Wheels and tires

Have the old tires inspected
by an experienced tire person,
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
tire person. Always follow the tire
manufacturer’s recommendations.
Never fit tires of uncertain
origin.
“Directional” tires have an
arrow on their sidewall
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 “non-
directional” tires.
Check the depth of the tire
tread at regular intervals
(minimum allowed value
0.063 in / 1.6 mm). The thinner is the
tread, the greater is the risk of
skidding.
Drive carefully on wet roads
to decrease the risk of
aquaplaning.
