tyre pressure Alfa Romeo GT 2008 Owner handbook (in English)

CAR MAINTENANCE
233
Incorrect pressure causes abnormal tyre
wear:
(A): normal pressure: tread evenly worn.
(B): low pressure: tread particularly worn
at the edges.
(C): high pressure: tread particularly worn
in the centre.
Tyres should be changed when the tread
thickness is reduced to 1.6 mm.
In any case follow local regulations.
You are also reminded that services with
high current absorption switched on by the
user, such as for example: baby bottle warm-
ers, vacuum cleaner, mobile phone, mini
fridge, etc., quicken the battery drain-
ing processif they are turned on with the
engine off or running at idle speed.
IMPORTANTWhen installing addition-
al systems on the car, bear in mind that im-
proper branches on connections of the car
wiring are dangerous, particularly if safety
devices are involved.
WHEELS AND TYRES
TYRE PRESSURE
Check the tyre pressure of every wheel, in-
cluding the spare, every two weeks and be-
fore 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; for the correct tyre
inflation pressure, see “Wheels” in the
“Technical Specifications” chapter.
Battery
60 Ah
70 AhMaximum permissible
loadless absorption
36 mA
42 mA
The maximum absorption of all the ac-
cessories (standard and fitted afterwards)
should be 0,6 mA x Ah (of the battery), as
shown in the following table:

CAR MAINTENANCE
234
Alloy rim painting involv-
ing temperatures exceed-
ing 150 °C should be
avoided since wheel mechanical
characteristics could be impaired. Do not cross switch the
tyres, moving them from
the right of the car to the
left and vice versa.Excessive low pressure
causes overheating of the
tyre with the possibility of
serious damage to it.Remember that car road
holding also depends on
correct tyre inflation pres-
sure.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully fol-
low the Scheduled Maintenance Pro-
gramme. Indeed, ozone, high temperatures
and the prolonged lack of fluid in the sys-
tem may cause hardening and cracking of
the hoses, with possible leaks. Careful con-
trol is therefore necessary.
IMPORTANT NOTES
– Where possible, avoid sudden braking,
tyre squealing starts, 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 Authorised Ser-
vices;
– Avoid overloading the car when travel-
ling: this may cause serious damage to the
wheels and tyres;
– If a tyre is punctured, stop immediate-
ly and change it to avoid damage to the tyre
itself, the rim, suspensions and steering sys-
tem;
– Tyres age even if they are not used
much. Cracks in the tread rubber are a sign
of aging. 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 compact spare wheel;
– In case of replacement, always fit new
tyres, avoiding those of dubious origin;
