It seems as though anything over 33.2 inches in diameter will require crash bar modification or some configuration of a lift/level+spacers. Not by much though it appears on other threads.
Yeah, it's going to be tight. First thing you could try is to loosen the bolts on the front crash bars and push them as far forward as you can. You might possibly have to remove them. My biggest concern would be with your knuckles up front. My tires (Falken Wildpeak 275/70R17) just clear the knuckles. I'm leveled too.
