Recommended cold PSI is 60 front & 65 rear. They are Michelin 275/65/20 load range E on a 2017 F250 Power Stroke. Should I increase the pressure when towing my 39' toy hauler (Triton by Voltage)?
That rear tire pressure sounds like an unweighted number. Check your sticker again. My chevy sticker says 80lbs in the rear tire (265/75/16s) when loaded. Michelin web site says to go with the vehicle sticker.
