Tyre condition, wheel condition
Driving over sharp edges can lea d to
hidden tyre damage and wheel da mage
which is only noticed later on; danger of
tyre blow-out.
Drive over edges slowly and at a rig ht
angle if possible. When parking, ensure
that the tyres are not pressed against the
edge of the kerb.
Check tyres regularly for damage (foreign
bodies, punctures, cuts, cra cks, bulges in
sidewalls). Check wheels for damage. In
the event of damage or abnormal wear,
consult a workshop.

Tr ead depth
Check tread depth regularly. Should the
front tyres show greater wear than the rear
tyres, have both front wheels exchanged
with the rear wheels so that the tyres with
deeper tread are on the front axle.
For information on how to change a wheel,
see p age 167.
Check the tyre pressures - see page 207.

For safety reasons, tyres should be
re placed when their tread depth has worn
down to 2 to 3 mm . The legal p ermissible
minimum tread d epth (1.6 mm) has been
reached when the tread has worn down as
far as one of the wear indicators.
A num ber of wear indicators are spaced at
equal intervals around the tyre within the
tread. Their position is indica ted by
markings on the tyre sidewall.
