Tread dept h
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
deepe r tread are on the front ax le.
For information on how to change a wheel
- see page 174.
Che ck the tyre pressures - see p age 215.

For safety reasons, tyres should be
replaced when their tread depth has worn
down to 2 to 3 mm. The legal permissible
minimum tread depth (1.6 mm) has been
reached when the tread has worn down as
far as one of the wear indicators.
A number of wear indicators are sp aced at
equal intervals around the tyre, within the
tread. Their position is indicated by
markings on the tyre sidewall.
General inform ation
Note that the danger of aquaplaning is
greater if the tyres are worn and if the tyre
pressures are not correct.
Tyres age, ev en if they are used only ve ry
little or not at all. A spare wheel which has
not been used for six years should be used
with care.
Never fit used tyres the previous history
and use of which you do not know.
