Q & A: Air-Bag Specs

Q. We have air bags in the front suspension of our motorhome on a GM
P-chassis. We can’t find inflation specifications. Can you help?


A. As per
Firestone specifications for air bags on P-30 chassis, it calls for a maximum of 60 psi and
a 30 psi minimum in front. If it has rear air bags, use 90 psi maximum/10 psi minimum.
