1-up pressures for 2017 standard model are F/R 2.0/2.5 bar 29/36 psi.
Pressure is tyre and use dependant.
TKC80 are soft. I’ll not go below 25psi front & rear - bent the front rim 3x on rocks.
Mitas E07 are much stiffer tyre. I’ll go as low as 22psi f/r. Lower on rear (15psi) if I desperately need traction but I’ll air up when I hit firmer ground.
80+ kmh on hard pack forest service roads only needs one nasty embedded rock or deep pothole to bend a rim or cause a pinch flat if pressures are too low.
For me 25/25psi works pretty well with Mitas E07, E07+ and E10 Dakar. If pounding pavement I run 2/2.5 bar 29/36psi F/R.
