The tires size is fine, but I checked those wheels and I only see them in 01 and 20 offset. That's going to be your problem. 01 you have no chance, and 20 is probably also too far outside the fenders.
I have 275/70/18 on Method 18x9" +25 and they stick out just about perfect. A little past fenders, I am stock on AHC and if I am going fast off-road and hit something that compresses the front end fully they just touch a little bit. This only happens a "N" height once in "high" they dont contact even when actually wheeling seriously.
