Debunking 7 fuel-economy myths - Yahoo! Autos
This is from Consumer Reports. The last point caught my eyes since i am a tire freak lately. So, i will likely get Conti EcoPlus next time around. But the other points are worth reading, like driving with windows open (thus, those window deflectors sure make sense now!) and no-name gas (esp. since i often use Chevron Fuel System cleaner every 5-10k miles anyways).

Tires with low rolling resistance are always a smart choice
A lot of attention is paid to a tire’s rolling resistance, which is how much energy it takes to roll along. The lower the rolling resistance, the better your fuel economy will be. Maintaining the proper tire pressure will optimize the rolling resistance and real-world performance. Some tires gain low rolling resistance at the expense of wet-braking performance and tread life—a poor trade-off.
It’s better to look first for a tire that provides good all-around performance in important safety areas such as braking, handling, and hydroplaning resistance. Then use rolling resistance as the tiebreaker.
In our testing, we’ve found two all-season passenger-car tires that deliver very good performance and low rolling resistance: the Continental ProContact EcoPlus+ and the Michelin Energy Saver A/S."
