Lifting a 2018 Quadra Lift
 

I just bought a new 2018 GC High Altitude which comes with Quadra Lift. Stock tires are 265/50R 20, I want to run Nitto Ridge Grapplers. Does anyone have experience running these tires (265/50R 20) on this Jeep. Will they fit? The Nitto's spec out at 0.47" larger in diameter and .001 wider in section width. Alternatively I could raise the Jeep using adjustable arms linking the height sensors to the suspension, does anyone have experience with these arms and the effect on ride and long term reliability of the air bags with more pressure in them? Thanks
