The number one way to improve mpg is usually driving style . I have a ehybrid and I get 45 in city and usually 35 mpg on highway .

When I got my car new, the dealer had my tires set at 44 PSI all around. The ride is hard as a rock, and the gas mileage has sucked even with pressure up pretty high. I'm hoping another couple thousand miles or after the first oil change that things get better.

Just adjust the tire pressure. Takes only a few moments to do.

It's shipped from the factory at higher pressure, the dealer's supposed to lower it. What's it at now?

As @Frig suggested, your dealer screwed up the pre-delivery prep. 44 PSI is used to reduce bounce and sway when tied down on the transport truck (truck drivers just hate it when their load does the bounce and sway thing ). 36 PSI is the factory recommendation. 2 PSI over probably doesn't hurt.

The previous suggestion that you use the higher sidewall "max" figure is wrong, and dangerous. That number is the maximum pressure that the tire can safely withstand while being driven, and NOT the normal use pressure.
