I just put 4 new Michelin LTS M/S 265/75-R16 E tires on this morning. I used to run 55 psi in front and 45 psi in the rear to get even wear across the tire. I have started there, but it looks like that might be high for unloaded, especially in the rear. What's everyone else running? I want to get a long life out of these things.
