WHEELS AND
TYRES
38)
Check the pressure of each tyre,
including the space-saver wheel,
approximately every two weeks and
before long journeys: the pressure
should be checked with the tyre rested
and cold.
It is normal for the pressure to increase
when the car is used; for the correct
tyre inflation pressure, see "Wheels" in
the "Technical specifications" chapter.
Incorrect pressure causes abnormal
tyre wear fig. 119:
A normal pressure: tread evenly worn.
B low pressure: tread particularly worn
at the edges.
C high pressure: tread particularly worn
in the centre.
The tyres must be replaced when the
tread comes to 1.6 mm thick. In any
case, follow the laws in force in the
country you are in.

WARNINGS
❒ Avoid braking suddenly, burning
starts and violent knocks against
the curb, potholes or other
obstacles if possible. Driving for
long stretches over uneven roads
can damage the tyres;
❒ periodically check that the tyres
have no cuts in the side wall,
abnormal swelling or irregular tread
wear. Contact a Fiat Dealership if
required;
❒ avoid overloading the car when
travelling: this may cause serious
damage to the wheels and tyres;
❒ if a tyre is punctured, stop
immediately and replace it to avoid
damage to the tyre, the rim,
suspension and steering system;
❒ tyres age even if they are not used
much. Cracks in the tread and on
the side walls are a sign of ageing.
In any event, have the tyres
checked by specialised personnel if
they have been fitted for longer than
6 years. Remember to check the
space-saver wheel very carefully;
❒ In the case of replacement, always
fit new tyres, avoiding those with an
unknown origin;
❒ if a tyre is replaced, also replace the
inflation valve;
❒ to allow even wear between the
front and rear tyres, it is advisable to
change them over every 10-15
thousand kilometres, keeping them
on the same side of the car so as
not to reverse the direction of
rotation.
