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 deformations on the bead
portion. However, if you use a
lever-type tire 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 ad-
versely affect the ride, braking,
VDC system, handling, ground
clearance, body-to-tire clearance, tire chain clearance, speed-
ometer calibration, headlight
aim and bumper height. Some of
these effects may lead to acci-
dents 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 dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics, 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.

. 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. It is recommended you
contact a GT-R certified NISSAN
dealer as soon as possible for tire
replacement and/or system re-
setting. .
Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. Contact a GT-R certified
NISSAN dealer for ID registration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed 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 re-

garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) 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 differ-
ence between tires on the front
and rear axles which will cause
excessive tire wear and may da-
mage the transmission, transfer
case and differential gears.
Wheel balanceUnbalanced 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 per-
formed 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 Informa-
tion” (US) or “Tire Safety Information” (Canada) in the Warranty Information
Booklet.

JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.
Make sure the parking brake is
securely applied and the trans-
mission is shifted into the
position.
. Never change tires when the ve-
hicle 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 assis-
tance.
Blocking wheelsPlace suitable blocks
at both the front
and back of the wheel diagonally oppo-
site the flat tire to prevent the vehicle
from moving when it is jacked up.

ENGINE OUTPUT
High altitudeTo protect the engine, engine output is
controlled so that it does not increase at
altitude of approximately 3,281 ft (1,000
m) or higher.Engine output according to the
coolant temperatureThe engine output is controlled at a low
level when the engine coolant tempera-
ture is lower than approximately 158°F
(70°C) or higher than 230°F (110°C). This is
not a malfunction. If the temperature is lower than approxi-
mately 158°F (70°C), drive the vehicle until
it reaches normal operating temperature.
If the temperature is higher than 230°F
(110°C), perform cool-down driving proce-
dure. (
“Cool down” page GTR-14)
When the temperature of the engine
coolant is between 158°F (70°C) and
230°F (110°C), the engine output returns
to normal.
UNEVEN WEAR OF TIRESThe GT-R is equipped with high perfor-
mance, low profile, run-flat tires that are
optimized for performance and handling.
The life of these tires will be less than
those of tires installed on a typical vehicle,
and you are likely to experience uneven
tire wear and tire noise regardless of the
type of tire used.NOISES ARE HEARD WHILE DRIV-

Refer to the separate Multi Function
Display Owner’s Manual.
. The tire pressure sensor should be
reset anytime the wheels or tires are
removed or replaced.
. If the tire is removed in order to
replace the tire pressure sensor bat-
tery, it may not be possible to reuse
the removed tire from the wheel. To
replace the tire pressure sensor bat-
tery, it is recommended you contact a
GT-R certified NISSAN dealer.
WARNING
.If the low tire pressure warning
light illuminates while driving,
avoid sudden steering maneu-
vers or abrupt braking, reduce
vehicle speed, pull off the road
to a safe location and stop the
vehicle as soon as possible. Driv-
ing with under-inflated tires may
permanently damage the tires
and increase the likelihood of tire
failure. Serious vehicle damage
could occur and may lead to an
accident and could result in ser-
ious personal injury. Check the tire pressure for all four tires.
Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low
tire pressure warning light off. If
the light still illuminates while
driving after adjusting the tire
pressure, a tire may be flat
(
“Run-flat tires” page 6-4) or
the TPMS may be malfunctioning.
If no tire is flat and all tires are
properly inflated, have the vehicle
checked. It is recommended you
have the vehicle checked by a
GT-R certified NISSAN dealer.
. Although you can continue driv-
ing with a punctured run-flat tire,
remember that vehicle handling
stability is reduced, which could
lead to an accident and personal
injury. Also, driving a long dis-
tance at high speeds may da-
mage the tires.
. 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 conditions and other factors.
. When a wheel is replaced, the
TPMS will not function and the
low tire pressure warning light
will flash for approximately 1
minute. The light will remain on
after 1 minute. It is recommended
you contact your GT-R certified
NISSAN dealer as soon as possi-
ble for tire replacement and/or
system resetting.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction
of the tire pressure sensors.
NOTICE
.The TPMS may not function prop-
erly when the wheels are
equipped with tire chains or the
wheels are buried in snow.
. The TPMS may not function prop-
erly if the TPMS sensor is not
reset and when wheels/tires from

could affect the proper operation
of the TPMS.
. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction
of the tire pressure sensors.
NOTE:
. You can check the pressure of all
four tires on the touch screen dis-
play. See the separate Multi Func-
tion 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. It is recommended you
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.
However, NISSAN recommends re-
filling with nitrogen for maximum
tire performance.

NOTICE
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.TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires. When
the low tire pressure warning light is lit,
one or more of your tires is significantly
under-inflated. The system also displays
pressure of all tires on the touch screen
display by sending a signal from a sensor
that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure.

“Low tire pressure warning light”
page 2-30) (
“Tire Pressure Monitoring
System (TPMS)” page 5-4) (

page 6-3)
Tire inflation pressure
Check the tire pressure often and
always prior to long distance trips.
The recommended tire pressure
specifications are shown on the F.
M.V.S.S./C.M.V.S.S. label or the Tire
and Loading Information label (if so
equipped) under the “Cold Tire
Pressure” heading. The Tire and
Loading Information label is affixed
to the driver side door end. Tire
pressures should be checked reg-
ularly because:.
Most tires naturally lose air over
time.
.
Tires can lose air suddenly when
driven over potholes or other
objects or if the vehicle strikes
a curb while parking.
NOTE:
. You can check the pressure of all
four tires on the touch screen dis-
play. See the separate Multi Func-
tion 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. It is recommended you
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.
However, NISSAN recommends re-
filling with nitrogen for maximum
tire performance.
The tire pressures should be
checked when the tires are cold.
The 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.
Incorrect tire pressure, including
under inflation, may adversely
affect tire life and vehicle hand-
ling.
WARNING
.
Improperly inflated tires can
fail suddenly and cause an
accident.
.
The Gross Vehicle Weight
rating (GVWR) is located on

the F.M.V.S.S./C.M.V.S.S. cer-
tification label. The vehicle
weight capacity is indicated
on the Tire and Loading In-
formation label (if so
equipped). Do not load your
vehicle beyond this capacity.
Overloading your vehicle
may result in reduced tire
life, unsafe operating condi-
tions due to premature tire
failure, or unfavorable hand-
ling characteristics and
could also lead to a serious
accident. Loading beyond
the specified capacity may
also result in failure of other
vehicle components.
.
Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pres-
sure gauge to ensure that
the tire pressures are at the
specified level.
.
For additional information
regarding tires, refer to “Im-
portant Tire Safety Informa-tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.
NOTE:
.
Use only genuine GT-R tires and
road wheels.
The GT-R uses specially designed
run-flat tires and matching road
wheels. Use of these specially devel-
oped tires and wheels provides the
greatest potential for maximum
performance.
—Genuine GT-R tires and road
wheels help achieve maximum
cornering and braking perfor-
mance.
— Genuine GT-R tires and road
wheels help achieve maximum
tire durability during acceleration.
— Genuine GT-R tires and road
wheels help achieve maximum
handling capability during perfor-
mance driving.
— Genuine GT-R tires and road
wheels help provide road holding
in the event of decreasing tire
pressure and punctures. —
Genuine GT-R tires and road
wheels help prevent the decrease
of straight-running stability
caused by uneven tire wear due
to high rigidity wheels and wide
tires.
. 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 repla-
cement be performed 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 defor-
mations 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. It is recom-
mended you contact a GT-R certified
NISSAN dealer if the tires need to be
removed from the wheels.
