I have just put on a new set of Michelin Defender LTX M/S in 225/75/16 on my 5/7 lowered dually. does anyone have a suggested cold air pressure in the front tires and rears. Thanks . i have 55 lbs cold in them now.

The door jam has a suggested psi rating for any car or truck. I usually run a little higher though when loaded down.
