Bingo! And, now you know why we check the pressures in the slicks between rounds drag racing. The side sitting in the sun will be higher than the shaded side. Uneven pressure = uneven traction on launch.

drivers side rear--4300 lbs.....passenger front--6700 lb.....passenger rear--4500 lbs..
i didn't have a chance to weigh the rig before so i just put 95 lbs in and hoped for the best.

my nephew work for the county road commission as a foreman and had access to the weigh masters scales... those numbers are what the dials rested at.
could someone PLEASE help me out ?
I would always go with the chassis says for tire pressure or check the the tire sidewall but we have a chart at work and these numbers are for semi trucks but on steer axles with 12,500lbs axle is 110lbs and drive axles are 95lbs and I doubt you have a 13k lb front axle but they are 120lbs, I run 100lbs front and 95 on the rears.
