I'd like to see more photos of your setup. I've been considering going from the 3" Flexis I have down to the 222/223 setup. Since they support the same weight, it would just "in theory" help me lose us to 2" of lift.
The problem is you are getting 2.5" of lift on a 1.75" lift, and I'm getting ~4" of lift on a 3" lift. So I'd rather not waste the money if I'm going to only lose 1" MAYBE. Interested to see where it lands after you add the winch and do some driving.
I don't think you will have an issue with the tires, but it will be interesting to see. I had 35x12.5r17s on factory 4runner wheels and didn't have rubbing issues in the front. Rear was a different story until I got the panhard correction.
I would think if anything going with -25 would make your situation worse for scrub radius but there are a few guys who do it. Part of the problem is the 315s.
I now run 275/80/17s on 17x8.5 -10. And I wish I had 0 because it would fit in the flareless fenders better. But with flares I bet -10 would be mint.
Will get some more photos and measurements once it all settles, it has been less than a week and maybe 50 miles of driving.
I'm less concerned about rubbing on the flares, I can trim the inside of the flare. More concerned about rubbing on the frame and suspension because that's harder to fix.
Options in considering:
OEM wheels, 315s
Nomads, 17x8.5, -25, this might poke too much. They come in a 0 offset, but this puts the wheel closer to the frame/suspension compared to OEM.
Nomads, 16x8, -10, this is about 1/2 more poke compared to factory, would have great fitment, but not sure if I want to invest in 16" wheels.
In an attempt to mimic the 17x8.5, -25, setup with a 12.5" tire, I ordered some cheap 2" wheel spacers for my OEM wheel and 275 tire. That wheel has about 31mm more poke than OEM, and I'll gain 40mm of tire width (20mm on each side), which is 51mm more poke. Will experiment and see. Might be too much poke!
