Wrong pressure causes uneven wear
of the tyres fig. 10:
A - Correct pressure: tyre wears
evenly.
B - Underinflated tyre: shoulder
tread wear.
C - Overinflated tyre: centre tread
wear.
If you get a flat tyre, stop immediately
and change it so as not to damage 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 side-walls are a sign of this
ageing. In any case, if the tyres have
been fitted for more than six years
they should be examined by an expert
who can judge whether they are still
fit for use. Remember to check the
spare tyre particularly carefully too.
If a replacement is necessary, always
use new tyres and avoid using ones the
origin of which you are not certain
about.
The Fiat barchetta uses Tubeless
tyres. Under no circumstances use an
inner tube with these tyres.
If you replace a tyre it is a good idea
to change the inflation valve, too.
Tyres must be replaced when the
tread wears down to 1.6 mm. 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 pavement,
potholes or other obstacles hard. Dri-
ving for long stretches over bumpy
roads can damage the tyres.
Periodically check that the tyres have
no cuts in the side wall, abnormal
swelling or irregular tyre wear. If any
of these occur, have the car seen to at
a Fiat Dealership.
Avoid travelling with an overloaded
car: this can seriously damage wheels
or tyres.

If the pressure is too low
the tyre overheats and this
can cause it serious damage.
