23 Limited Eco Diesel 4x4 tire size

[Water xpert]

Just picked up my truck since the fuel system recall is complete.
I'd like to lift the truck which I think is not possible, so is there a leveling kit available to work with the air suspension and what the largest tire I can run without issues?

My 21 Limited Eco 4x4 has adjustable links on the front to level it, and had 295/70/18 that only rubbed on full turning when lowered in entry/exit mode.
