I know tires have different roll resistance but the mileage would be negligible.

Actually it can happen. When you increase your rotational mass the engine has to work harder to spin the wheel and tire. As well as your brakes work harder to stop it from spinning. A lot more goes into a wheel/tire set-up than looks.
