TIRE EQUIPMENT
The GT-R summer tires are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F(08C) so you
must drive carefully. NISSAN recommends the
use of winter or all-season tires on all four
wheels if you plan to operate your vehicle in
snowy or icy conditions when temperatures are
less than 328F(0 8C) .
WARNING
Never use summer tires when the
temperature is below −48F(−208C) to
prevent permanent tread deformation
which may cause tire damage or tire
failure. This may cause a loss of vehicle
control which can result in serious
personal injury or death.
Tire chains may be used. (
“Tire chains”
page 8-40)
If you install tires, they must also be the specified
size, brand, construction and tread pattern on all
four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
. A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
. A sturdy, flat board to be placed under the
jack to give it firm support.
. A shovel to dig the vehicle out of snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
.Wet ice (328F, 0 8C and freezing rain) ,
very cold snow or ice can be slick
and very hard to drive on. The
vehicle will have much less traction
or “grip” under these conditions. Try
to avoid driving on wet ice until the
road is salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction. .
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a
patch of ice is seen ahead, brake
before reaching it. Try not to brake
while on the ice, and avoid any
sudden steering maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
NOTE:
When driving on snow, select the SAVE
mode with the setup switch. By selecting
the SAVE mode, the engine output is
controlled appropriately for snow or slip-
pery road surfaces. This enables the vehi-
cle to start or accelerate smoothly.

8-4Maintenance and do-it-yourself
During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have a
GT-R certified NISSAN dealer do it promptly. In
addition, you should notify a GT-R certified
NISSAN dealer if you think that repairs are
required. (
“Maintenance precautions”
page 8-6)
EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood: Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently. Lights*:
Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires cannot be rotated because
your vehicle is equipped with different sized tires
in the front and rear.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires to the
pressure specified. Check carefully for damage,
cuts or excessive wear.
NOTE:
. You can check the pressure of all four
tires on the multi function display. See
the separate Multi Function Display
Owner’s Manual.
. The tires of this vehicle are filled with
nitrogen gas. When the tire pressure is
low, fill the tires with nitrogen. Contact
a GT-R certified NISSAN dealer for
information on filling the tires with
nitrogen. .
If nitrogen is not available, compressed
air may be safely used under normal
driving conditions. However, NISSAN
recommends refilling with nitrogen for
maximum tire performance.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace grommet
seal of transmitter in TPMS, when replacing
each tire by reaching the wear limit.
Tire, wheel alignment and balance: If the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet.
Windshield: Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
GENERAL MAINTENANCE

rigid side wall. Special techniques and
equipment are therefore required when
replacing these tires. NISSAN recom-
mends that tire replacement be per-
formed at a GT-R certified NISSAN
dealer.
. Specific tire changing equipment must
be used to remove the GT-R tires from
the wheel and to install the GT-R tires
onto the wheel. It is only possible to
reuse the tires when they have no
cracks and/or deformations on the
bead portion of the tire. If the incorrect
equipment is used to remove the GT-R
tires from the wheel and to install the
GT-R tires onto the wheel, cracks and
deformation may occur on the bead
portion of the tires meaning that the
tires cannot be reused. Contact a GT-R
certified NISSAN dealer if the tires
need to be removed from the wheels.TIRE AND LOADING INFORMATION LABEL
*1Seating capacity: The maximum number
of occupants that can be seated in the
vehicle.
*2Vehicle load limit: See the following
section. (
“Vehicle loading informa- tion” page 9-14)
*3Original size: The size of the tires
originally installed on the vehicle at the
factory.

*4Cold tire pressure: Inflate the tires to
this pressure when the tires are cold.
Tires are considered COLD after the
vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6
km) at moderate speeds. The recom-
mended cold tire inflation is set by the
manufacturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the
vehicle’s GVWR.

1.Remove the valve stem cap from the
tire.
2.Press the pressure gauge squarely onto
the valve stem. Do not press too hard or
force the valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard while
checking the pressure, reposition the
gauge to eliminate this leakage.
3.Remove the gauge.
4.Read the tire pressure on the gauge
stem and compare it to the specifica-tion shown on the Tire and Loading
Information label.
5.Add air to the tire as needed. If too
much air is added, press the core of the
valve stem briefly with the tip of the
gauge stem to release pressure. Re-
check the pressure and add or release
air as needed.
6.Install the valve stem cap.
7.Check the pressure of all other tires.
NOTE:
.
You can check the pressure of all
four tires on the multi function
display. See the separate Multi
Function Display Owner’s Manual.
.The tires of this vehicle are filled
with nitrogen gas. When the tire
pressure is low, fill the tires with
nitrogen. Contact a GT-R certified
NISSAN dealer for information on
filling the tires with nitrogen.
.If nitrogen is not available, com-
pressed air may be safely used
under normal driving conditions.

