When driving the truck with the reduced tire pressure, follow the readings of
the tire pressure gauge.
It is prohibited to drive the truck with the reduced tire pressure for the purpose
to obtain smooth running. If the truck travels for a long time, the tire pressure may
rise due to their heating. Do not reduce the pressure in the heated tires so as to
reduce rolling resistance and save the fuel.
