When you are driving only with driver and co-driver and a little load, the load is moslty front and back the same, so the pressure can be the same front and rear.
So 35 all around would not be bad.
In Europe before 2000, an advice was give for normal use, wich was meath for 3 persons and a little load, and was front higher pressure then rear even.
After 2000 this normal use advice was not given anymore.
But for this you have to calculate and need the empty weight and motor in front or back for estimating the division between front and back.
