tires Alfa Romeo Giulia 2018 Owner's Guide

Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately
1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage, especially in the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi
(21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to
6 psi (13 to 40 kPa) during operation.
DO NOT reduce this normal pressure
build up or your tire pressure will be too
low.Tire Pressures For High Speed
Operation
The manufacturer advocates driving at
safe speeds and within posted speed
limits. Where speed limits or conditions
are such that the vehicle can be driven at
high speeds, maintaining correct tire
inflation pressure is very important.
Increased tire pressure and reduced
vehicle loading may be required for
high-speed vehicle operation. Refer to
your authorized tire dealer or original
equipment vehicle dealer for
recommended safe operating speeds,
loading and cold tire inflation pressures.
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Recommended Cold Tire Inflation
Pressures
For vehicle speeds below 100 mph
(160 km/h), recommended cold tire
inflation pressures are listed on the Tire
And Loading Information Placard located
on driver’s side B-Pillar or the rear edge
of the driver's side door.
When driving at speeds 100 mph
(160 km/h) and above, increased tire
pressures and reduced vehicle loading
are required for high-speed vehicle
operation.
For driving speeds above 100 mph
(160 km/h) recommended cold tire
inflation pressures are listed below
under "High Speed Tire Inflation
Pressure". Vehicle loading condition
must not exceed 688 lbs. (312 kg)
(driver + three passengers + 88 lbs.
(40kg) luggage).
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision.

Radial Ply Tires
Warning!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability could
cause a collision. Always use radial ply tires
in sets of four. Never combine them with
other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
The tire has not been driven on when
flat.
The damage is only on the tread
section of your tire (sidewall damage is
not repairable).
The puncture is no greater than a ¼ of
an inch (6 mm).
Consult an authorized tire dealer for tire
repairs and additional information.
Damaged Run Flat tires, or Run Flat tires
that have experienced a loss of pressure
should be replaced immediately with
another Run Flat tire of identical size and
service description (Load Index and
Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to
drive 50 miles (80 km) at 50 mph
(80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is
referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat
mode it has limited driving capabilities
and needs to be replaced immediately.
A Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer
while a tire is in the run flat mode.
See the tire pressure monitoring section
for more information.

SERVICING AND MAINTENANCE

Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's
wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously
without stopping.
Warning!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin
your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds
continuously when you are stuck, and do not
let anyone near a spinning wheel, no matter
what the speed.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in
determining when your tires should be
replaced.These indicators are molded into the
bottom of the tread grooves. They will
appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced.
Refer to “Replacement Tires” in this
section for further information.Life Of Tire
The service life of a tire is dependent
upon varying factors including, but not
limited to:
Driving style.
Tire pressure - Improper cold tire
inflation pressures can cause uneven
wear patterns to develop across the tire
tread. These abnormal wear patterns will
reduce tread life, resulting in the need for
earlier tire replacement.
Distance driven.
Performance tires, tires with a speed
rating of V or higher, and Summer tires
typically have a reduced tread life. Rotation
of these tires per the vehicle scheduled
maintenance is highly recommended.
Warning!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place
with as little exposure to light as
possible. Protect tires from contact with
oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a
balance of many characteristics. They
should be inspected regularly for wear
and correct cold tire inflation pressures.
The manufacturer strongly recommends
that you use tires equivalent to the
originals in size, quality and performance
when replacement is needed. Refer to the
paragraph on “Tread Wear Indicators” in
this section. Refer to the Tire and Loading
Information placard or the Vehicle
0806104865NATire Tread
1 — Worn Tire
2 — New Tire
219

Certification Label for the size
designation of your tire. The Load Index
and Speed Symbol for your tire will be
found on the original equipment tire
sidewall.
See the Tire Sizing Chart example found
in the “Tire Safety Information” section of
this manual for more information relating
to the Load Index and Speed Symbol of a
tire.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling. If you ever
replace a wheel, make sure that the
wheel’s specifications match those of the
original wheels.
It is recommended you contact an
authorized tire dealer or original
equipment dealer with any questions you
may have on tire specifications or
capability. Failure to use equivalent
replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Warning!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index
or capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can result
in sudden tire failure and loss of vehicle
control.
Caution!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Spare Tires — If Equipped
Note: For vehicles equipped with Tire
Service Kit instead of a spare tire, please
refer to “Tire Service Kit” in “In Case Of
Emergency” for further information.
Caution!
Because of the reduced ground clearance,
do not take your vehicle through an
automatic car wash with a compact or
limited use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original
Equipped Tire And Wheel — If
Equipped
Your vehicle may be equipped with a
spare tire and wheel equivalent in look
and function to the original equipment
tire and wheel found on the front or rear
axle of your vehicle. This spare tire may
be used in the tire rotation for your
vehicle. If your vehicle has this option,
refer to an authorized tire dealer for the
recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary
emergency use only. You can identify if
your vehicle is equipped with a compact
spare by looking at the spare tire
description on the Tire and Loading
Information Placard located on the
driver’s side door opening or on the
sidewall of the tire. Compact spare tire
descriptions begin with the letter “T” or
“S” preceding the size designation.

