Incorrect pressure causes abnormal tyre
wearfig. 17:
Anormal pressure: tread evenly worn.
Blow pressure: tread particularly worn
at the edges.
Chigh pressure: tread particularly worn
in the centre.
Tyres must be replaced when the tread
wears down to 1.6 mm. In any case,
comply with the laws in the country
where the car is being driven.
IMPORTANT NOTES
As far as possible, avoid sharp braking
and screech starts, etc. Be careful not to
hit the kerb, potholes or other obstacles
hard. Driving for long stretches over
bumpy roads can damage the tyres.
Periodically check that the tyres have no
cuts in the side wall, abnormal swelling
or irregular tyre wear. If any of these oc-
cur, have the car seen to at Alfa Romeo
Authorized Services.
Avoid overloading the car when travel-
ling: this may cause serious damage to
the wheels and tyres; if a tyre is punc-
tured, stop immediately and change it
to avoid damage to the tyre, the rim,
suspensions and steering system.
WHEELS AND TYRES
Check the pressure of each tyre, includ-
ing the space-saver spare wheel, every
four weeks and before long journeys:
pressure should be checked with the tyre
rested and cold.
For the correct tyre inflation pressure,
see “Wheels” in “Technical specifica-
tions” section.

COLD TYRE INFLATION PRESSURE
(▼) Unchainable tyres. Size certified and admitted only for PIRELLI 235/40 ZR19 96Y. When using winter tyres, use 225/50 ZR17 96 tyres or
235/45 R18 98. Vehicles with TI fittings should not use 16” wheel rims.
Add +0.3 bar to the prescribed inflation pressure when the tyres are warm. Recheck pressure value with cold tyres.
With snow tyres, add +0.2 bar to the inflation pressure value prescribed for standard tyres.
Inflate tyres to full load pressures if driving at continuous speed exceeding 160 km/h.Space-saver
