Notes on tire pressure
& WARNING Risk of accident due to insuf‐
ficient or excessive tire pressure
Tires with either too low or too high a pres‐
sure present the following hazards:
the tires could burst
R
the tires could wear excessively and/or
R
unevenly
the driving characteristics as well as
R
steering and braking characteristics may
be severely impaired
Observe the recommended tire pres‐
#
sures and check the tire pressure of all
tires including the spare wheel:
monthly
R
if altering the load on the vehicle
R
prior to long journeys
R
if the operating conditions change, for
R
example when driving off-road
Adjust the tire pressure where neces‐
#
sary.
Tire pressure which is too high or too low can:
Shorten the service life of the tires.
R
Cause increased tire damage.
R
Adversely affect driving characteristics and
R
thus driving safety, e.g. due to hydroplaning.
& WARNING Risk of accident due to too
low a tire pressure
Tires with pressure that is too low can over‐
heat and burst as a consequence.
In addition, they also suffer from irregular
wear, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics.
Avoid excessively low tire pressure.
#
Tire pressure which is too low can cause:
Tire faults as a result of overheating
R
Impaired handling characteristics
R
Irregular wear
R
Increased fuel consumption
R
& WARNING Risk of accident due to too
high a tire pressure
Tires with excessively high pressure can
burst.
In addition, they also suffer from irregular
wear, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics.
Avoid excessively high tire pressures.
