i am running dz101 245/40/18 on all four, 18x9.5 +38. My rear bumper (near the black circle clip) was rubbing, it wore down after about 50 miles and i no longer rub. I plan on intching up to 255 and letting it rub down again and hopefully i am able to squeeze in a 265 at some point. My front is clear, but i am probably roughly -2.7 - -3.0 camber on front. rear is -2.0. My fender line is just a few MM lower than my rear tire height.
Which hankook are you going to run? look up the contact area and see if it is wider than mine. My situation however was right at the edge between contact area & sidewall so it will likely rub in the same spot for you (it is pretty common some just sand it down by hand prior to install). And yes you will be stretched on that size. My "rim guard" separates from the face of my wheel, and my tires dont look anywhere close to square.
