Underinflated or overinflated tires

Underinflated tires
G
WARNING
Tires with pressure that is too low can
overheat and burst as a consequence. In
addition, they also suffer from excessive and/
or irregular wear, which can severely impair
the braking properties and the driving
characteristics. There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
overheat, leading to tire defects
R
adversely affect handling
R
wear excessively and/or unevenly
R
have an adverse effect on fuel consumption
R
Overinflated tires
G
WARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the
driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel.
Overinflated tires may:
increase the braking distance
R
adversely affect handling
R
wear excessively and/or unevenly
R
have an adverse effect on ride comfort
R
be more susceptible to damage

Maximum tire pressures

Example: maximum permissible tire
:
pressure
Never exceed the maximum permissible tire
inflation pressure. Always observe the
recommended tire pressure for your vehicle
when adjusting the tire pressure
( page 387).

Important safety notes
Observe the notes on tire pressure
( page 387).

Checking tire pressures manually
To determine and set the correct tire
pressure, proceed as follows:
Remove the valve cap of the tire that is to

be checked.
Press the tire pressure gauge securely onto
