My winter steelies are lighter than the stock alloy wheels.

Oh, right, you asked a question, too. Like others said, it depends how much weight you lost. This is a total off-the-cuff estimate, but you will probably lose the same amount of weight by burning half the fuel in your tank.

Want better mileage, don't fill all the way.
