Tyre pressure advice please help

[TedDuf]

Hi everyone, we are proud owners of our first motorhome - a Peugeot Boxer 330 Autocruise Starblazer 2004 gross weight 3850kg.
Been trying to google what the correct tyre pressure should be and having a nightmare?
The tyres are all Michelin 215/70R15 CP 109Q.
I will try and attach photos of the plate inside the door, which I understand means 79psi all round ?
I have checked the current pressure and the front are saying 52 psi and the rear 72 psi!
Any thoughts would be gratefully received

I don’t trust garage compressors, I always over inflate them then check them later when they’ve cooled down with my own gauge.

ha, just had an email off a company I do trust for supplying relatively good quality garage type equipment and spotted they had a sale on so although more expensive than my previous link, I’d put more trust in this one...

depends on what you want to spend I guess.
I know halfords do an RAC inflator thing for about £20 quid not sure if it goes up to 80psi without checking though.

how do you know your gauge is the accurate one

I know some of the gauges I trusted in the off road world (ARB) to name one and a bluepoint (Snap-On’s budget range) I thought were good til I bought a “proper’ inflator that came with a specific test calibration certificate... I don’t trust anything else now.
