Better go as narrow as you can in the front or those are going to rub big time. I'm effectively running 16x8 -9.5mm offset with 245 tires and they hit the front corner of the flare in harder corners. I actually broke the corner of the flare off the car. I'm pretty sure 265/40 is what most people are running in the rear. If you've already got the tires you might as well install them an see how they fit, but I'm doubtful. There is less than 1/16" at normal ride height between the flare and the tire at their closest point when turned.
