Is there a standard amount of PSI that folks are running in airbags in regards to weight of the trailer or is it just whatever gets the truck and trailer leveled out? Thanks.

I use enogh to level the truck and trailer.

The max is 100 psi. The most I have ever put is 75.

Most have a min of 5psi...keeps the bag from sagging where it shouldn't.

Most pressure I use is 60-70psi. Levels the truck out and keeps the suspension off the bump stops.

I run about 60 when towing the Willie Wagon. About 7-8 if empty so I con't have to worry about gauge accuracy.

Don't know if this is the proper way, but, I find highth of rear bumper, hook up 5er, and bring back to same highth. On mine it's 40#.

I run right at 10 empty and do the bumper height method like parklane.

With my slide-in camper its beneficial to add enough air to help the suspension but not completely unload the leaf springs (typically 25 - 30 psi for my camper); partial load on the springs helps maintain vehicle stability.

After much tests, I have learned to set mine to 47 psi....Lower is ok, but less side to side sway wih the 47.

Looks like your getting hits from all over the board!
I run 20 to 25 lbs in mine. That keeps the truck level with the el grande 5ver.

I just got done loading my 22ft enclosed with all my worldly posessions. 95 psi barely got her level.

We use an 06 3500 series with the firestone airbag system,
Pulling a 40ft gooseneck flatbed, hauling up to 20k pounds,
keeping the psi at about 30psi seems to work the best for the smoothest ride.

Firestones and pulling a heavy 5th wheel. 27 to 30lbs.

I've got the Firestone airbags on my truck. I run them about 25 PSI empty and 75 to 80 when I'm pulling my RV/toyhauler, a 26 foot Keystone.

Rides great either empty or loaded with these bags. This by far is the best upgrade I've done.

I have Firestone Ride-Rite Air Bags on my truck and unless I am carrying something heavy I keep around 10 PSI in them.

They were all part of an attempt to get a better ride but after I reworked my springs I don’t really use them.

The Firestone convoluted bags have an internal bumper built in so if they were run empty they will not be damaged.

I was told for every 1 PSI of air they would lift 10# of weight.
