ok since it looks like i am going the wrong way with the tire thing, i was looking to lower my drag with the narrower tires, should i look into blocking off air to the front of the car? if so do i block off parts of the bottom of the grill(under the bumper) first or should i look somewhere else? i am kind of looking for a priority list of how to improve mileage quickly. i did all the normal tune up stuff and took up tire pressure from this i saw about 5% pick up, as a test i put some duct tape across the grill(above the bumper). am i on the right track and what obvious stufff did i miss?
