Impacts with kerbs, holes, and
obstacles in the road, and prolonged
trips on rough roads can cause tyre
damage which may not be visible to
the naked eye.
Check your tyres regularly for any
signs of damage (e.g. scratches, cuts,
cracks, bulges, etc.).
If sharp objects penetrate the tyres,
they can cause damage which is only
visible when the tyre is removed.
In any case, any possible damage must
be inspected by an experienced tyre
fi tter, as it may seriously reduce tyre
life.
Remember that tyres deteriorate with
time, even if used little or not at all.
Cracks in the tyre tread and sides,
alongside possible bulging, are a sign
of deterioration. Have the old tyres inspected
by an experienced tyre fi tter,
to make sure they can still
be used safely. If the same tyre has
been on your vehicle for 4 or 5 years,
have it inspected anyway by an
experienced tyre fi tter.
Never fi t tyres of uncertain
origin.
“Directional” tyres have an
arrow on their side showing
the rolling direction. To keep
the best performance when replacing
a tyre, make sure that the rolling
direction corresponds to the one
marked by the arrow.
During the tyre life the
rolling direction of the
fi rst fi tting shall always
be observed, also in case of “non-
directional” tyres.
Check the depth of the tyre
tread at regular intervals
(minimum allowed value 1,6
mm - 0.06 in). The thinner is the tread,
the greater is the risk of skidding.
Drive carefully on wet
roads to decrease the risk of
aquaplaning.
