My car is factory unlowered.

Wow....I wouldn't think that you would lose that much for mpg just from the bump up. Just out of curiosity did you happen to weigh your stock wheel/tire and then also weigh your new wheel/tire to see the difference? I know that the manufacturers post weights, but I trust in person verification myself to be sure. MUSKOKA800 is right too that you might be driving different with better performing tires.
