Wheels And Tyres; Tyres Pressure - Alfa Romeo 156 Owner's Manual

WHEELS AND TYRES

TYRES PRESSURE

Check the pressure of each tyre, includ-
ing the compact spare wheel, every two
weeks and before a long journey.
The pressure should be checked with the
tyre rested and cold.
It is normal for the pressure to increase
when the car is in use. If you have to check
or restore the pressure when the tyres are
hot, bear in mind that the pressure should
be +0.3 bar compare with the specified rat-
ing.
For the correct tyre inflation pressure, see
"Wheels" in the "Technical specifications"
chapter.
WARNING
Remember that car road
holding also depends on
correct tyre inflation pressure.
Incorrect pressure causes abnormal tyre
wear fig. 25:
A - Normal pressure: tread evenly worn.
B - Low pressure: tread particularly worn
at the edges.
C - High pressure: tread particularly worn
in the centre.
WARNING
Excessively low pressure
causes overheating of the
tyre with the possibility of serious
damage to it.
Tyres should be changed when the tread
thickness is reduced to 1.6 mm. In any case
follow local regulations.

WARNINGS
Where possible, avoid sudden braking, tyre
squealing starts, etc.
Particularly avoid violent bumps against
kerbs, potholes or obstacles of various kinds.
Prolonged driving on rough roads may dam-
age the tyres.
Routinely check the tyres for cuts on the
sides, swellings or uneven tread wear. If nec-
essary contact Alfa Romeo Authorized Ser-
vices.
Avoid overloading the vehicle when trav-
elling: this may cause serious damage to the
wheels and tyres.
If a tyre is punctured, stop immediately
and change it to avoid damage to the tyre,
the rim, suspensions and steering system.
Tyres age even if they are not used much.
Cracks in the tread rubber are a sign of ag-
ing. In any case, if the tyres have been on
the car for over 6 years, they should be

checked by specialised personnel, to see if
they can still be used. Also remember to
check the spare wheel.
