So I got this truck. A 2000 Chevy 3/4 ton. The tires currently have 50 psi. The tires say 80 psi max on them. The side of the door says 45 psi fnt and 60 psi rr. I'm assuming that's front and rear. So what should my tires be at with nothing loaded in it? I want the best possible gas mileage but not a terribly bumpy ride if possible.
