13.5 Tyre pressure
The payload and the durability of tyres is directly dependent on the tyre pres-
sure. Air is a volatile medium. It is unavoidable that it will escape from tyres.
As a rule of thumb it can be assumed that a filled tyre loses pressure at a rate
of 0.1 bar every two months. To prevent the tyres becoming damaged or burst,
check the tyre pressure regularly.
X
Tyres overheat if the tyre pressure is too low. This can cause serious
tyre damage.
X
Check tyre pressure before a journey or every 2 weeks. Wrong tyre
pressure causes excessive wear and can lead to damage or even to tyre
burst. You can lose control of the vehicle.
X
Use only valves that are approved for the specified tyre pressure.
Z
Check the tyre pressure on cold tyres. Do not reduce the higher tyre pres-
sure when the tyres are warm.
Z
The information on pressure levels is valid for cold tyres and loaded vehi-
cles.
Z
Pressure in hot tyres must be 0.3 bar higher than in cold tyres. Recheck the
pressure when the tyres are cold.
Z
The valve used must be approved for the air pressure. We recommend the
use of a metal valve for pressures greater than 4.75 bar.
Z
The tyre pressure tolerance is +/- 0.05 bar.
Z
For the maximum permissible axle loads for your vehicle please refer to
specific documentation.
Z
The tyres are part of the base vehicle. Information regarding tyre pressure
can be found in the instruction manual of the base vehicle.
