Fig. 323 Tyre wear indicator / wheel change
The tyre wear increases in the following circumstances.
▶
Incorrect tyre pressure.
Driving style (e.g. fast cornering, rapid acceleration / deceleration).
▶
Incorrect balancing of wheels (have the wheels balanced after changing

out when this indicator is flush with the tread. Markings on the walls of the
tyres with the letters "TWI" or other symbols (e.g. ) indicate the position of
the wear indicators.
For uniform wear on all tyres, we recommend that you change the wheels ev-
ery 10,000 km according to the schedule
WARNING

risk of accident.
Improper wheel alignment affects the driving behaviour - there is an acci-

tyre damage. Reduce speed and stop! If no tyre damage is evident, seek the
assistance of a specialist garage.
