So...you're planning to run 9.5" +36? Yes, I'd think you'd need 245 if you don't want to do any fender rolling. Even then, it may rub.
Remember that this is NOT an exact science! Cars differ -- sometimes the subframes are shifted slightly left or right relative to the car, for example -- and tires differ. One 245 width tire will NOT be exactly the same width as another. When we're talking mere millimeters of clearance, be prepared to make adjustments as needed.
The other thing that I keep seeing here is "I don't want to roll my fenders, under any circumstances." Fender rolling is NOT that scary. Done properly, it's a minor modification that is harmless, invisible, and not very expensive.
