14 inch wheels are on their way out.
Soon you will only be able to get 14s made in china that will only be "DOT approved" because they carved it into the tire mold.
The only time smaller tires will get you better fuel economy is if you regear the transmission or differential to a numerically lower ratio.
You cant just expect to put smaller cheaper wheels on and get better fuel economy.
