In the case of replacement, always fit new
tyres, avoiding those of dubious origin.
Alfa 156uses Tubeless tyres. Never
use an inner tube with these tyres.
If a tyre is changed, also change the in-
flation valve
To allow even wear between the front and
rear tyres, it is advisable to change them
over every 10-15 thousand kilometres,
keeping them on the same side of the car
so as to not reverse the direction of rotation
(fig. 26).
RUBBER HOSESAs far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully fol-
low the Scheduled Maintenance Programme
of this chapter. Indeed ozone, high tem-
peratures and prolonged lack of fluid in the
system may cause hardening and cracking
of the hoses, with possible leaks. Careful
control is therefore necessary.
Do not cross switch the
tyres, moving them from
the right of the car to the left and
vice versa.
WARNING
Alloy rim painting involv-
ing temperatures exceed-
ing 150°C should be avoided since
wheel mechanical characteristics
could be impaired.

SPARK PLUGClean, intact spark plugs are determinant
with regard to engine efficiency and for re-
ducing the emission of pollutants.Spark plugs should be re-
placed at the intervals
specified in the Scheduled
Maintenance Programme. Only use
spark plugs of the specified type: if
the thermal capacity is inadequate
or if the envisaged life is not guar-
anteed inconveniences may ensue.BRAKESService brakes:
– front
– rearParking brake
If examined by an expert eye, the ap-
pearance of a spark plug is a sound clue
for locating a fault, even if not involving the
ignition system. Therefore if you are expe-
riencing any engine problems, it is impor-
tant to have the spark plugs checked by Al-
fa Romeo Authorized Services.
