Tread wear indicator
The base of the side of the original tyres on
your vehicle show 1.6 mm high tread wear in-
›››
dicators Fig. 250. The position of these in-
dicators is given on the tyre sidewalls by the
letters "TWI", triangular symbols or other
symbols.
The useful life of the tyres depends pri-
marily on the following factors:
Tyre pressure values
Under-inflation or over-inflation will consider-
ably reduce the useful life of the tyres and im-
pair the vehicle's handling. Therefore, check
the tyre pressure, including the spare wheel,
at least once a month and before any long
journey.
Inflation pressures for summer tyres are lis-
ted on a sticker inside the fuel tank flap
›››
Fig. 251. The pressures for winter tyres are
0.2 bar (2.9 psi/20 kPa) above the summer
values.
Always check the pressure when the tyre is
cold. Do not reduce over-pressure in warm
tyres. The tyre pressures must be altered to
suit notable changes in the load being car-
ried.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort ("comfort" tyre pressure). When
Wheels and tyres
driving with comfort tyre pressure fuel con-
sumption may increase slightly.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Wheel balancing
The wheels on new vehicles are balanced.
Various factors encountered when driving
can cause them to become unbalanced,
which results in vibration of the steering
wheel.
The wheel must be rebalanced if a new tyre is
fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect front or rear wheel alignment cau-
ses excessive tyre wear, frequently on one
side, and also impairs vehicle safety. If tyre
wear is very irregular, contact an Official
Service.
Tyre damage
To avoid damage to tyres and wheels, only
drive over kerbs or similar obstacles slowly
and at a right angle if possible.
Check tyres and wheels regularly for dam-
age (punctures, cracks, blisters, deformities,
etc.). Remove any foreign objects embedded
in outside of the treads.
Unusual vibration or the car pulling to one
side may indicate that one of the tyres is
damaged. Reduce speed immediately and
stop if you suspect that a wheel may have
been damaged! Check the tyres for damage
(blisters, cracks, etc.). If no external damage
is visible, drive slowly and carefully to the
nearest Official Service and have the vehicle
inspected.
Low profile tyres
Low profile tyres, compared to other rim and
tyre combinations, offer a broader tread and
a greater rim diameter along with a lower
height of the tyre sidewall. This results in a
more agile driving behaviour. However, on
roads that are in poor condition, this might af-
fect comfort and cause more noise.
Low profile tyres may deteriorate more quick-
ly than standard tyres, for instance due to
strong knocks, potholes, manhole covers and
kerbs. Therefore, maintaining the correct tyre
pressure is particularly important

To avoid damage to tyres and wheels, drive
with special care when driving on roads in
poor condition.
Visually inspect your tyres every 3,000 km re-
garding damage, e.g. flattening/cracks on
the tyre sidewall or deformations/cracks on
the rims.
