Anybody have any experience with quad axle trailers. How can you tell how much pressure to run for optimal weight distribution. I can scale 120,000 with 12 on steers 34 on drives and 18.5 on each trailer axle. I know if I am showing about 50 lbs on my suspension gauge I am about right on my drive weight but I have no clue on how to adjust the drops I asked someone else and he said he ran like 50 lbs on the front and 55 on the second well that didn't work because my drives were really light so I run 45 and 50 but I have no clue what the weights are. I have nowhere to axle weigh around here so I was just trying to see if anyone had a formula.
