Terra Grappler PSI

Had a set of 295/70/18 Terra Grapplers installed on my 2011 4x4 Crew Cab last week. What would be the ideal psi to run in them to obtain the longest treadwear possible. I also pull a 6k pound trailer 5 days a week. Any input would be greatly appreciated.

I run my rears at 65 when towing, and fronts at 42. Seems to wear pretty good, about 20k on my terra grapplers so far and all even

I have the exact same tires as you. From what I read, 65psi all around until you are towing/hauling real heavy. Then 80psi in the rear and 70 front.

That trailer has a 400-1000 tongue weight? Should be fine for 65psi.
