I agree with most of the guys 60-65 in front and 40-45 in the rear duals. Note: Having the rears at 45 will allow you to pull what stated earlier in addition it will allow for even tread-wear as well. I know this sounds crazy but I have been using the ride-rite air bags for the last 6 months and when empty the truck actually rides pretty durn good!!! I really believe the air-bags with about 7 to 10 PSI actually removed a lot of the buckiness I had with my dually. Call me crazy and would imagine that most of the guys might not agree with me but I was extremely pleased with the ride of the truck when I installed the air bags. As far as pulling the air-bags are a no-brainer for sure. I currently haul loads between 6k and 18k on a regular basis and the air-bags help big-time with the rear-end squat. Good luck and remember this is my . 02 ;-)
