and kept me updated on the delivery status, and also followed up after the delivery. We now have the chains we need for winter weather! We are very pleased to finally find the right snow chain for our tire size after looking around for 2 years!

  • 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.
