Wheels And Tyres - Lancia Lybra Owner's Handbook Manual

WHEELS
AND TYRES
TYRE PRESSURE
Check the pressure of each tyre, in-
cluding the spare, every two weeks or
so (every month anyway) and before
long journeys.
The pressure must be checked when
the tyre is rested and cold.
It is normal for the pressure to rise
when you are driving. If you have to
check or restore the pressure when the
tyres are warm, remember that the
pressure value must be 0.3 bar above
the specified value.
Tyre pressure must be
correct to ensure good
road holding.
Wrong pressure causes uneven wear
of the tyres (fig. 20):
A - Correct pressure: tyre wears
evenly
B - Under inflated tyre: shoulder
tread wear
C – Over-inflated tyre: centre tread
wear.
If the pressure is too low
the tyre overheats and this
can cause it serious dam-
age.
Tyres must be replaced when the
tread wears down to 1.6 mm. In any
case, comply with the laws in the
country where the car is being driven.

IMPORTANT
As far as possible avoid sharp brak-
ing and screech starts.
Be careful not to hit the kerb, pot-
holes or other obstacles hard. Driving
for long stretches over bumpy roads
can damage the tyres.
Periodically check that the tyres
have no cuts in the sidewalls, abnor-
mal swelling or irregular tyre wear. If
any of these occur, have the car seen
to at a Lancia Dealership.
Avoid overloading your car: this can
seriously damage wheels and tyres.
If you get a flat tyre, stop immedi-
ately and change it so as not to dam-
age the tyre, the wheel, the suspension
and the steering.
Tyres age even if they are not used
very much. Cracking of the tread rub-
ber and the sidewalls are a sign of this
ageing.
