WARNING
. If the tires are replaced with
different sized tires, the predic-
tive course line may not be dis-

If any malfunction occurs in the AWD
system while the engine is running, the
warning light will come on.
The warning light may blink rapidly
(about twice per second) while trying to
free a stuck vehicle due to high AWD
clutch temperature. The driving mode
may change to two-wheel drive. If the
warning light blinks rapidly during opera-
tion, stop the vehicle with the engine
idling in a safe place immediately. Then if
the light goes off after a while, you can
continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn and winter
tires are not installed on the front or rear
wheels only.
If the warning light is blinking after the
above operation, it is recommended you
have your vehicle checked by a GT-R
certified NISSAN dealer as soon as possi-
ble.
If non-genuine GT-R tires are used, the
warning light may illuminate. (

TIGHT CORNER BRAKING PHE-
NOMENONIf the steering wheel is turned more than
half a turn when the vehicle is started
when it is cold, it may be harder to move
the vehicle forward and backward. This
phenomenon is known as the “tight
corner braking phenomenon”.
This phenomenon is unique to AWD
vehicles, and occurs due to a difference
in speeds between the front and rear
wheels while the vehicle is turning. This
does not indicate that there is a malfunc-
tion.
NOTE:
If the tight corner braking phenomenon
occurs, a slipping sound may be heard
from the tires, or a squeaking sound
may be heard from the drive system.Reducing tight corner braking
phenomenonThe tight corner braking phenomenon
can be reduced if the following three
conditions are met:
.Transmission setup switch is set to
Normal mode.
. Vehicle speed is low (less than ap-
proximately 6 MPH (10 km/h)). .
The steering wheel is turned more
than 1/2 turn.
TIRESThis vehicle is equipped with special tires.
When changing the tires, install the de-
signated special tires. Replacing tires as a
set of four with new ones is recom-
mended. 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.
NOTICE
If tires other than the designated
tires, tires with large differences in
wear or tires of different sizes are
installed, the AWD performance will
be degraded and the drive mechan-
ism may be damaged.
AWD SYSTEM CHARACTERISTICSThe AWD system automatically distri-
butes the optimal torque to the front
and rear wheels. This provides both the
superior turning performance of a rear
wheel drive vehicle and the traction of a
AWD vehicle.
Electronic control continuously distri-
butes torque to the front and rear wheels
in the range from 0:100 (rear-wheel drive
mode) to 50:50 (all-wheel drive mode) to
match the driving conditions and road
conditions. This allows the engine output
(torque) to be effectively transmitted to
the road surface.

installed tire.
The word “radial”
The word “radial” is shown, if the
tire has radial structure.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 sec-
tion, 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 informa-
tion about tire type, size, speed
rating and availability.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.All-season tiresNISSAN 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 tiresThe GT-R summer tires are made from a
specially formulated rubber to maximize
the vehicle’s performance capabilities.
Performance of summer tires is substan-
tially reduced when temperatures are less
than 32°F (0°C) so you must drive care-
fully. 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 tem-
peratures are less than 32°F (0°C).

ways use run-flat tires of the specified
size on all four wheels. Mixing tire sizes or
construction may reduce vehicle handling
stability. If necessary, contact a GT-R
certified NISSAN dealer for assistance.
Frequently check the tire pressure infor-
mation on the touch screen display and
adjust pressure of each tire properly. See
the separate Multi Function Display Own-
er’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 warn-
ing light will come on. If the tire becomes
flat while driving, the low tire pressure
warning light and the run-flat tire warn-
ing display will come on.
Low tire pressure:
NOTICE
.Never install tire chains on a
punctured run-flat tire, as this
could damage your vehicle.
. Avoid driving over any projection
or pothole, as the clearance be-
tween the vehicle and the ground
is smaller than normal.
. Do not enter an automated car
wash with a punctured run-flat
tire.
. It is recommended you have the
punctured tire replaced by a GT-R
certified NISSAN dealer as soon

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.

FRONT/REAR TIRE SIZE DISCRE-
PANCY WARNINGThis will appear if the diameter of the
front and the rear wheels are different.
