Wheels And Tyres - Fiat 500 C Owner's Handbook Manual

WHEELS AND TYRES

40)
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" section.
Incorrect pressure causes abnormal
tyre wear fig. 143:
A standard 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 all
cases, follow the laws in force in the
country where you are driving.

IMPORTANT
❒ Avoid braking suddenly, high-
powered starts and violent impacts
against curbs, 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.
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 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 sidewalls 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.
Also remember to check the space-
saver wheel with particular care;
❒ In the case of replacement, always
fit new tyres, avoiding those with an
unknown origin;
❒ If a tyre is replaced, 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 car to avoid
inverting the direction of rotation.
❒ avoid travelling with partially or
completely deflated tyres as this can
compromise safety and damage the
tyres beyond repair.
