I have 325/65 18 tires and am looking for some input on tire pressure; what do you run or would you recommend running front/rear/loaded/unloaded? Looking for longevity, mpg sweet spot, but dont want to have to wear a kidney belt. I know I am asking for the world. Your feedback is appreciated.

 

I run 47 p.s.i. front, 45 p.s.i. rear in my 325/70-17s.
