No more stopping mid-drive to wrestle with loose chains. The pewag Snox Pro automatically tightens around your tires as you roll, keeping a consistent fit without any manual tensioning. When you stop, the system releases on its own, so taking them off is just as quick. For anyone driving through fresh snow or chain-law zones, this setup means less time on the side of the road and more confidence behind the wheel.

When traction starts to disappear on packed snow or light ice, the diamond pattern and 3.2 mm square links grab hold to keep your tires connected to the road. The smaller, evenly spaced links help smooth out the ride compared to ladder-style chains, while the diamond layout maintains steady contact for better braking and cornering. It’s a balanced design made for real-world winter driving.
Metal on metal isn’t what you want around your wheels. These chains include built-in anti-scratch bumpers that keep your rims protected as you drive. Whether you’re running alloy or painted wheels, those bumpers act as a cushion so you don’t come back from a snow trip with scraped edges.
Snow, salt, and slush can ruin a cheap chain fast. The Snox Pro uses nickel manganese alloy steel that stands up to rust and wear for the long haul. This hardened material keeps its strength and shape through repeated use, so the links stay reliable even after multiple winters of driving in harsh weather.
If your wheel wells don’t leave much room, these Class S compatible chains fit right in. They’re engineered for cars and small trucks with limited space between tire and bodywork, giving you the traction you need without rubbing or clearance issues. That makes them a solid choice for everyday winter travel where compact design matters.

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.

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

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!

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.
