You might improve gas mileage if you step up your tire size. The trade off is loss of horsepower/torque to the wheels as it is the equivalent of switching to a lower differential gear ratio. Another option is to improve your intake system to make it more freeflowing and increase your throttle body size. 360airintakez.com offers some kits that they claim will improve economy if you don't change your driving style with the mod. This offers a good breakdown of tire size to gear ratio guide: http://rough.roughcountry.com/Gear%20Ratio%20Guide.htm
And this is for your tiresize to body lift guide:
