G'day fellow travellers! :) Does anyone know the recommended tyre pressure I should be having when carrying a load? I have a Toyota Hilux LN106R currently packed with my valued belongings and camping gear and relocating from the east coast to the
Pilbara... so a long journey ahead. The additional weight under the canopy is approx 450kg. My Tyres are a set of Bridgestone Duelers 31x10.50R15LT any tips on the pressure I should be running??? and should this remain the same on unsealed roads??? Thanks! :)

I used to run same tyres in that size on a 60series. Punctured 3 tyres in a day once from running pressures that were too high.
The Bridgestones in that size are a fairly light duty tyre - despite being LT.
They are the same as the old 6-ply tyre. You will find the max pressure written on the sidewall to be around 50psi which is fairly low for a 4wd tyre.
My suggestion is to run say 28psi front and 35psi rear on the bitumen and see how it goes. On gravel, reduce the pressures to say 24 front and 28 rear to reduce the likelihood of tread punctures.
Tyres pressures vary with your load and setup - you need to experiment as you go.

Depends what roads you will be on.
On Canning trip I weighed 4.7 tonne loaded, including camper.
Most outback roads I run approx 26psi, and 22 in the camper, top speed 80 km/hr
In the Canning itself I run 12 front, 15, rear, and 12 camper, and kept mostly under 20 km/hr.
Bitumen roads I run 40 front, 44 rear, and 36 camper, and sit on the speed limit.
All pressures hot.
Hope this helps
Cheers
