eh i wouldnt think they would rub much worse with a 16X10. with 3 inch body lift and 2 inch tt and 2 inch shackle?
Suit yourself then.
Normally the 10" wide wheel will have same (or close) backspacing as the 8" wide wheel. Meaning that the extra 2" of width is all on the outside.
The rubbing occurs when turning. When you turn the wheels, that extra 2" sticking out there moved the tire forward and back MORE inside the wheel well, making more contact on the back of the wheel well.
Not to mention, the rear tires will not tuck under the fenders as well, sticking out so much further.
Plus you'll be putting a lot more stress on the wheel bearing and balljoints with the extra 2" of leverage.
The torsion twist is going to make the truck ride rough, leave little to no down travel in the front end, and won't do a whole lot to help clear tires, simply because of where they rub. If you use the thing off road at all, you'll still compress the front to full compression and rub.
But it's your truck

Plus I think the 8" wheels look better. Here is mine with 15x8's, 33x12.50's, 3" body lift and warrior shackles. Best I have for a side shot showing where the tires sat.
