Is there any way to single out my dually...cheaply

[dugweed]

I bought the dually because I was going to use it to haul RV trailers for Jet, but my situation has changed. Now I want to know if anyone can tell me an easy/cheap way to put wide (12.5) mud tires on the front and rear, for better flotation. I know the rear should'nt be too hard, just getting the correct backspacing, i'm worried about the front, and tucking wide rubber. Are the hub spacers removeable? if so what else would i need to do to fit srw wheels onto the front axle?

As far as I know you can remove the spacers. I would aim for at least 5 inches of backspace on the fronts and rears, should work fine. I am putting 53 inch tall michelin tires on my truck and will have to get new wheels to run them. I am aiming for that much backspacing as well. What tires are you planning on using?
