Installed 35" Tires

I currently own everything I spoke of. I don't need anything else. I just never tried putting the larger tires on my Tacoma, which is running 33.0"D and 12.2"W, manf. spec Yokohamas. My FJ has Icon tubular delta joint UCAs, which I believe are higher caster than the stock UCAs on my taco. Both trucks have CMC and a flattened pinch weld.
The wheel offsets are close, and I align both to max LCA castor myself and then rough align the rest- I tell the shop what to do on the rack and I watch it.
So, I thought I'd try swapping the bigger tires on my Taco, all other specs being relatively close.

 

Ok, I see what you meant by moving the FJ tire/rim combo to the Tacoma.
Yes, by all means give it a shot, absolutely nothing to lose.
