Wear indicators
There is a 1.6-mm-high wear indicator
the tyres. In some countries, different tyre wear rates may apply.
Markings on the walls of the tyres through the letters "TWI", triangular sym-
bols or other symbols identify the position of the wear indicators.
Replacing the wheels
For uniform wear on all tyres, we recommend that you replace the wheels ev-
ery 10,000 km as shown in the diagram
proximately the same life for all the tyres.
After changing the wheel, the tyre pressure must be adjusted.
In vehicles with tyre pressure monitoring, tyre pressure values must be
saved » page 167.
WARNING
You must have your tyres replaced with new ones at the latest when the
■
wear indicators have been worn down.
Worn tyres do not provide the necessary adhesion to the road surface
■
particularly at high speeds on wet roads. One could experience "aquaplan-
ing" (uncontrolled movements of the vehicle – "swimming" on a wet road
surface).

Tyre damage

Read and observe on page 204 first.
We recommend checking your tyres and wheel rims for damage (punctures,
cuts, splits and bulges, etc.) on a regular basis. Remove foreign bodies (e.g.
small stones) from the tyre profile immediately.
Drive over kerbs and other such obstacles slowly and perpendicularly wher-
ever possible in order to avoid damage to tyres and wheel trims.
Immediately replace damaged wheel rims or tyres.
WARNING
Never drive with damaged tyres – risk of accident.
CAUTION
The tyres must be protected from contact with substances such as oil, grease
and fuel, which could damage them. If the tyres come into contact with these
substances, then we recommend having them checked out in a specialist ga-
rage.
Unidirectional tyres

Read and observe on page 204 first.
The direction of rotation of the tyres is marked by arrows on the wall of the
tyre.
The indicated direction of rotation must be adhered to in order to obtain the
best benefits from the characteristics of these tyres.
These characteristics are mainly.
›
Increased driving stability.
›
Reduced risk of aquaplaning.
›
Reduced tyre noise and reduced tyre wear.
