Once you have the weights, you can adjust the air assist bag pressure according to your manual.
Four corner weights are not necessary for the pressures in the P32 air assisted front suspension, only the total weight on the front axle as loaded for travel.
The minimun is 55psi. I suggest starting at 70 psi and adjust from there until the ride and handling are the best.
Pressure changes of as little 2-3 psi can make quite a difference. Keep the pressure the equal in both bags.