SERVICING AND MAINTENANCE

When cleaning extremely dirty wheels
including excessive brake dust, care must
be taken in the selection of tire and wheel
cleaning chemicals and equipment to
prevent damage to the wheels. Select a
non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
Caution!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes or oven cleaner. These
products may damage the wheel's protective
finish. Such damage is not covered by the New
Vehicle Limited Warranty. Only car wash soap
is recommended.
Note:If you intend parking or storing your
vehicle for an extended period after
cleaning the wheels with wheel cleaner,
drive your vehicle and apply the brakes to
remove the water droplets from the brake
components. This activity will remove the
red rust on the brake rotors and prevent
vehicle vibration when braking.
Dark Or Low Gloss Wheels
Caution!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing compounds.
They will permanently damage this finish
and such damage is not covered by the New Vehicle Limited Warranty. HAND WASH
ONLY USING MILD SOAP AND WATER WITH
A SOFT CLOTH. Used on a regular basis; this
is all that is required to maintain this finish.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and
Winter). Traction levels may vary
between different all season tires. All
season tires can be identified by the M+S,
M&S, M/S or MS designation on the tire
sidewall. Use all season tires only in sets
of four; failure to do so may adversely
affect the safety and handling of your
vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice.
If your vehicle is equipped with Summer
tires, be aware these tires are not
designed for Winter or cold driving
conditions. Install Winter tires on your
vehicle when ambient temperatures are
less than 45°F (7°C) or if roads are covered
with ice or snow. For more information,
contact an authorized dealer.
Summer tires do not contain the all
season designation or mountain/
snowflake symbol on the tire sidewall.
Use Summer tires only in sets of four;
failure to do so may adversely affect the
safety and handling of your vehicle.
Warning!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the
use of snow tires during the Winter.
Snow tires can be identified by a
“mountain/snowflake” symbol on the tire
sidewall.
If you need snow tires,
select tires equivalent
in size and type to the
original equipment
tires. Use snow tires
only in sets of four;
failure to do so may
adversely affect the safety and handling
of your vehicle.
Snow tires generally have lower speed
ratings than what was originally equipped
with your vehicle and should not be
operated at sustained speeds over
75 mph (120 km/h). For speeds above
75 mph (120 km/h) refer to original
222
SERVICING AND MAINTENANCE

equipment or an authorized tire dealer
for recommended safe operating speeds,
loading and cold tire inflation pressures.
While studded tires improve
performance on ice, skid and traction
capability on wet or dry surfaces may be
poorer than that of non-studded tires.
Some states prohibit studded tires;
therefore, local laws should be checked
before using these tire types.
Tire Chains (Traction Devices)
Use of traction devices require sufficient
tire-to-body clearance. Follow these
recommendations to guard against
damage.
Note:
Traction device must be of proper
size for the tire, as recommended by the
traction device manufacturer
Use on Rear Tires Only
Due to limited clearance, the
following traction devices are
recommended:
For a 265/35R19 98V tire, use of a
zero-clearance snow traction device
recommended.
It is not possible to install traction
devices on 285/30R19 tires.
Caution!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important that
only traction devices in good condition are
used. Broken devices can cause serious
damage. Stop the vehicle immediately if
noise occurs that could indicate device
breakage. Remove the damaged parts of
the device before further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device
manufacturer’s instructions on the method
of installation, operating speed, and
conditions for use. Always use the
suggested operating speed of the device
manufacturer’s if it is less than 30 mph
(48 km/h).
Do not use traction devices on a compact
spare tire.
Tire Rotation Recommendations
Tire Rotations - Do Not Rotate Tires
Due to different size tires and wheels on
front and rear axles tire rotation is not
possible for:
2.9 L V6 Engine Equipped with 19”
tires and wheels
Caution!
Damage to the vehicle may occur if 19” front
and rear tires are rotated
In the case of irregular wear of the tires
identify the cause and correct it as soon
as possible, by contacting an authorized
dealer.

DEPARTMENT OF
TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety
Administration. The specific grade
rating assigned by the tire's
manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must
conform to Federal safety
requirements in addition to these
grades.
Treadwear
The Treadwear grade is a
comparative rating, based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well
on the government course as a tire
graded 100. The relative
performance of tires depends upon
the actual conditions of their use,
however, and may depart
significantly from the norm due tovariations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces
of asphalt and concrete. A tire
marked C may have poor traction
performance.
Warning!
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature Grades
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire failure. The
grade C corresponds to a level of
performance, which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of
performance on the laboratory test
wheel, than the minimum required by
law.
Warning!
The temperature grade for this tire
is established for a tire that is
properly inflated and not
overloaded. Excessive speed,
under-inflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.

SERVICING AND MAINTENANCE

STORING THE VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Park the vehicle in an area that is
covered and dry, and well-ventilated if
possible. Slightly open the windows.
Check that the electric park brake is
not activated.
Carry out the procedure: “manual trunk
opening device” procedure described in
this paragraph.
Disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage.
If the battery is not disconnected from
the electrical system, check its state of
charge every thirty days.
Clean and protect the painted parts
using protective wax.
Clean and protect the shiny metal
parts using special compounds available
commercially.
Sprinkle talcum powder on the
windshield wiper rubber blades, and lift
them off the glass.
Cover the vehicle with a fabric or
perforated plastic sheet, paying
particular care not to damage the painted
surface by dragging any dust that may
have accumulated on it. Do not use
compact plastic sheets, as they do not
allow humidity to evaporate from the
surface of the vehicle .
Inflate tires to +7.25 psi (+0.5 bar)
above the standard prescribed pressure
and check it periodically.
Do not drain the engine cooling
system.
Any time the vehicle is left inactive for
two weeks or more, operate the air
conditioning system with engine idling
for at least five minutes, setting external
air and with fan set to maximum speed.
This operation will ensure appropriate
lubrication for the system, thus
minimizing the possibility of damage to
the compressor when the system is
operated again.
Note: After cycling the ignition to STOP
and having closed the driver side door,
wait at least one minute before
disconnecting the electrical supply from
the battery. When reconnecting the
electrical supply to the battery, make
sure that the ignition is in the STOP
position and the driver side door is
closed. Manual Trunk Opening Device
Proceed as follows if the battery needs
to be disconnected:
1. From the trunk interior covering,
rotate the plug counterclockwise of the
lock and extract the cord connected to it.
