These chains use 3.2 mm square links that dig into snow and light ice, giving steady traction when roads get slick. The diamond pattern spreads that grip across more of the tire, so instead of that rumbling “ladder” feel, you get smoother rolling and constant contact on packed snow or steep grades.
Once you make the quick cable and hook connections, flip the switch on the built-in ratcheting device and drive—each chain automatically tightens and centers itself for a perfect fit. There’s no need to stop mid-drive or re-adjust. The servo system keeps tension steady, so you can focus on driving instead of crawling around in the snow.
These chains are built for vehicles with limited wheel-well space. The Class S design means they fit tight areas where bigger chains won’t, with only 1.46" (37 mm) clearance above the tread and 0.59" (15 mm) at the sidewall. Plastic bumpers along the chain protect your rims from scuffs, keeping your wheels looking sharp even after repeated use.
The high-quality titanium alloy steel construction stands up to harsh winter conditions. It won’t rust easily and keeps its strength through repeated freeze-thaw cycles. Dry them before storage and they’ll be ready to go next time the snow piles up.
Each set includes two chains packed in a durable storage case that stows neatly in your trunk. Lightweight and compact, they’re easy to toss in before winter trips so you’re ready any time snow catches you by surprise.

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!

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

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.
