te rist ics
Make sure there are no vibrations, noises or
unusual handling characteristics when theve hi‐
cle is in motion. This may indicate that the
wheels or tyres are damaged. Hidden tyre dam‐

s onregular lyinspecting wheels and
tyres &
WARNING Risk of inju rydue todamaged
tyres
Damaged tyres can cause tyre pressure loss. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. &
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. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, for
ex ample, prior toa long journey or driving off-
ro ad:
R Check the tyre pressure (/ page 384).
R Visually inspect wheels and tyres for dam‐
age.
R Check theva lve caps.
R Visual check of the tyre tread dep thand the
tyre contact su rface across the entire width.
The minimum tread dep thfor summer tyres
is 3 mm and for winter tyres 4 mm. Note
