I didn't have any clearance issues with the stock tires and stock ride height.
When I put the Old Man emu lift in I had to use an adjustable track bar to re center the rear axle. Shifted right 1/2" with the lift. JKS track bar corrected it.
I use 1.5" wheel spacers now with the 35" tires and they don't rub at full turn or full stuff.
