Higher tire pressure helps too. I usually set mine at recommended max.

I doubt just tires make that huge difference in mpg. I would look to the winter formulation fuel, coupled with lower ambient operating temperatures as primary factors to lower mpg vs. just the 'tires.' Cold-weather mpg is dreadfully lower across the board.
