Have you tried full stuff and full turn at the same time? I'm pretty sure my tires will hit the front fenders under those conditions.

Yes, and I clear fine.
Looking at the math of my +60 offset with 1" spacers (effective 34.6mm offset), compared to your +50 offset RWs with .75" spacers (effective 29.1mm offset), shows your tires are about 5.5mm or 1/4" further outboard.
I have a touch of negative camber in my setup too. That might help buy a bit more space if you aren't already setup that way. I haven't rolled the front fenders. They look easier to roll and should be able to get some space.
For kicks, the tire shoulder of the common 285/75r17 or 285/70R18 tire with +25 offset are
- 6.5mm more inboard than my 35x12.5 +34.6 offset setup
- 12mm more inboard than your 315/70R70 +29.1mm offset setup
Would you happen to know how much “up” compression the rear tires attain during a complete double stuff/tuck?
Like does the widest portion of the sidewall pass the lip of fender?
I’m looking at my 35x10.5r17’s on 15 offset and wondering if they will double stuff.
By the math it appears they will…scary thing to “test” though.

On a square double stuff, 35s will definitely get its shoulder lugs into the tire well. In a dynamic condition, the body will move relative to the frame too. AHC does seem to manage and avoid g-outs well, but the tire will stuff and you'll know with witness marks. Looking at your setup, I do think it'll kiss, but should be okay. Your tires will let you know
Sounds like in the event of ahc catastrophic loss of pressure, I’ll be stationary. Would you tend to think so?
For anyone finding this thread and trying to figure out what offsets may work, I took some measurements.
As my vehicle sits in high mode, there is approximately 6.5” of space of compression before the bump stop (I’ve got a coil
Top spacer)…
So, I think, as long as there is 6.5” between the part of my tire that’s wide enough to hit the fender lip, I don’t think, in a double stuff/double tuck/catastrophic ahc pressure loss it would be possible to impact the fender.
I took some measurements and it appears there is 7” from the HIGHEST point of my 35x10.50r17 tire on 15 offset to the lip of the fender…
and 11.25” between the widest point of my tire and the outer lip of the fender
I think this means that it’s not possible, even with no fender rolling, for my 35x10.5r17 to impact the fenders in a double stuff situation.
The total width of the frame to fender lip and then theoretical “rolled” lip looks like 13.5”-14.5”
