That's interesting. Interpolating for the 34" tires we're discussing means a 5" back spacing. Since the tires we're discussing are about 11.5" wide, that's another 1/2" so we could go with a 5.5" back spacing. If I had 8" rims rather than 9" rims, that picks up another 1" on the outside. So 5.5" back spacing with 8" rims should put the outside edge of the tire close to the outside of the fender and prevent the mud splashing all along the side of the Jeep and the tire contacting the fender lower lip. Compared to my setup with 4.5" backspacing and 9" rims which puts the outside edge of the tire about 2" beyond the fender.
Yeah, a pic is easier to understand.

I have a 2012 JKUR with a Mopar 2" lift. I have the 285/75R17 BFG MT's on 17x9" wheels with 4.5" backspacing. And 4:10 gears, auto trans. I like your idea of 8.5" wheels (or even 8") with 5" back spacing. I don't do severe articulation but haven't had any rubbing issues. I don't like the tires sticking out about 2" beyond the flares. Don't like the look. Don't like the dirt slinging all over the side of the Jeep when I hit a puddle or dirt from a dirt road after the rain.
