Lookin sharp!
Im sure you intend on actually using those tires off-road, so how are you planning to prevent the rear tires from rubbing/bending/getting cut on the rear fenders on rough terrain?
Extend rear bump stops 2"?
Stiff rear springs or spring spacers that prevent up travel?
2" body lift?
Cut body?
When I fit 35" (317/75-16) to my G500 I was fortunate to have the european market wheels with low offset of ET63, which allows the rear tires to perfectly tuck up inside the rear metal fender openings without touching anything, no lift needed to fit 35" tires on a G!
I did use 30mm wheel spacers on the front axle only to regain some steering angle.
The same size tires on USA market wheels with offset of ET43 wil stick out just far enough to damage the fender opening when fully articulated in the rough stuff.
