I only run 60lbs of air in all tires on my dually. I also have the trailair pin box and have added the tri glide system. I also took off the overload stoppers on the leaf (top) springs and installed firestone air assist bags. I run 40lbs of pressure in the air assit bags when towing. Which puts the front of the trailer a little higher than the back, truck sits level when hooked up. If your trailer is way off from level you may have to adjust trailer by changing to a different hole in your rear shackle. I am now content with the ride while towing or not. My weight on the pin box is 2840lbs. I also changed shocks on the truck but that did not make any difference.
