Wheels and tyres

To obtain the best
performances and the longest
mileage from the tyres,
comply with the following
precautions during the first 310 miles
(500 km):
- do not drive at maximum allowed
speed
- drive on curves at low speed
- avoid sudden steering
- avoid sudden braking
- avoid sudden accelerations
- do not drive at high speeds for too
long.
How to use the tyres
WARNING: The tyres must be
constantly kept in good conditions to
ensure safe driving.
The tyres' inflation pressure must
correspond to the prescribed values
and should be checked only when the
tyres have cooled down. In fact, the
pressure increases as the tyre
temperature progressively increases.
Never reduce the pressure if tyres are
hot.
Insufficient tyre inflating pressure can
cause tyre overheating and possible
internal damages, which may even
lead to the tyre destruction.
Check the inflating pressure of
the tyres when cold, at least
every two weeks and before
long trips.
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 structural damage
which is only visible when the tyre is
removed.
In any case, any possible damage must
be inspected by an experienced tyre
fitter, as it may seriously reduce the
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.
