Like Rusty said, experimentation for your particlular truck and 5er is the only way to determine the best air pressure for ride, stability, and towing attitude. Begin at 60psi and adjust after a short pull up 5psi if the truck wallows,and rear bumper is low. If the ride is too solid adjust down. Keep at it until you are satisfied. I assume you will carry a 12VDC compressor.
