Should you use 2 or 4 tire chains on an all-wheel-drive car?

Answer 1

There is nothing that says you have to use 4, it is only a matter of traction and that is all. Expert installers in California (they hang on the side of the road and help people w/their chains, and they are even licensed/registered) told me on a Jeep Liberty I had rented to keep them on the rear wheels, that it usually works better. They did give me a choice, they said that some people just prefer the front, but it is harder to drive when you hit dry stuff. But putting them on all 4 is just for better traction, so if really bad conditions, do it, but don't do it because of things like why you don't run different size tires, you don't have those problems as you are usually on slip-ground anyway, and you can't drive fast with them on.
