Tyre pressure

Notes on tyre pressure
& WARNING Risk of accident due to insuf‐
ficient or excessive tyre pressure
Underinflated or overinflated tyres pose the
following risks:
The tyres may burst, especially as the
R
load and vehicle speed increase.
The tyres may wear excessively and/or
R
unevenly, which may greatly impair tyre
traction.
The driving characteristics, as well as
R
steering and braking, may be greatly
impaired.
Comply with the recommended tyre
#
pressure and check the tyre pressure of
all tyres including the spare wheel regu‐
larly:
at least once a month
R
when the load changes
R
before embarking on a longer journey
R
if operating conditions change, e.g. off-
R
road driving
Adjust the tyre pressure as necessary.
#
Driving with tyre pressure that is too high or too
low can:
Shorten the service life of the tyres.
R
Cause increased tyre damage.
R
Adversely affect driving characteristics and
R
thus driving safety, e.g. due to aquaplaning.
& WARNING Risk of accident from repea‐
ted tyre pressure drop
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged.
Insufficient tyre pressure can cause the tyres
to burst.
Inspect the tyre for signs of foreign
#
objects.
