You will rub the front fender if you hit any dips when turning but, at the least, remove the air dam...it will rub on flat ground.
Any flex will be cause for concern...you'll know for sure when a rear fender is hangin in the breeze.
For comparison, on an un-lifted '14 2dr...
These tires are 33.5" installed...315/70-17 on 17x8.5 w/ 4.63 BS. Numerically, these tires are 34.4", the Grabber X2 is 34.8" and the X3 is 35". Take your own measurements.
The pinch seam on my '14 came relieved, no acute corner. You can make it out if you zoom in and "expose" the pic. Haven't hit the pinch seam yet.
I did start takin' out rear fenders when I flexed more than what one would encounter on the street and likely would have given the front fender and bumper a hard time if also turning while flexing.
I put on some PSC fenders. I rub somewhere when flexing...3.5" Lift yet to be installed. Bumpers have been replaced, no issues.
FYI, your tires will stick out beyond the fenders a good 1.5"...something to think about when inspection time comes. I haven't been stopped on the street with my 1.5-2" extension, yet. Inspection time gets the the WJ's tires/wheels.
