IMPORTANT Using snow chains with
tyres with non-original dimensions may
damage the vehicle.
IMPORTANT Using different size or type
(M+S, snow, etc.) tyres between front and
rear axle may adversely affect vehicle
driveability, with the risk of losing control
of the vehicle and resulting accidents.
SUGGESTIONS ABOUT THE ROTATION
OF THE TYRES
The front and rear tyres are subject to
different loads and stress due to
steering, manoeuvres and braking. For
this reason they are subject to uneven
wear.
To prevent this problem, the tyres should
be rotated at the appropriate time (6000
/ 9000 mi (10000 / 15000 km)).
Inverting the tyres means moving them
to different positions on the same side of
the car (front to back and vice versa).
IMPORTANT Crossing the tyres is not
advised, so placing a tyre on a different
axle on the other side of the car is
impossible.
IMPORTANT On cars equipped with
differentiated tyres (tyre size different
between front and rear axles, ex. QV
version) rotation of any of the tyres is not
advised.
174
Tyre rotation contributes to the
preservation of the grip and traction
performance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting an Alfa Romeo
Dealership.
All Wheel Drive (AWD) versions
It is recommended to avoid situations
with a large difference in wear between
the front and rear tyres and to strictly
use winter tyres of the sizes given in the
"Rims and tyres provided" table.
The AWD systems and the original tyres
were developed together to ensure the
vehicle's best performance. When
changing the tyres, it is therefore
recommended to use the same "AR"
marked tyres, to maintain the same level
of performance and component life.
WARNING
164) The road holding qualities of the car
also depend on the correct inflation pressure
of the tyres.
165) If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
166) Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
IMPORTANT
80) Keep your speed down when snow chains
are fitted; do not exceed 50 km/h (or the
equivalent in miles). Avoid potholes, do not
drive over steps or sidewalks and do not
drive long distances over roads without
snow, to avoid damaging both your vehicle
and the road surface.
