2/1 lift on 2013 TRD OFFROAD largest tire size will take

Put a 2 inch spacer up front and 1 inch block in back and put 265/75/16 Wildpeak AT tires on it and although I like the ride for a daily driver I was considering going to some black wheels and a little bit bigger tire for a beefier look and maybe even adding spacers. Any suggestions on what is biggest tire can run on this setup without rubbing or with spacers. I don't want to go bigger than 17 wheels.

 

Seems like a lot of space left to work with. Can I go wider on tires or would spacers be ok to give it a wider stance? Any spacer suggestions or are there differing opinions out there on using them? Tried to post pic but new member... won't let me yet

 

Wheel spacers will make it rub worse at the back of the wheelwell when you turn.
