if you live up north you have 4x4 and chain on all fourWhy would you install chains to wheels with no power to them? Did you ever watch Ice Road Truckers? Did you ever see them put chains on the front, Non Drive Power Wheels? Not. M.B. put that in the manual for liability reasons like a lot of manufacturers have had to do for people who do not know better. Chains are for loss of traction not steering. If you have lived up north for any extended period you would never see chains on the non powered wheels.
