Notes on noise or unusual handling charac‐
teristics
Make sure there are no vibrations, noises or
unusual handling characteristics when the vehi‐
cle is in motion. This may indicate that the
wheels or tyres are damaged. Hidden tyre dam‐
age could also be causing the unusual handling
characteristics.
If you suspect that a tyre is defective, reduce
your speed immediately and have the tyres and
wheels checked at a qualified specialist work‐
shop.
Notes on regularly inspecting wheels and
tyres
&
WARNING Risk of injury due to damaged
tyres
Damaged tyres can cause tyre pressure loss.
#
Check the tyres regularly for signs of
damage and replace any damaged tyres
immediately.
&
WARNING Risk of aquaplaning due to
insufficient tyre tread
Insufficient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
roads, especially when the speed of the vehi‐
cle is not adapted to suit the conditions.
#
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.
Carry out the following checks on all wheels reg‐
ularly, at least once a month or as required, for
example, prior to a long journey or driving off-
road:
R
Check the tyre pressure (
/
page 356).
R
Visually inspect wheels and tyres for dam‐
age.
R
Check the valve caps.
R
Visual check of the tyre tread depth and the
tyre contact surface across the entire width.
The minimum tread depth for summer tyres
is 3 mm and for winter tyres 4 mm.
Notes on snow chains
&
WARNING Risk of accident due to incor‐
rect snow chain fitting
If you have fitted snow chains to the front
wheels, the snow chains may drag against
the vehicle body or chassis components.
This could cause damage to the vehicle or
the tyres.
