First of all I have to say these chains work great. I live in Alaska and these things make it easy for me to get around in the snow in my 2WD GMC Canyon. In fact, I was able to pass places where I slipped less than others with 4WD and no chains. Runs fairly quietly once you're over 20mph, all you hear is a dull hum when on a dry road. At the same time, one of the wires got twisted after about 2 weeks of use. I'm still waiting to hear from the company if this is a normal problem or not. I would still buy them again because they just work and work so much better than regular chains.
