I finally had polyair bags & new rear coil springs fitted to the Pajero today. What a difference they have made. I feel like I'm sitting higher & my tow-ball no longer scrapes on the road when entering or exiting my driveway. It looks visibly higher as well. They should make a huge difference when towing the CT & I'll no longer piss off oncoming traffic at night or scare the possums out of the trees.
The bloke that fitted them only inflated them to 6psi. What do others suggest I run them at under load & not loaded? I realize this depends on the vehicle weight & tow weight but just a general idea.

6psi unloaded is fine..
loaded......try 15 and see how they feel..

I have little ones in my Adventra for towing the KK. I run 6psi unloaded. All you want is some are in them so the springs don't pinch them and cause issues. Mine can take a whopping 40psi and I run this when the KK is fully loaded.
Just remember to pump them up prior to hooking up your CT. I would start with 20psi and then let some out when you hook up if they are too firm. You can pump them up loaded however they tent to baloon out between the springs more because of the load pushing down on them.

I run under 10psi when unloaded and 25 when I've got everything hooked up, engel and dogs in the car too.
As suggested, start with 20psi and see how they feel. Don't run them so that they raise your car higher than it would be unloaded without them there, but just to minimize the sag.

And the time when you do hook up and remember that you haven't inflated them yet, don't stress, just use the jockey wheel to take the load off the hitch whilst you pump them up.

Yep happens more often than you think!

Thanks for the replies everyone. It's good to have an idea of how much air to use & I did not know about inflating them before loading up. Makes good sense. We're heading up to Inskip Point this weekend & with the back loaded, a couple of kayaks on top & the camper in tow, I will definitely start out at 20psi & go from there. Mine have a max pressure of 30psi.
