The door placard recommends 32psi, but I like to keep them a little higher at about 35psi. From what I understand, your mpg will actually improve with higher pressure because less of your tire is making contact with the ground, however that also means that your tire won't wear evenly and the life of the tires will be shorter. A week after I got my Tahoe, before I realized the recommended psi was only 32, I drove it 1,000 miles round trip down to the beach at about 40 psi and was getting 20-21mpg (highway).
More psi keeps the rolling resistance lower....... which means better mpg.
The center will wear out faster though.
