Tyres and rims
Checking the state of the tyres
Tyre replacement is recommend after 4 years of normal use. Frequent use in maximum load conditions
and at high temperatures may lead to premature deterioration.
Check the state of the tyres during the scheduled maintenance.
CAUTION
Pressure increases with increasing tyre temperature. Never reduce the tyre pressure if measured when the
tyres are hot.
Tyre overheating due to underinflation may seriously compromise handling and tyre integrity.
Do not inflate the tyres to a pressure other than the specified value, as this would render the tyre pressure
monitoring system useless.
After replacing one or more tyres, always calibrate the tyre pressure monitoring system by pressing the button
on the passenger compartment dome light panel.
Check the inflation pressure: pressure must be measured with cold tyres and must match the values specified.
CAUTION
Always inspect any tyre damage very carefully to assess severity: damage may greatly reduce tyre life and
cause accidents.
Check the tyres to ensure that there are no signs of damage such as abrasion, cuts, cracks, bubbles etc.
Violent knocks against kerbs, holes or other obstacles and driving on poor road surfaces for extended periods
may cause tyre damage. This damage may not always be visible. Any foreign objects penetrating the tyre
in these conditions may cause structural damage that is only identifiable after removing the tyre from the
wheel.
CAUTION
If the same tyres have been fitted on the vehicle for over 3 years, check frequently and carefully for signs of
deterioration.
Do not monitor the pressure of a damaged tyre.
Tyres will deteriorate even if the vehicle is used rarely or kept stationary. Cracks in the rubber on the tread
and sidewalls, at times accompanied by blisters, are an indication of tyre deterioration.
