What rough country told you is incorrect. In the video above, the Arkon Lincoln 20x10 -25 offset, w/ 4.52 backspacing didn't fit. The Method MR701 17x18.5 0 offset, w/ 4.75 did fit.
Also, they make the Hoss 2 in a 0 offset, that has 5.0 backspacing. I'm wondering if that is what they're running on the white AT4 on their website (12mm of offset difference is less than 1/2inch of width).
edit* upon further looking, they're definitely not running the 0 offset. So IDK lol
