I dropped from 13" steel to 13" magnesium alloy ('85 CR-X Si wheels, specifically) which I'm pretty sure weigh less than 10 lbs each. (sans tires)

The end result was negligible increase in gas mileage (2 mpg) and significant increase in both acceleration and deceleration, including a much touchier response to the accelerator... it made me aware of exactly how much power I was wasting to propel those 14 lb steel wheels, vs. the sub-10 lb mags.

If that helps.
