Security Chain Super Z6, SZ135, Cable Chain for Passenger Cars, Pickups & SUVs

fast and easy to install, only tried in the garage, did need to jack up the rear of car some, as there was not enough clearance to reach into fender to connect rear.

My tire size is 225/65-17. Amazon's size guide says to order SZ135. These chains are too small. Another vendor has an online size guide that says SZ143, which is larger. Since Amazon made me order the wrong size, I cannot guarantee that SZ143 is correct. But SZ135 is incorrect.

I bought the chains from Amazon and decided to try them on before I leave on my ski trip. Thanks God I did, because the chains didn't fit. I'm glad I didn't discover this on the road when I actually needed them.

Before I ordered, I checked what the correct size for my tires (205/50-17) is. I checked both the manufacturer's web site and the guide on Amazon's web site and ordered the recommended SZ127 model. Amazon sent me the correct chains, my tire's size was listed on chain's bag, everything was perfect but the chains were too small and they didn't fit. They were not even close to the correct size - maybe close to half the size of my tires.

If the company cannot get the most basic thing for tire chains right I highly doubt they are competent of creating a quality product. I would have given zero stars but Amazon doesn't let me.

This is third set of cable chains from SCC that I've owned. The first two were for my pickup and my wife's previous car. All of them have worked great on snow and ice. They are the easiest tire chains to install that I've ever had. I've learned how to install them without having to move the vehicle and still stay pretty clean.

Finally forked over for these and wasn't disappointed on two trips up to Mount Hood this week. Handled beautifully in the snow. So happy we got these -- I think they may be the only chains recommended for Toyota Siennas, which have a very small amount of space between the tire and the wheel.

First-tire set-up took about 15 minutes, but each subsequent tire/installation was less than 1 minute. (Practice at home before you have to do it in the cold wet snow.)

Note: you'll be doing lots of tire-hugging to install these -- be sure to get a pair of thin, warm, waterproof gloves, which will help make installation in the cold just that much easier. Also can't hurt to have a mat to kneel on. And keep a flashlight handy for spotting the connecting-point in those otherwise dark, tight wheel wells.
