Wheels And Tyres - Ferrari 575M Superamerica Owner's Manual

CHECKS AND MAINTENANCE

WHEELS AND TYRES

To ensure performance, endurance and
the best tyre adjustment on the rim, it is
important to comply with the following
instructions for the first 200-300 km of
use of new tyres:
• avoid sudden acceleration;
• avoid sharp braking and steering turns;
• drive at moderate speed on straight
roads and on curves.
How to use the tyres
7
The tyres must be constantly kept in good
conditions to ensure safe driving.
The inflation pressure must correspond
to the specified values and the tyres
should be checked only when they are
cold. Tyre pressure increases as the tyre
temperature progressively increases.
Never reduce the pressure if the tyres are
hot.
Insufficient tyre pressure can lead
to overheating, damage and even
destruction of the tyres.
154
CAUTION
Inflating the tyres to a pressure
differing from that prescribed (see
table on page 16) will render the
monitoring system inefficient.
Violent impact against sidewalks, pot
holes in the road and other obstacles of
various types, as well driving on rough
roads for long periods of time may cause
damage to the tyres which may not
always be visible.
Check the tyres regularly for any signs of
damage (e.g., scratches, cuts, cracks,
bulges, etc.).
Sharp objects that have penetrated the
tyres may have caused damage which can
only be diagnosed by removing the tyre.
Have any damage inspected by an expert
as it may considerably reduce tyre life.
Remember that tyres deteriorate with
time, even if used little or not at all.
Cracks in the tread and sidewalls,
possibly accompanied by bulging, are
sure signs of ageing.
Have the tyres replaced by the Ferrari
Service Network where they have the
necessary tools and equipment available,
in order to prevent that an improper or
careless service operation damages the
sensor inside the wheel rim.
Have a skilled technician decide whether
old tyres are suitable for use. In any case,
tyres that have remained on a vehicle for
more than 3 years must be checked by
skilled personnel.
Never fit tyres of uncertain origin.
CAUTION
The tyres are of the "unidirectional"
type and there is an arrow on the
side indicating the rolling direction
or the outside. When changing the
tyres, ensure that the rolling direction
corresponds to that indicated, in order
to maintain optimal performance.
Tyres on the same axle must always be
replaced in pairs.
