depending on what it says in de side on the tire

e.g. my off road Racing Ralph from Schwalbe say: inflate between 2,0 and 4,0
atm.
depending on the status of the tracks I will be riding I make a choice:

dunes or beach: 1,8 - 2,0 (front - rear)
loose sand in fores: 3,0 - 3,5
hard rock: 3,0 - 3,5

the race bikes Schwalbe Stelvio's can take air pressures up to 10 atm.
I inflate them with 7.0 - 8.0 on cobble stones and increase to 8.0 - 9.0 for
time trial like events.

How does rider weight factor into tire inflation?

Heavier riders can get better performance and avoid pinch flats by
exceeding the printed maximum inflation. Very light riders can get
better handling by slightly under inflating tires.

Did you ever notice that tire inflation pressures are often provided
as a range, not a single pressure?

I'm a bigger rider (235 lbs.), and have found that my Michelins ride
the best for me at about 125 psi. The sidewall maximum is 115 psi.
I've ridden with very light women who have found that maximum
inflation can cause their tires to feel skitterish during hard
cornering.
