I have two sets of wheels for my 2500. My driveway is 1/2 mile long all up hill. Pure mud tires are all that will work in deep snow. And as abilene said the narrower the better. When I put my winter wheels on the truck I go ahead and put the chains in the tool box. IF you get stuck with the chains on your are really stuck. I have pushed fluffy light snow till I had to turn on the wipers on to see. If you run the mud tires in winter only they will last several years. They don't last long on the highway though. That is what the summer set of wheels if for.

God Bless, Louis
