Largest tire on a 2015 Yukon with leveling kit?

[OUSux]

I am looking to buy a 2015 Yukon and want to level it and run the largest (tallest) tire possible. Does anyone know what tire that might be? Here is a pic of the 4x4 Yukon I am buying. What leveling kit would you go with?

Level depends on what you want, if you want max tire you can go even bigger

 

1.5" front

2.5" front plus 1" rear

Or bigger
