i used this to see how much further they would stick out. i put in 265/70/17 on the stock 17x7.5 wheels with the stock 31mm offset in the left box and 285/50/18 with the 18x9's with the 20mm offset in the right box and it says that they will stick out 21mm or .8 inches further than stock, so i would think it would be close, it might rub the fender just a little bit, but you could roll the inside lip of the fenders for a little extra clearance if you needed it.
