Notes on regularly inspecting wheels and
tyres
Tyres are of particular importance to the operat‐
ing and road safety of the vehicle.
Therefore regularly check the following points:
R
tyre condition
R
tyre tread
R
tyre pressure
Tyre condition
& WARNING Risk of accident from dam‐
aged tyres
Damaged tyres can cause tyre pressure loss.
As a result, you could lose control of your
vehicle.
#
Check the tyres regularly for signs of
damage and replace any damaged tyres
immediately.
Before starting your journey, check the tyre con‐
dition for the following points:
R
external damage
R
foreign objects in the tyre tread
R
foreign objects between the tyres (on vehicles
with twin tyres)
R
cracks or bulges
R
uneven tread wear or excessive wear on one
side
Tyre damage can occur through the following
points, for example:
R
the operating conditions of the vehicle
R
tyre ageing
R
kerbs
R
foreign objects
R
insufficient or excessive tyre pressure
R
weather conditions and environmental factors
R
contact with oil, grease, fuel
Tyre age
Tyres age, even if they are used infrequently or
not at all. Operating and road safety diminish with
the age of the tyres. For this reason have tyres
more than six years old checked and, if neces‐
sary, replaced at a qualified specialist workshop.
This also applies to the spare wheel. Date of man‐
ufacture 1 informs you about the age of a tyre.
The first and second digits refer to the week of
manufacture, starting with "01" for the first calen‐
dar week of the year. The third and fourth digits
refer to the year of manufacture. For example, a
tyre that is marked "3818" was manufactured in
week 38 in 2018.
Tyre tread
&
WARNING Risk of aquaplaning due to
insufficient tyre tread
Insufficient tyre tread will result in reduced
tyre grip. The tyre tread is no longer able to
dissipate water.
This means that in heavy rain or slush the risk
of aquaplaning is increased, in particular
where speed is not adapted to suit the condi‐
tions.
If the tyre pressure is too high or too low,
tyres may exhibit different levels of wear at
different locations on the tyre tread.
#
Thus, you should regularly check the
tread depth and the condition of the
tread across the entire width of all
tyres.
Minimum tread depth for:
R
Summer tyres: 3 mm
R
M+S tyres: 4 mm
#
For safety reasons, replace the tyres
before the legally prescribed limit for
the minimum tread depth is reached.
