WARNING
Insufficient tyre tread will reduce tyre
traction.
The
tyre is no longer able to dis-
sipate water. This means that on wet road
surfaces, the risk of aquaplaning increa-
ses, in particular where speed is not adap-
ted to suit the driving conditions. There is
a risk of accident.
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 tyre 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 mini-
mum tyre tread depth is reached.
!
If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage the
wheels or tyres.
Modification work on the brake system and
wheels is not permitted. The use of spacers or
brake dust shields is not permitted. This
invalidates the general operating permit for
the vehicle.
Check the wheels and tyres for damage at least
once a month, as well as after driving off-
road or on poorly surfaced roads.
Run-in new tyres at moderate speeds for the
first 100 km. The tyres only attain their max-
imum performance after this distance.
Vibrations, audible noises and unusual han-
dling characteristics, e.g. pulling to one
side, can indicate damage to wheels or tyres.
If you suspect a tyre defect:
X
Reduce vehicle speed.
X
Stop the vehicle as soon as possible.
X
Check the wheels and tyres for damage.
If you find no signs of damage, have the
wheels and tyres checked at a specialist
workshop.

G
WARNING
Never interchange the front and rear wheels
as they have different dimensions, e.g.
size,
offset
etc. Otherwise, there could be a
negative effect on the road holding and you
could endanger yourself or others.
G
WARNING
Exceeding the stated tyre load-bearing
capacity and the approved maximum speed
could
lead
to tyre damage or the tyre burst-
ing. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe
the tyre load rating and speed rating
required for your vehicle.
G
WARNING
If wheels and tyres of the wrong size are
used, the wheel brakes or suspension com-
ponents
may
be damaged. There is a risk of
an accident.
Always replace wheels and tyres with those
that fulfil the specifications of the orig-
inal part.
When replacing wheels, make sure to fit the
correct:
R
designation
R
type
When replacing tyres, make sure to fit the
correct:
R
designation
R
manufacturer
R
type
!
On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, since this could dam-
age the electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
