As the last post said, they will have to be "cable chains", not actual chains. Also, if you have traction Control, you must get cable chains made for that else the STC will go nuts. The cables are kind of like a series of ">'s" in the direction of the tire roll, not a series of "I's" perpendicular to the sidewalls like regular cable chains. A number of manufacturers make them. I can check what mine are when I get home from work.
