To give you some extra data, our car runs 285/30/18 A6 Hoosier front on 10.5 inch wheels with rolled fender lip and 2 1/4" coilovers at 2.4 degrees camber with no problem. I am thinking on going to 11" wheels as camber will be 3 degrees with adjustable upper arms next year.
The rear has 315/30/18 A6 Hoosiers on 10.5 inch wheels. Again, with rolled fender lip and 2 1/4" coilover. The rear longitudinal trailing arm is aftermarket, and moved inboard as far as possible. The tires still rub the arm, inner fender well and outer fender lip, just barely under 1.35G loads. It is amazing how much the tire flexes under load, as the static clearance to the trailing arm is about 1/2". Tried to go to an 11" wheel and the stretched tire was just a little to big. If you are running 285's on the rear, you should have no problem on clearance.
