Think about it this way. MPG is about:

1) Weight
2) Efficiency of drive train
3) Aerodynamics

So if you drop the weight by 10% and the other two factors stay the same, then you will gain something in MPG. Take out the tire, and the rear seat and see what the improvement is, then calculate what the projected savings are.

All about the math.
