Awesome! Thank you so much for the detailed response!!Here is the side view of my truck with Westcott lift, +35mm offset Method 703s, and 35x12.5x17 Toyo AT3s at the manufacturer's specified 35 psi.

So with 11.5 tires and 35mm offset, picture my side view with the tire tucked inboard a 1/2 inch (your 11.5 would be 1 inch narrow, thus 1/2 inch per side. It would be a negligible difference.
If you are poked 10mm farther outboard with a +25mm offset, that's a bit less than 1/2 inch, so it should look essentially the same as my setup. You'll be a few mm inboard of mine, all else being equal. Again, negligible.
Prepare to be happy, you'll like the Westcott treatment!
