Says to me have same pressure front and back....I might try a few psi less.
My placard (MY16 110) says 30 front and 48 to 65 rear depending on load.
When it was unmolested I thought these pressures were a little low in the front and a little high in the rear. I ran 32-33 front and 46 rear.
Now with bar and winch up front and constant load in the rear of fully packed drawers I run 34 front and 48 rear. On a trip I tend to bump the front up to 36 and the rear up to 50-54 depending on load. I usually set the front to what I want then set the rears so they are bagging about the same. I’ll drop them about 6psi when I hit the dirt, otherwise I start losing fillings.
Cheers,
Jon
light truck tyres. Usually running 28-30 front with 34 back around town. pacific highway trip plus 6 psi. fully loaded book figures. logging roads etc at less than 60km/hr drop back to around town pressures except when fully loaded.

Placard pressure would relate to the Original Equipment tyre. Change brand/construction/type of tyre/fitted extras,, the placard then becomes virtually meaningless.
Didn’t the puma had different options for type of Tyre?.....does that mean the placards on puma would be differ depending on the type of Tyre fitted?Quote:

At least the OP is thinking about his tyres! Lots of people don't!
My Puma came from factory with 50psi in the rear and spare, the front was lower - maybe 36ish.
Their were at least two choices for tyres. Also, if you optioned HD wheels you got HD springs so more variable....
Of all my Land Rovers. Even when fully laden. I have never run a tyre above 42psi..
Ever....
And I’ve never had a puncture in any of them offroad.
Only puncture was a steel spike debris on the D4 LHR on a highway at 110km/h.
In 30 odd years I’ve had a collective total of 2 punctures - both LHR and both a foreign object on a sealed road.
All my tyres wear evenly and the ride is balanced.
I am with Tombie, I have Never exceeded 40psi in a 4WD tyre and also haven't had that much tyre dramas.
I have always replaced my tyres BEFORE they get too old/worn and I have always checked the tyre pressures regularly and I think this is the main reason why I haven't had too many problems.
As for the tyre placard, Well that goes out of the window as soon as you change the type/size from the original factory fitted tyre/rim.
I notice the Haynes manual for Defenders up to 2016, which arrived yesterday, says 28 front and 36 rear, which seems low to me.
