Will this work?

I want to put a 6 in lift on my pickup. I have a 99 F250 SC LB. I was wanting to put 37x13.5 Toyo MTs on 20x10 wheels, now here's the question: will these tires and wheels fit with these wheel specs

Backspace = 4.52 in
Offset= -25 mm

I just wanna also make sure the bolt pattern I need is 8 on 170.
If this will not work, please give me any info needed to complete this modification.

Another question: will I be able to keep my airbags?

The BS is correct. 8x170 is correct.

Depending on how you lift the rear you can keep your bags..or mod them for lift springs..

How bout the offset? And can I clear 37x13.5?

Offset doesn't matter BS does or you will rub the springs. I would run a 8" lift.
