Jrod - I dont have a definitive answer for you. But, here is my best guess....
When looking at a BFG AT -
295/75R/16 = 33.2" height
285/65R/18 = 32.7" height
I run the 295's above. I barley rubbed the back of the wheel well at the pinch weld and ever so slightly at the top of the wheel well in full compression. The top was experienced when traveling at high speed in the desert.
The tire you are wanting to run is about 1/2" shorter in height and if you do rub at the back of the wheel well, it will be so slight that all you would need to do is trim the plastic at the weld. Look at the bottom of the wheel well and you will see where I am talking about.
Good luck!
