PacBrake bags required 5psi empty. Did not notice and difference. Personally never heard of 10 psi min.
I've always wondered what one condition or 1/2 ton truck the minimum air pressure was written for. My dually has overload springs and I've driven many times with the airbag valve stems removed with no damage to my bags. So, I've always assumed that the minimum air pressure was written for a weak or overloaded condition on specific class of trucks.
I am under the impression that the minimum is for bottoming out, and not damaging the airbag. I have to guess the OE air ride Rams have air in them all the time, and automatically adjust to weight.
My aftermarket Airlift air bags have a bump stop in them ,and supposedly can be run empty. I don't, I run 5 psi when not towing my fifth wheel .
