Chain up question

Outside tire on the rear duallies. I"ll look for the site on the WSDOT web site. I know the requirements are posted there.

I was raised to use chains on a 4 X 4 front tires and use the 4 X 4 feature. let the front wheels pull you through the snow. if it's that bad, I would pull over and sit it out in the camper and wait for the plows to clear the road. I was just reading on the Oregon web site and they state have traction tires or carry chains. BUT if you have a 4 X 4 you must have true traction tires, not just highway tread.

Four wheel drive vehicles aren't required to use chains in ordinary circumstances, but MUST carry a set for at least one set of wheels. Position not specified, as you already found out. link to WAC

My brother the dually owner carries a set for the front two- says the steering boost is what's needed. Plus it's easier to put the fronts on!

There are special chains for the rear wheels of a dually.

Are you asking whether you put them on the inner tires or the outer tires? Or front vs rear?
