Care of the vehicle
Never reduce the pressure if the tyres are hot.
Environment
Periodically check the tyre pressure. Driving with the
tyres inflated to the correct pressure helps to reduce fuel
consumption.
Low tyre pressure can lead to overheating, internal damage and
even destruction of the tyres.
Warning
Inflating the tyres to a pressure other than the specified value
will render the TPMS monitoring system ineffective.
Sudden impact with pavements, potholes and other obstacles of
various types as well as long trips on rough roads can cause damage
to the tyres that is not always visible to the naked eye.
Check the 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.
Have any damage inspected by an expert as it may considerably
reduce tyre life.
Remember that tyres deteriorate over time even if they are rarely
used or not used at all.
Cracks in the tread and side walls, possibly accompanied by
bulging, are sure signs of ageing.
Warning
The maximum speed supported by the winter tyres (see
page 31) is lower than that supported by the summer tyres.
Always check the maximum speed rating indicated on the tyre
by the tyre manufacturer.
Warning
The Ferrari Service Network is suitably equipped to replace
tyres, and to determine whether a tyre is safe for use.
Have the tyres replaced by the Ferrari Service Network that
has the necessary equipment available to avoid causing damage
through carelessness to the sensor located inside the wheel rim
(on vehicles with the tyre temperature and pressure monitoring
system - TPMS).
Important note
The Ferrari Service Network can certify whether aged tyres
are suitable for use.
Warning
Replace the tyres at intervals no longer than 4 years of normal
usage, even if the maximum mileage specified has not been
exceeded.
