How to use the tires
WARNING: The tires must be
constantly kept in good conditions to
help ensure safe driving. Always check
your tires regularly for tread wear.
The tires inflation pressure must
correspond to the prescribed values
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.
Insufficient tire inflating pressure can
cause tire overheating and possible
internal damages, which may even
lead to the tire destruction.
Check the inflating pressure of
the tires when cold, at least
every two weeks and before
long trips.
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
personnel, 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 sidewalls,
alongside possible bulging, are a sign
of deterioration.
