Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the wheels on
one axle should not vary by more than
2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap around front wheels
and rear wheels periodically. Ensure
that the direction of rotation of the
wheels is the same as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be
necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle
modifications.
Ensure that the direction of rotation of
the wheels is the same as before and
according to tyre manufacturer
instructions.
After converting to a different tyre
size, have the label with tyre
pressures replaced.

Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add
no more than 10 mm to the tyre tread
and the inboard sides (including chain
lock).
