Hello!
I am still quite new to the world of aerodynamics, but to me it seems that a 2 inch lift (that's 5 cm!) will affect your MPG noticable. Think of the extra air that can get under the car, where it's a mess without adjustments. A good undertray will probably help you a lot.
But also don't forget the extra air resistance against the tires. The frontal area is enlarged and that's never good for MPG. For this you can make an airdam or deflectors for those wheels.
But but does the car really go up 2 inches because of new tires? 2 inch higher tires will only raise the car 1 inch.
