The wrong tyre pressure will have a negative effect on the vehicle's response and lead to high
levels of wear or even a burst tyre → . The correct tyre pressure is particularly important at
high speeds.
Comfort tyre pressure
Depending on the vehicle, the tyre pressure sticker may show details of a comfort tyre pressure
→ Fig. 1 3 . The comfort tyre pressure allows increased driving comfort. Energy consumption
may increase when driving with comfort tyre pressure.
Checking the tyre pressure
—Check the tyre pressure at least once a month.
—Always check the tyre pressure when the tyres are cold. The specified tyre pressure applies to
cold tyres. Tyre pressure is always higher in warm tyres than it is in cold tyres. For this reason,
never reduce the pressure in warm tyres to adjust the tyre pressure.
—Always adjust the tyre pressure to the load level → Fig. 1 4
.
—After adjusting the tyre pressures, always screw the caps onto the valves and observe the
information on the tyre monitoring system.
—Always use the tyre pressure specified on the sticker. Never exceed the maximum tyre
pressure which is given on the sidewall of the tyre
WARNING
Incorrect tyre pressure may cause the tyre to suddenly lose pressure or burst while the vehicle
is in motion. This can cause serious accidents and fatal injuries.
●
If the tyre pressure is too low, it is possible that the tyre temperature will increase to such
an extent when driving that the tread peels off and the tyre bursts.
●
Excessive speeds and overloading of the vehicle can cause overheating, sudden tyre damage
including tyre bursts and detachment of the tread surface, and thus to a loss of control of
the vehicle.
●
If the tyre pressure is too low, the tyres will wear prematurely and the car will not handle
well.
●
●
●
Check tyre pressures regularly, at least once a month, and before every long journey.
All tyres must have the correct tyre pressure to suit the vehicle load.
Never reduce excess pressure when the tyres are warm.
NOTICE
●
●
When attaching the tyre pressure gauge, ensure that you do not position it at an angle to
the valve stem. This can damage the tyre valve.
Always make sure the valve caps are completely screwed on while driving.
Under-inflated tyres can contribute to an increase in energy consumption.
