Kind of a wild guess, but I would expect something around the 5 mpg range. If it were much more or less out of that range I'd be surprised. Aerodynamically you're increasing frontal area and the larger tires increases weight. You'd also be degrading sprung to unsprung weight so it'll ride a little harder all other things being equal.
