Probably, but not as much as just a heavy foot. I did some research a while back, and came to the conclusion that every extra 1" in wheel diameter reduces combined mpg by about 1mpg. The f/r 403M wheels and tires weigh an extra 5/6 combined pounds each vs the 400M versions. I opted for the 400M on my AH3 M-sport. You can click in my sig for examples of my mpg.
