When I picked up my new Titan, the tire pressure for the BF Goodrich tires was set for each at 44 psi. That's 9 psi over recommendations. I've let it down to 42 psi. The ride is excellent! The dealer told me the factory loads the tires up since they rachet the trucks down onto the transport truck, and the higher pressure helps prevent flat spots on the tires. Anyway, sounds logical.

The only "upside" I can think of to running with lower pressure is ride quality. The ride will be softer. Otherwise, MPG decreases and tire wear increases.