Example
TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental character-
istics of the tire and also provides the tire
identification number (TIN) for safety stan-
dard certification. The TIN can be used to
identify the tire in case of a recall.
Example
1.Tire size (example: P215/65R15 95H)
a.P: The “P” indicates the tire is designed for passenger vehicles.
(Not all tires have this information.)
b.Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
c.Two-digit number (65): This number, known as the aspect ratio, gives the
tire’s ratio of height to width.
d.R: The “R” stands for radial.
e.Two-digit number (15): This number

is the wheel or rim diameter in
inches.
f.Two- or three-digit number (95): Thisnumber is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires
because it is not required by law.
g.H: Tire speed rating. You should notdrive the vehicle faster than the tire
speed rating.
Example
2.TIN (Tire Identification Number) for a
new tire (example: DOT XX XX XXX
XXXX)
a.DOT: Abbreviation for the “Depart- ment of Transportation”. The symbol
can be placed above, below or to the
left or right of the Tire Identification
Number.
b.Two-digit code: Manufacturer’s iden-tification mark
c.Two-digit code: Tire size
d.Three-digit code: Tire type code(Optional)
e.Three-digit code: Date of Manufac-
ture
f.Four numbers represent the week and year the tire was built. For
example, the numbers 3103 means
the 31st week of 2003. If these
numbers are missing, then look on
the other sidewall of the tire.
3.Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire.
Tire manufacturers also must indicate
the materials in the tire, which include
steel, nylon, polyester, and others.
4.Maximum permissible inflation pressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum
permissible inflation pressure.
5.Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as the
factory installed tire.
Maintenance and do-it-yourself8-37

8-38Maintenance and do-it-yourself
6.Term of “tubeless” or “tube type”
Indicates whether the tire requires an
inner tube (“tube type”) or not (“tube-
less”) .
7.The word “radial”
The word “radial” is shown, if the tire
has radial structure.
8.Manufacturer or brand name
Manufacturer or brand name is shown.
Other tire-related terminology:
In addition to the many terms that are
defined throughout this section, Intended
Outboard Sidewall is (1) the sidewall that
contains a whitewall, bears white lettering
or bears manufacturer, brand and/or model
name molding that is higher or deeper than
the same molding on the other sidewall of
the tire, or (2) the outward facing sidewall
of an asymmetrical tire that has a particular
side that must always face outward when
mounted on a vehicle.
TYPES OF TIRES
WARNING
. When changing or replacing tires,
be sure all four tires are of the same
type (Examples: Summer or All
Season) and construction. A GT-R
certified NISSAN dealer may be able
to help you with information about
tire type, size, speed rating and
availability.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in the
Warranty Information Booklet.
All-season tires
NISSAN specifies all-season tires on some
models to provide good performance for use
all year around, including snowy and icy road
conditions. All-season tires are identified by ALL
SEASON on the tire sidewall.
Summer tires
The GT-R summer tires are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F(0 8C) so you
must drive carefully. NISSAN recommends the
use of winter or all-season tires on all four
wheels if you plan to operate your vehicle in
snowy or icy conditions when temperatures are
less than 328F(0 8C) .
WARNING
Never use summer tires when the
temperature is below −48F(−208C) to
prevent permanent tread deformation
which may cause tire damage or tire
failure. This may cause a loss of vehicle
control which can result in serious
personal injury or death.
Run-flat tires
Your vehicle is equipped with run-flat tires. You
can continue driving to a safe location even if
they are punctured. Always use run-flat tires of
the specified size on all four wheels. Mixing tire
sizes or construction may reduce vehicle hand-

