If you were going to go with 35s you would need to make sure you buy a lightweight wheel and tire combo. I have Nitto Trail Grapplers and they are very heavy. I have an auto and 3:73 and it's fine but I would go there if I had 3:21.
2012 JKU, 3.5" Rubicon Express lift, 35" Nitto Trail Grapplers, Pro Comp 17's, Smittybilt SRC rock rails, XRC front bumper with XRC8000 winch, Wurx rear bumper, and other stuff that's cool!!!
