If I remember correctly, putting light weight tires and wheels on a car will increase your 1/4 & 1/8th mile times on the track as well as slightly reducing your stopping distance.
The new 2009 Escape Hybrid Limited has 20.4 pound wheels and 29.4 pound tires. There are 18.1 & 16.4 pound lightweight SUV wheels available from TireRack. Is there any way to figure out how much putting lighter wheels on would benefit fuel economy?
