Helpful Expert Reply:

The 21-9015 number that you mention is actually the order number for the "equipped with Ride Rite Helper Springs" sticker and is not the part number for the air bags. But to answer your question the minimum pressure you need to keep in the bags is 5 psi so that they don't fail prematurely but the amount of pressure you'll need to run will be based on what it will take to keep the vehicle level which will be based on how much cargo is loaded etc.
