Views differ on the optimum tyre pressure for different surfaces; it also depends on various factors such as the type of vehicle, the kind of tyres on it and the load it’s carrying. That said, a rule of thumb for the average 4WD is 2–2.2 bar for tarred roads, 1.8 bar for gravel roads and 1 bar (15psi) for sand. For sand, it’s really important to deflate the tyres to increase the surface area, so that this can improve the vehicle’s traction. Ask your rental agency what they recommend.
