We really like the SC brand.. It aint plastic.. Our First set for all 4 wheels for our Trailblazer worked great. But we since got a NEW 2018 Chevy Traverse and we are due some heavy snow. The better your tires on a AWD the bigger the difference and we hope we don't need to put on the Cables.
our old set was still going strong since 2011. Make sure after Driving and you take them off to bring them inside and rinse them off and lube them up with a minimum of silicone spray. Then put them back in the bag for next time... and back in the car.
We have used Tire chains on different Cars and Trucks for years. I like the cables better at this time..
Unfortunately where we live we can't use the Chains with the Cleats anymore and Chains are not safe to use on a NEW SUV or Car now due to clearance in the wheel wells
NOTE: Make sure you Test Fit and Drive your Car or Truck to make sure they work right and are not hitting anything inside the wheelwell

This is a review for the Security Chain Company SZ447 Super Z6 Cable...

NOTE: when using any tire chain or cables like these. Test fit and give yourself plenty of time if this is your first time putting them on.
We test fitted these and spent 20 minutes the first time.. After that its about 4 minutes max per tire and about one minutes to release and take them off. Follow the video examples you can find on these. After a little bit of swearing the first time it should be much easier.

Did not fit. I even went to the manufactures site and used their tables, but the chain was too short. I even jacked up the car to pull the chains as tight as possible, so I returned and order the next larger size. There is a restock fee.
The next larger size is a little loos, but will work. The reason why I gave 1 star is because I believe the original chains were not the correct size. The chain quality appears good.
The chains have a nice feature that allows the chains to be installed without moving the vehicle, but that feature did not work on my car because there was not enough room between the tire and the wheel well. So I have to install the replacement old-fashion way (pull chains around the top of the tire and then back up about a foot to fasten them).
I have not had a chance to use them yet (Oregon missed all those blizzards that the rest of the county got), so cannot comment on how they ride.

I was in North Carolina this past weekend during a big snow storm. After watching the video and doing a dry practice, I had to pull out the chains and use them to get to a cabin. The installation was easy and took only a few minutes, everything seemed secure, and then while trying to climb a small hill with snow my tires were just spinning in place. I went back down and double checked that everything is installed per the video and instruction and tried again. Still nothing!! Tires spinning in place and the car going nowhere. Luckily I was able to find a store that sold chains nearby (nothing fancy regular chains) and when using those my car went up the hill no problem. I am not sure why this product got such great reviews but it just did not work at all. The best thing about this product was Amazon return policy.

I have a 2008 Toyota Sienna XLE (Front wheel drive) with 225/60-R17 tires. Unfortunately, Amazon seems to recommend size 139 for my vehicle. I am returning the size 139 because it doesn't fit. You should consult the SCC size chart. The SCC size chart says size 143. I first bought the size 143 from a craigslist seller and tried them on. They are very easy to install and the Super Z6 appears to be a solidly built chain. The tighteners are easy to put on as well. My concern came when I jacked my Sienna up and spun the wheel, checking clearances with everything. On the inside of the wheel, the circumferential cable just barely brushed the bracket and wiring for my front brake line and ABS sensor harness. It only did this on one part of the rotation, and other parts had several inches of clearance. If this cable wore through or tore out this brakeline/wire harness, that would be an expensive repair.

I slightly bent the brakeline/wire harness bracket to give just a smidge more clearance. I can't move it much. I then drove my car out on the driveway and backed it back into the garage and rechecked clearances. It seems to have balanced out just a bit more with about half an inch of clearance at the tightest part of the rotation. But still other parts of the rotation clear with several inches. I am guessing that driving will balance out the clearances.

This chain would be ideal if it gave a slightly longer inside circumferential cable with a slightly shorter outside cable. The clearances would easily not be a concern at that point. The width of size 143 seems appropriate, if only just a smidge too wide. My ideal chain would be slightly longer on inside and outside cables, with less width. But the SCC chart says nothing about actual chain dimensions.

I am going to run with the size 143 when I need to. Hopefully, that won't destroy my sensor wires.

My 06 Outback's owners manual says to never run chains. However, in California, you are by law required to carry chains in mountain/snowy areas. I don't want a ticket for failing to carry chains, so I'm left in an awkward position where California law requires I carry chains on a vehicle that tells me to not run chains.

I emailed Peerless chain company, and they told me they cannot recommend any set of chains for my specific car, because if the owner's manual says I cannot use chains, they do not want to transfer that liability to them. However, they mentioned that the Super Z6 chains require the least amount of side clearance of any of their chain models (6mm).

So I purchased the SZ139's (which are listed as a match for my car and the 225/55-17 tire). Turning clearance is fine, the biggest issue is how close the chains get to the strut and the brake line on the inside of the wheel. I didn't drive the car with the chains on at all - just installed them and lifted the car up to inspect them, so there's a chance the rubber tensioner would have helped pull the chains away from the brake line & strut. Who knows. I hope to never need them.
