Run max cold pressure for the best wear. I have read several threads on this where the engineers have turned it into a rocket project by breaking it down to tire pressure vs trailer weight on each axle, blah, blah, but that's what engineers do. Max inflation means less surface contact, less heat, and thus less wear.
