❒ In the case of replacement, always fit new tyres,
avoiding those of dubious origin;
❒ if a tyre is changed, also change the inflation
valve.
WARNING
The road holding qualities of the car
also depend on the correct inflation
pressure of the tyres.
WARNING
If the pressure is too low the tyre
overheats and this can cause it
serious damage.
WARNING
Do not cross switch the tyres, moving
them from the right of the car to the
left and vice versa.
WARNING
Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
