I was told that you should keep your tires on the trailer at max level, meaning 110 psi cold, for our 3670RL. My question is pertaining to the pressure on the truck tires, on an F350, and the tires say 80 psi max, cold. Going on our first decent haul in two days, six hour ride. Right now the rear tires on the truck are at 80, and the fronts are around 56. Seemed to ride fine on the last short trip, but I'm wondering what others think, although I know it's a topic for what can be too much discussion.
