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-

ling stability. If necessary, contact a GT-R
certified NISSAN dealer for assistance.
Frequently check the tire pressure information
display on the monitor screen and adjust
pressure of each tire properly. See the separate
Multi Function Display Owner’s Manual.
It can be difficult to tell if a run-flat tire is under-
inflated or flat. Check the tire pressures as
described earlier in this section. If the tire
becomes under-inflated while driving, the low
tire pressure warning light will come on. If the
tire becomes flat while driving, the low tire
pressure warning light and the run-flat tire
warning display will come on.
Low tire pressure:
If the vehicle is being driven with low tire
pressure, the low tire pressure warning light will
illuminate.
Flat tire:
If the vehicle is being driven with one or more flat
tires, the run-flat tire warning display will appear
continuously on the vehicle information display
and a chime will sound for 10 seconds.
The chime will only sound at the first indication
of a flat tire and the run-flat tire warning display
will illuminate continuously. When the flat tire
warning is activated, have the system reset and
the tire checked and replaced if necessary by aGT-R certified NISSAN dealer. Even if the tire is
inflated to the specified COLD tire pressure, the
warning light will continue to illuminate until the
system is reset by a GT-R certified NISSAN
dealer.
If the low tire pressure and the run-flat tire
warning appears on the vehicle information
display:
.
Do not exceed 50 MPH (80 km/h).
. Increase your following distance to allow for
increased stopping distances.
. Avoid sudden maneuvers, hard cornering
and hard braking.
WARNING
. Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling sta-
bility is reduced, which could lead to
an accident and personal injury.
Also, driving a long distance at high
speeds may damage the tire.
. Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than 50 miles (80 km) with a
punctured run-flat tire. The actual
distance the vehicle can be driven on a flat tire depends on outside
temperature, vehicle load, road con-
ditions and other factors.
. Drive safely at reduced speeds.
Avoid hard cornering or braking,
which may cause you to lose control
of the vehicle.
NOTICE
.Never install tire chains on a punc-
tured run-flat tire, as this could
damage your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smal-
ler than normal.
. Do not enter an automated car wash
with a punctured run-flat tire.
. Have the punctured tire replaced by
a GT-R certified NISSAN dealer as
soon as possible, as the tire’s
performance capability is reduced.
Maintenance and do-it-yourself8-39

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.

2. Location mark
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

to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet.

JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.Make sure the parking brake is
securely applied and the transmis-
sion is shifted into the
&Pposition.
. Never change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.
. Never change tires if oncoming
traffic is close to your vehicle. Wait
for professional road assistance.
Blocking wheels
Place suitable blocks*1at both the front and
back of the wheel diagonally opposite the flat
tire to prevent the vehicle from moving when it is
jacked up.
WARNING
Be sure to block the wheel as the
vehicle may move and result in personal
injury.
Getting the tools
NOTE:
A jack, jack lever and rod are not equipped
as standard with this vehicle. These parts
are dealer options. Contact a GT-R certi-
fied NISSAN dealer about acquiring a jack,
jack lever and rod. You can store a jack,
jack lever and rod in the floor in front of
the passenger’s seat.

CAUTION
After using the tools, put them back in
their original places. An accident may
occur if you leave them in the car
unsecured.
Jacking up the vehicle and removing
the tire
WARNING
.Never get under the vehicle while it
is supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use the correct jack-up points.
Never use any other part of the
vehicle for jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the
jack.
. Do not start or run the engine while
vehicle is on the jack, as it may
cause the vehicle to move. This is
especially true for vehicles with limited slip differentials.
. Do not allow passengers to stay in
the vehicle while it is on the jack.
Carefully read the caution label attached
to the jack body and the following instruc-
tions.
Jack-up point
1. Place the jack directly under the jack-up point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
The jack should be used on level firm
ground.
