When the roads get slick, the diamond-shaped pattern on these pewag Servo RS chains keeps steady traction from every angle. The square links dig into snow and ice for dependable grip while still giving a smoother ride than ladder-style chains. Even in deep snow or light ice, they stay consistent so you can focus on driving instead of slipping.
Once you flip the built-in ratcheting device to “drive,” the chains automatically tighten and center themselves as you roll. There’s no need to pull over or recheck tension—just make a few quick connections, drive forward, and the system gives you a snug, even fit every time. It’s a real time-saver when you’re putting chains on in the cold.
If your vehicle has limited room around the tires, these chains meet SAE Class S standards. Their low-profile design gives you the traction you need without eating up precious wheel-well space. It’s the right setup for modern cars and crossovers that can’t handle bulkier chains.
Each link is built from high-quality titanium alloy steel that stands up to wear and rust. The 3.5 mm links give strength without adding weight, and plastic bumpers protect your rims from scratches. When the season’s over, the durable storage case keeps everything organized and ready for next time.
You just drape the chains, make the connections, and go. When it’s time to remove them, flip the switch to “open,” release the cable, and lift them off. Compact and straightforward, these chains pack neatly in the trunk so they’re always ready for those snowy mountain drives or sudden winter storms.
These chains fit the following tire sizes:

Having used them but a few times on a vehicle that surely doesn’t belong in the snow I’m amazed. Not by the performance so much but again in the ease of installation. As to performance, chains are chains in that they work as they should. Cable traction devices do not and do not last for beans. It’s perhaps why you see so many pitched off onto the road or someone off the side trying to unwrap them from their axle. These not only do the job but adjust immediately, stay on and take but a few minutes to remove.

These chains have held up really well. Got the installation process, in stormy snowy conditions, down to 5 minutes or less per wheel. I dont like to rely on the self-tensioning feature so I release the servo and tug on the cable to make sure that the cable is retracted and tightened as much as possible and then I let the self-tensioning feature do its job when I move the vehicle. These chains have gotten me out of my street and to work before the plow comes through the street. Definitely recommend them!

That is a shame to hear that the clip for the tensioner was not unlatching for you. I have gotten in contact with some of our install team to check this out, and we have found that there are times when the red notch on the tensioner will get stuck due to the amount of tension. So what you can do, is squeeze the tensioner to release some pressure off of the red latch. Then push the red button to release the chains.

You mentioned that they were not a fit for your snow tires. I have a few questions that I would like to ask. What is the size of the tires? Would you be able to send a picture on how they do not fit? Did you reach out to Pewag?
Do you have a question about this Tire Chain?

In the year that I have owned these, I have used them exactly once and I can say that under conditions it can be a bit tricky and at times frustrating. I suspect that additional installations on the side of the road will improve the time and patience it takes to install them. Removal was fairly simple, but putting them back into the case can be a challenge - Do note, they will scuff up your rims, but that can be polished out. One key take away: Everythings easier on a dry run literally dry... lol
