Rear Tyres Pressure and Air suspensions

[Domster]

Hi

second question of the day.
I have a Toyota Hilux invincible (3.0L - 2007) with BF Goodrich All Terrain T/A 31/10.50R15.
I have only had the camper (Northstar) on the truck one time and I notice the back tyres looking very squished as well as the rear of the truck going down.

To what pressure should I inflate the back tyres?
Do I need air suspensions and what make and model would you suggest for my model of truck?

Thank you in advance

Dom

Air suspension need comprise of a couple of air bags on rear axle mounted their model specific brackets, a compressor and air gauge together with control buttons (up and down)

should look a bit like this;


Bags can be DIY but probably easier to get local garage as the bump-stops on axle need unbolting to make room
running the push-fit 6mm air line is easy and siting compressor and running power to it etc is mildly technical

couple of suppliers spring to mind

Both suppliers require your Reg number for correct kit

Amongst help section here is this

On tyre pressure, I have same Hilux with about same tyres and found 47PSI all around works.
fitting air bags on back axle will correct ride height at back with camper on, though you'll need to keep bags minimally inflated [5PSI] when running without camper as they can suffer damage left entirely empty.
