2010 Alfa Romeo GT tyres

IN AN EMERGENCY
187
Hand the instruction
brochure to the personnel
charged with treating the
tyre repaired with the kit.
In the event of a puncture
caused by foreign bodies, it
is possible to repair tyres
showing damages on the track or
shoulder up to max 4 mm diameter.IT SHOULD BE NOTICED THAT:
The sealing fluid of the quick tyre repair kit
is effective with external temperatures be-
tween –20°C and +50°C. The sealing flu-
id has limited life.
Holes and damages on
the tyre side walls cannot
be repaired. Do not use the
quick tyre repair kit if damaging
is due to running with flat tyre.
Repairs are not possible
in case of damages on the
wheel rim (bad groove dis-
tortion causing air loss). Do not re-
move foreign bodies (screws or
nails) from the tyre.The cylinder contains eth-
ylene glycol. The cylinder
contains latex: it can cause
allergic reactions. It is harmful if in-
gested or inhaled and irritant for
the eyes and in case of contact. In
case of contact rinse immediately
with water and take off contami-
nated clothes. If swallowed, do not
induce vomit, rinse out the mouth,
drink a lot of water and call the
doctor immediately. Keep away
from children. This product must
not be used by asthmatics. Do not
inhale vapours. Call the doctor im-
mediately in case of allergic reac-
tions. Keep the cylinder in the
space provided for the purpose and
far from heat. The sealing fluid has
limited life.

IN AN EMERGENCY
188
The compressor shall not
be operated for more than
20 minutes. Risk of over-
heating!. Tyres repaired with the
quick tyre repair kit shall be used
temporarily only.INFLATING PROCEDURE– loosen tyre inflation valve cap, take out
the filler hose A-fig. 14and screw the ring
nutB-fig. 15on the tyre valve;

Replace the cylinder if
sealer has run out. Do not
throw away the cylinder
and the sealing fluid. Have the
sealing fluid and the cylinder dis-
posed of in compliance with na-
tional and local regulations.
Put on the protection
gloves provided together
with quick tyre repair kit.
Proceed as follows:
– place the wheel with the valve A-fig.
13in the position shown in the figure then,
pull up the handbrake, take the repair
kit and put it on the ground near the in-
volved wheel;

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:
fig. 16
A0A0225b

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;

WHEELS
RIMS AND TYRES
Pressed steel or alloy rims.
Radial tubeless tyres.
The log book shows all the homologated
tyres.
IMPORTANTIn the event of any dis-
crepancies between this Handbook and the
vehicle Log Book, only the latter should be
considered.
While the specified dimensions remain the
same, for driving safety, the vehicle must be
fitted with tyres of the same brand and type
on all wheels.
IMPORTANTDo not use inner tubes
with Tubeless tyres.
COMPACT SPARE WHEEL
Pressed steel rim.
WHEEL GEOMETRY
Front wheel toe-in measured from rim to
rim: –1 ±0.6
