Note for one way tyres
There are arrows on the side of one-way
tyres indicating the direction of rotation.
When a wheel is changed (for example
after a puncture, the direction of the ar-
row on the spare wheel might not coin-
cide with the direction of rotation of the
wheel to be changed. Even in these con-
ditions the tyre is still safe but you are ad-
vised to have the tyre repaired and refit-
ted as soon as possible, because top per-
formance is obtained when all the wheels
turn in the direction of the arrow.

Note The vehicles are fitted with tube-
less tyres. See chapter "Getting the best
out of your car" for indications concerning
tyres in general and the specific recom-
mendations for tubeless tyres. When re-
placing tyres and/or rims maintain the o-
riginal rim/tyre match.
IMPORTANT Tyre pressure should be
increased by 0.3 bars when driving at
sustained high speed. With winter tyres
the pressure should be +0.2 bar higher
than the rating specified for standard
tyres. Do not use inner tubes with tube-
less tyres.
Snow chains can be fitted
only on wheels with 6.5J x
16" rims and 215/55 R16
(*) tyres or 7.5J x 17" rims and
