Already searched...which wheel spacer - 285/75 on stock wheels

I'm putting 285/75/16s on my stock 16x7 trd off-road wheels. I need to order wheel spacers today, and I need to know the backspacing that will allow the least rubbing. I'm either going with Bora spacers @ .75", 1.00", or 1.25", that would make my stock wheel backspacing 4.5, 4.25, or 4 respectively. The most camber I can get out of my setup is 1.7 if that helps as well.

All that being said, I'd like to keep the wheels in as close to the truck as possible. Will the .75" spacer give me enough clearance?

I know we're talking about quarter inches here, but I really want to do this right the first time. Been researching different combos for 2 weeks, and I can't come up with any solid answer. Any help would be appreciated.

I also have a 2.5" front lift and 1.5" rear lift fwiw.
