What do ya'll think?

I took some measurements for wheels/tires and come up with this. These are rough measurements but it's pretty close. It makes sense though because I had a wheel on there a while back that had a 6" back spacing and the rim was about 2" away from the outside of the leaf spring. I'm running a Ford 9" rear end so that's why it more narrow. Sorry for my quick drawing that might not be exactly to scale but you get the idea. From this, if I wanted to run a 20" x 14" wide wheel I'd need a 6" back spacing. I'd imagine that would need to be custom built. And that doesn't leave me much room for tire buldge or at least as much as I think I want. I want a good amount of tire back there (no low pros) with about a 31" tall diameter tire. So am I limited to a 12" wide wheel or could I get away with a 14" wide wheel and still have room for some tire buldge (section width)?
