2000 7.3l cclb f350 4x4 srw. Leveled with x codes and and a tuff country 2.5" mini spring pack. Right now I've got cooper stt 315/75r16 on the stock 16x7 lariat wheels. They rub at full lock and I'm so over the whole 50 point turn lol. So, today I ordered some Mickey Thompson classic 3's 16x8, 4" backspace/-12mm offset. I was assured over and over that they wouldn't rub and I'm pretty confident they won't but, wanted yalls opinion. Thoughts?? Thanks yall.

 

Bump......

 

On my 2003, I had been running 16x8 wheels with 4.25" backspacing and 315/75R16 Pro Comp Extreme ATs with only a 1" lift in the front (much like your mini spring pack only not as much lift). I had a very slight rub on the leaf spring at full lock in only one direction. With a quarter inch less backspace and the extra 1.5" of spring pack between your main leaves and your axle, you should not have any spring rubbing issues. You may want to watch the fender and/or front bumper since you are pushing the outside edge of the tire about 0.75" further out from the ball joint line, but I would imagine you should clear everything just fine.
