6 axle Reitnouer trailer w two drop steer axles

im driving a 6 axle Reitnouer trailer w two drop steer axles, it keeps pushing me while going around corners and round abouts almost jackknifing. I'm good with weight I don't think I'm setting the air pressurers properly on the drop axles the trailer is a rear quad and the drop axles are in the middle. the wet weather is coming little worried of the coming months

any help for this

 

on the gauge i have it set at 68 psi on both i believe that would be around 17000 lb
loads range around 82000 lb usually load 48000 from landing gear back 17 feet 34000 to the rear

i was told from owner to load heavy on front and lighter on back, am i loading wrong maybe

i will try doing what you said unless you see im doing something more wrong

thanks for the reply and help
