Backspacing Question

[CJS]

I'm about to be at about 3.5" of lift w/ 32's and I need to know what BS to run. The tires are 32X11.50's (15" rim) and originally I was figuring on 4.75" of BS but I am worried about the tire always hitting the control arms. I was planning on running 4.75" in order to get the tires to tuck into the fenders under full compression but now I am worried that they will be rubbing on everything else. If anybody could offer me some good insight I would appreciate it.

4.5" is good to, it's only a 1/4" Difference. I have 4.75" with 33x12.5 and I like it. They only rub the LCA's when really flexed up, but normal driving clear just fine.

You may want the 4.5" also if you plan on changing your steering geometry, like over-the-knuckle.
