Tyre care and wear
The tyres should be checked frequently for
damage or wear. The greater the depth of tread,
the greater the water clearing properties of the
tyre, resulting in increased levels of grip.
In many markets the maximum wear levels are
subject to legal requirements. Where no such
local regulations exist, it is recommended that
tyre tread depth should never be allowed to fall
below 1.6 mm.
The tyres incorporate raised bars across the
bottom of the treads to indicate tyre wear (A),
the positions of which are marked 'TWI' round
the shoulder of the tyre at regular intervals.
These bars become flush with the tyre surface
when there is approximately 1.6 mm of tread
remaining and the tyres are at their wear limit.
Excessive local damage may result from striking
a kerb, hitting an obstruction or deep pot hole,
each of which can seriously affect the tyre
casing. Such damage will normally be visible
following careful examination of the tyre tread
and wheels.
Incorrect wheel alignment resulting from kerbing
or hitting an obstruction etc. may result in an
uneven wear pattern across the tread pattern
and around the whole tyre circumference.
Where this is suspected, the wheel alignment
should be checked by your Dealer.
Flints, sharp stones and other sharp objects
should be carefully removed from the tyre tread
using a penknife or similar tool. If neglected,
they may work through the tyre.
Any oil or grease which gets on to the tyres
should be cleaned off using petrol sparingly
(take care when disposing of the cloth used as it
will be highly inflammable). Do not use paraffin
(kerosene) which has a detrimental effect on
rubber.
WINDSCREEN WIPERS AND WASHERS
Wiper blades
Windscreen wiper blades should be replaced at
regular intervals or if they become damaged by
the action of road dirt and salt. Never use the
wipers to clear frozen snow or ice from the
windscreen as this will damage the lips of the
blade and adversely affect the wiping
performance.
To replace the blade, pull the wiper away from
the windscreen, press the spring (B) inwards
and push the wiper blade hook (C) from the
arm. Withdraw the blade and fit a new blade
following the reverse procedure.
