Thread: Tyre Pressures

It would vary by vehicle type as it is determined by the weight of the vehicle. That is why they put it on the guards.

Ummmmm speaking professionally...

you probably want to run with the opinions of people here and not what the ADF runs in their tyres.

of course, if what your asking is "what tyre pressure would the maintainers like the operaters to read from the EMEI's and actually keep in the black round things" thats a completely different answer to what actually happens...

what is actually run in the tyre is generally only ever the nominated pressure for a brief while.. heres how it goes.

tyre is over inflated because its just going to leak down anyway
tyre leaks down to the correct pressure and is checked its right so it'll never be checked again until the handling goes squdgy
the handling goes squdgy so a repair request is raised with a suspected steering/suspenion fault it comes in nearly driving on the rims, the tyres are inflated to the correct pressure and sent on its way and I get to pull a Scotty.

Mick our FFR Perentie is marked 325 kpa on the front and 450 kpa on the rear. I thought these were a bit on the high side and would make the ride rough, so I played around with lower pressures. At these lower pressures I found that the vehicle at times could be a bit daunting if it dropped off the edge of the bitumen on a narrow road etc. The vehicle is never heavily loaded, just two dogs, the wife's golf clubs and our travel bags. I decided that maybe the Army knew what they were about when they came up with those tire pressures, safety, handling, load capacity would have all been given consideration.
I went back to the recommended pressures and found it is so much better to drive, probably feels a bit harsh for the first few kays until the tires warm/soften up a bit.
A while back I picked up a four cylinder engine and had it sitting right at the back of the tub. It was a 500 kay journey and you wouldn't even have known it was there.
Running the recommended (Army) pressure in the front also compliments the "Armstrong" steering.


Cheers, Mick.
