The air bags can be inflated to as little as 5 psi running pressure for very little ride quality impact with light to no cargo loads.
Every 10 psi increase in the air bag pressure will add appx. 500 lbs. load carrying capacity, up to the maximum inflation pressure of 100 psi and a factory rated capacity of 5,000 lbs.
Firestone air bags can be inflated with a shop air compressor or even most portable 12 volt or cordless style air pumps.
