It's really annoying that in the photos of all these chains there are always 5 or 6 pieces on each tire and you only have 6 pieces. I have never bought American chains that would not be enough for 2 tires. You don't want to be driving down a difficult road with just three. Not suitable for car or driving. However, I bought them to see how well they work on the beach. We have a rear wheel drive van that I stranded on a beach. One can even help with this and that's why they are easy to put on.
