HI Andrew,
I have 295/35 18s on an 11 inch rim on the rear, they are a tight fit as they did rub on the inner guard.

There is also camber of the rear to concider, if you run with a lot of negative camber this will affect things as well.

If you like try one of my rears and see how they fit then you can measure the offset and front face etc.
