I've heard you get better fuel economy with the tires inflated more. I was reading somewhere to go to the max of the tire for max fuel economy. There is a "correct" tire pressure which will maximise the life of the rubber, if you overinflate you will wear the middle of the tread prematurely, and if you underinflate you will wear the edges (thanks Auto-X-Fil). Depends on tyre, car, driving style and whatever so you need to experiment.
