Hi - I've been on the Metzeler site to check the correct tyre pressures for my bike & the tyres that I have (newly) fitted. I have a Siebenrock 860 kit fitted so that adds a small amount of weight.
.
The recommended pressures front and rear are 32psi for both tyres. An extra 2 psi for a passenger.
.
I have panniers and a back rest so I'm thinking that 34psi should be the normal for the rear tyre solo and 36 psi with the boxes and passenger.
.
Advice form the fonts of all knowledge most welcome
