WHEELS AND TYRES
Check the pressure of each
tyre including the spare 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 vehicle is used; for the
correct tyre inflation pressure, see the
"Wheels" chapter in the "Technical
Specifications" section.
Incorrect pressure causes abnormal
tyre wear fig. 334:
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 is less than 1.6 mm thick. In any
case, follow the laws in force in the
country where you are driving.

WARNINGS
As far as possible, avoid sharp
braking, screech starts and violent
shocks against pavements, potholes or
other hard obstacles.
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 tyre tread wear. Go
to 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 charge it to
avoid damage to the tyre, the rim,
suspensions and steering system;
tyres age even if they are not used
much. Cracks in the tread and on
the sidewalls are a sign of ageing. In
any event, have the tyres checked by
specialised technicians if they have
been fitted for longer than 6 years.
Remember to check the spare wheel
very carefully;
in the case of replacement, always fit
new tyres, avoiding those of unknown
origin;
if a tyre is changed, also change 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 vehicle so as not to reverse
the direction of rotation.
WARNING Replacing a tyre, check that
the tyre pressure monitoring (TPMS)
sensor is also taken from the previous
rim, together with the valve.
WARNING
235) Remember that the road holding
qualities of your vehicle also depend on
the correct inflation pressure of the tyres.
236) If tyre pressure is too low, the tyre
may overheat and be severely damaged as
a result.
237)
Do not switch tyres from the
right­hand side of the vehicle to the
left­hand side, and vice versa.
238)
Do not repaint alloy wheel rims at
temperatures higher than 150
°
