On our 2012 F350 Dually we keep the pressure as directed on the door and got 64,000 out of the first set of tires with even wear, in 2017 we traded the truck at 107,000 with second set of six good condition tires. Here on the farm we temporarily put in higher pressure when moving very heavy loads. The recommendations on the door are most likely based on best-practices for general use.
