I had one of the tire guys say that I should take off the outer rear tires and run on the inside tire on my 07 Dually. Is this a good idea?

 

IDK about that one
I don't think it will make a difference that is the joy of owning a pick up truck man sliding around in the snow. Since you don't have 4wd its going to be worse on you with the new truck.

 

I've never heard that. I've always heard you might need to put some more weight on the back tires. Some folks put sandbags in the back to get more traction.

 

It makes sense. More weight per square in of road contact will prevent slipping more. Kind of like how compact cars don't get traction in snow either. It will look a little wierd though.

 

they look really strange with insides only, what i would do is get some sand bags or something of that nature to add a little more weight, and air the tires down a little for more road contact, as long as your not hauling anything real heavy, 35-40psi is more than enough with the duals do drive on, and will give some more traction

 

Weight in the back helps immensely. Get at least 500 lbs in there. The reason front wheel drive cars are better in the snow is because of the weight form the engine and transaxle is over the drive wheels.

 

Well I put 600 lbs of Tube Sand in the back over the axles and bought some pretty aggressive snow tires and got them studded. Mastercraft Courser MSR Hope this helps

 

Its snowing and streets are icy here in Chicago and I've not put it in 4wd yet. most likely i wont put it in I don't have weight in the back. Its all about how you drive in the snow.
