Ground pressure (driving)
The tire contact surface can be changed by means of tire
pressure.
The high pressure on the tires provides a smaller contact
surface (1) and the low pressure on the tire provides a larger
contact surface (2).
The contact surface with the ground is very important for the
compaction result. The total weight divided by the quantity of
tires provides the correct pressure for the wheel, according to
the following table.
