Well. since the newer tires are 2" larger in diameter, and a 1" difference in radius (obviously) Calculate in the flex of the sidewall with 40 psi.. The car maybe only about 3/4 inch taller. If there is any extra drag from the larger frontal area, I think the total circumference benefits will outweigh them.
But , good thinking about this. Its one of the overlooked variables.
Specially in the offroading scene. LOL