8-40Maintenance and do-it-yourself
Tires for All-Wheel Drive (AWD)
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the specified size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact a GT-R certified
NISSAN dealer.
TIRE CHAINS
Use of tire chains may be prohibited according
to location. Check the local laws before instal-
ling tire chains. When installing tire chains, make
sure they are of proper size for the tires on your
vehicle and are installed according to the chain
manufacturer instructions.Use only SAE class
S chains. Class “S” chains are used on vehicles
with restricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed to
meet the SAE standard minimum clearances
between the tire and the closest vehicle
suspension or body component required to
accommodate the use of a winter traction device
(tire chains or cables) . The minimum clearances
are determined using the factory equipped tire
size. Other types may damage your vehicle. Use
chain tensioners when recommended by the tire
chain manufacturer to ensure a tight fit. Loose
end links of the tire chain must be secured or removed to prevent the possibility of whipping
action damage to the fenders or undercarriage.
If possible, avoid fully loading your vehicle when
using tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be da-
maged and/or vehicle handling and performance
may be adversely affected.
NOTE:
Tire chains must be installed only on the
rear wheels and not on the front wheels.
CAUTION
Do not use tire chains on dry roads.
NOTICE
Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
Do not drive with tire chains on paved roads that
are clear of snow. Driving with chains in such
conditions can cause damage to the various
mechanisms of the vehicle due to some
overstress.
CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated because your
vehicle is equipped with different sized
tires in the front and rear.

Tire wear and damage
WARNING
.Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.
.The original tires have built-in
tread wear indicators. When thewear indicators are visible, the
tire(s) should be replaced.
.Tires degrade with age and use.
Have tires, over 6 years old
checked by a qualified techni-
cian because some tire damage
may not be obvious. Replace the
tires as necessary to prevent tire
failure and possible personal
injury.
.For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Replacing wheels and tires
When tire replacement is required, replacing
tires as a set of four with new tires is
recommended. However, if a tire is punctured
or damaged, it may be possible to replace only
the damaged tire. Determining whether one tire
or a complete set of tires should be replaced is
based on a number of factors including tire wear
and condition. Contact your GT-R certified NISSAN dealer. They can recommend if an
individual tire or a complete set should be
replaced.
When replacing a tire, use the specified size,
speed rating and load carrying capacity as
originally equipped. (
“Wheels and tires”
page 9-9)
NOTICE
. When you replace the GT-R tires, it
is recommended that you replace all
the tires at the same time.
. The GT-R uses specially designed
run-flat tires which feature an ex-
tremely rigid side wall. Special tech-
niques and equipment are therefore
required when replacing these tires.
NISSAN recommends that tire re-
placement be performed at a GT-R
certified NISSAN dealer.
. When tires are reinstalled after
being uninstalled from the wheels,
use equipment such as a leverless
automatic tire changer. It is only
possible to reuse the tires when
they have no cracks and/or defor-
mations on the bead portion. How-
ever, if you use a lever-type tire
Maintenance and do-it-yourself8-41

8-42Maintenance and do-it-yourself
changer, cracks and deformation
may occur on the bead portion of
the tires meaning that the tires
cannot be reused.
. Make sure the tire valve stem cap is
installed and that the valve stem is
tight. When installing the cap, make
sure to tighten the cap by hand. If a
tool is used to tighten the cap, the
cap may be damaged.
WARNING
.The use of tires other than those
specified or the mixed use of tires of
different brands, construction (bias,
bias-belted, radial or run-flat) , or
tread patterns can adversely affect
the ride, braking, VDC system, hand-
ling, ground clearance, body-to-tire
clearance, tire chain clearance,
speedometer calibration, headlight
aim and bumper height. Some of
these effects may lead to accidents
and could result in serious personal
injury.
. If the wheels are changed for any
reason, always replace with wheels which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics, affect the VDC system and/or
cause interference with the brake
discs. Such interference can lead to
decreased braking efficiency and/or
early brake pad wear. (
“Wheels
and tires” page 9-9)
. When a wheel is replaced, tire
pressure will not be indicated, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute and
remain on after the 1 minute. Con-
tact a GT-R certified NISSAN dealer
as soon as possible for tire replace-
ment and/or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning. .
Never use retread tires.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in the
Warranty Information Booklet.
. Always use tires of the specified
type, size, brand, construction (bias,
bias-belted, radial or run-flat) , and
tread pattern on all four wheels.
Failure to do so may result in a
circumference difference between
tires on the front and rear axles
which will cause excessive tire wear
and may damage the transmission,
transfer case and differential gears.
Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the rear wheels on the vehicle could lead to
mechanical damage.
For additional information regarding tires, refer
