Tires Maintenance
CAUTION!
To obtain the best performances and
the longest mileage from the tires, take
following precautions during the first 310
mi (500 km):
•
do not drive at the vehicle’s maximum
speed;
•
drive at low speed on curves;
•
avoid sudden steering;
•
avoid sudden braking;
•
avoid sudden acceleration;
•
do not drive at high speeds for too
long.
The tires inflation pressure must
correspond to the prescribed values
(see chapter "Tire Inflation Pressure" in
section "Technical Specifications") and
should be checked only when the tires
have cooled down. In fact, the pressure
increases as the tire temperature
progressively increases.
Never reduce the pressure if tires
are hot (see chapter "Tires - General
Information" in section "Understanding
the Vehicle").
Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage, which may even lead to
the tire destruction.
CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
could damage it.
Impacts with curbs, holes, and obstacles
in the road, and prolonged trips on rough
roads can cause tire damage which may
not be visible to the naked eye.
Check your tires regularly for any signs
of damage (e.g. scratches, cuts, cracks,
bulges, etc.). If sharp objects penetrate
the tires, they can cause structural
damage which is only visible when the
tire is removed.
In any case, any possible damage must
be inspected by an experienced tire
fitter, as it may seriously reduce the tire
life.
Remember that tires deteriorate with
time, even if used little or not at all.
Cracks in the tire tread and sides,
alongside possible bulging, are a sign of
deterioration.
WARNING!
•
Check the inflating pressure of the
tires when cold, at least every two
weeks and before long trips.
•
Have the old tires inspected by an
experienced technician, to make sure
they can still be used safely. If the
same tire has been on your vehicle for
4 or 5 years, have it inspected anyway
by an experienced technician.
•
Never fit tires of uncertain origin.
•
"Directional" tires have an arrow on
their side showing the rolling direction.
To keep the best performance when
replacing a tire, make sure that the
rolling direction corresponds to the
one shown by the arrow.
•
During the tire life, the rolling
direction used for the first fitting shall
always be observed, also in case of
"nondirectional" tires.
•
Check the depth of the tire tread
at regular intervals. The minimum
allowed value is 0.06 in (1.6 mm) or
0.16 in (4 mm) for winter and snow
tires, at that point the wear indicators
on the tire will be visible (see chapter
“Tires - General Information” in section
“Understanding the Vehicle”). The
thinner is the tread, the greater is the
risk of skidding.
