indicators is given on the tyre sidewalls by
the letters "TWI", triangular symbols or other
symbols.
The useful life of the tyres depends primarily
on the following factors:
Tyre pressure values
Under-inflation or over-inflation will consider-
ably reduce the useful life of the tyres and
impair 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. 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.
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 damage
(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.

If the wear is visibly greater on the front tyres,
they should be exchanged for the rear tyres

tyres will then last for about the same time.
To ensure that the wear is equal on all tyres
and maintain their optimum useful life, they
should be changed around every 10 000 km.
Storing tyres
When you remove the tyres, mark them in or-
der to maintain the same direction of rotation
when they are installed again.
When removed, the wheels and/or tyres
should be stored in a cool, dry and preferably
dark location. Store tyres in a vertical posi-
tion, if they are not fitted on wheel rims.
