Information on noise or unusual driving
ch
aracteristics
While driving, pay attention tovibrations, noises
and unusual driving characteristics, e.g. pulling to
one side. This may indicate damage tothe wheels
or tyres. If you suspect that a tyre is defective,
re duce your speed. Stop theve hicle as soon as
possible tocheck if wheels and tyres ha vebeen
damaged or are no longer functioning properly.
Hidden tyre damage could also be causing the
unusual driving characteristics. If no signs of

WARNING Risk of injury duetodamaged
tyres
Damaged tyres can cause tyre pressure loss. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. Check
the wheels and tyres of your vehicle for
damage regular ly, i.e. at least every two weeks,
as well as af ter driving off-road or on rough
ro ads. Damaged wheels can lead toa loss of tyre
pressure.
Look out forth efo llowing types of damage, for

R cuts in the tyres
R punctures in the tyres
R tears in the tyres
R bulges on tyres
R deformation or se vere cor rosion on wheels &
WARNING Risk of aquaplaning due to
insuf ficient tyre tread
Insu fficient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi‐
cle is not adap tedto suit the conditions. #
Thus, you should regularly check the
tread de pth and the condition of the
tread across the entire width of all
tyres. Minimum tread dep
thfor:
R Summer tyres: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legally-prescribed limit for
th e minimum tread dep thisreached. Conduct
thefo llowing checks regular lyon all
wheels, at least once a month or as requ ired, e.g.
before a long journey or when driving off-ro ad:
R check the tyre pressure (/ page 250)
R check theva lve caps

At temp eratures below 10°C summer tyres lose
elasticity and therefore traction and braking
po we r.Chan gethe tyres on your vehicle toM+S
