Tire/wheel question

I have a 2000 XLT 4wd and I am planning on lifting it 4"-6" and I came accross some questions. The backspacing on the Eagle Alloys Series 1179 that I want is, I think, 3 3/4". I am not exactly sure on the stock backspacing on the 16" stock rims I have on there now, but is the 3 3/4" going to make the tires stick out even further? I plan on getting the eagles mounted with either 33" BFG Muds or All-terrains. Also, one last question, would a 6" lift be enough to fit 35"s without trimming? Thanks

what metod of lift are you using? Superlift 4'' suspention, TT, Shackels, AAL, Body lift???? Also 3.75 on a 8 inch wide wheel is perfect.

I am using a 4" trailmaster suspension lift and maybe a 2" body lift.
