Hi David,
First & foremost it depends on the make of tyre. Factory recommendations should be on the wall itself.
secondly, 50psi would be the limit & for highway driving. I run around 36psi for most off road but agin depends on weight

My Cab Chassis tyre placard reads the same. I run STTs at F32, R34 fully loaded (and I use the 4psi rule). The tyres exhibit a 'slight bulge' of the sidewall and that's where I start my pressures from.

I think that figure only relates to those using the skinny 7:50 tyres or utes David , as 29 / 33 is normal for wagons.

From your post I can't see what sort yours is

I rang the manufacturer of my tyres recently after a tyre service and a wheel alingment company recommended pressures that were way above the factory pressures. I was told to stick to the car manufacturer's pressures and never exceed them by more than 4 psi. They also said, along with a lot of other things, that the air supports the weight and no matter what tyres you have, 1 psi will support 70 kg.

Car manufacturers will give you a pressure for unloaded and fully loaded. Most cars are usually somewhere between those two weights and a few are overloaded so finding the right pressure can be a bit of a guess. I think the best way is to weigh each end of your car when it has its normal load in it and then ring the manufacturer of your tyres and discuss it with them.
