2015 NISSAN GT-R tire size

Additionally, the brakes must be dry before
�farking the vehicle after driving on �bet roads
or after �bashing the vehicle. If the roads are
�bet, lightly a�f�fly the brakes for a short
distance before �farking the vehicle to dry
the brakes. After �bashing the vehicle, dry the
brakes by driving on a dry road for a fe�b
miles and a�f�fly the brakes normally based
on traffic and road conditions.
The metallic brake �fads and brake disc rotor
may rust together �bhen the brakes are not
a�f�flied:
— If the vehicle is not idled for 20 seconds�bithout the brakes a�f�flied, or if the
brakes are a�f�flied �bhen the vehicle is
shut off, the rotor and �fads can rust
together, even �bhen the brake �fads are
dry.
— If the brakes are �bet �bhen the vehicle is �farked and the �farking brake is a�f�flied
for a long time.
— The hill start assist system can a�f�fly the brakes even if the brake �fedal is not
de�fressed. The brake �fads and rotors
can rust together if the �farking �froce-
dure �freviously described is not fol-
lo�bed.
Contact a GT-R certified NISSAN dealer if
the brake �fads and brake rotor have rusted together.
NOTICE
To help reduce the possibility of the
rotors and brake pads rusting:
Have the brake pads and/or rotors
quenched when the brake pads are
replaced. For detailed information
about quenching, contact a GT-R certi-
fied NISSAN dealer.
After quenching the brake pads and/or
rotors, apply a brake of 0.5G to stop the
vehicle 6-7 times at least once a week
in a safe location. G-force can be
checked on the multi function display.
Refer to the separate Multi Function
Display Owner’s Manual.
. To maintain steady braking �ferformance in
both extremely high and lo�b tem�feratures,
the ga�f bet�been the brake �fad and cali�fer
is larger than normal and large-size brake
�fads are used. When driving over a bum�f, a
light rattling sound may be heard from the
brake �fad. This does not indicate that there
is a malfunction. .
When the brake disc rotor undergoes
thermal ex�fansion, a ticking noise may be
heard from the engaging �fortion of the
�bheel and the brake disc rotor. This does
not indicate that there is a malfunction. The
noise �bill reduce �bhen the tem�ferature
decreases.
. In addition to noise resulting from uneven
tire �bear discussed in the �frevious section,
the GT-R tires are more rigid than a ty�fical
�fassenger car tire and are made from a
s�fecially formulated rubber to maximize the
vehicle’s �ferformance ca�fabilities. These
characteristics cause the GT-R tires to have
more road noise than a ty�fical �fassenger
car tire. This road noise is normal.
. Due to the �ferformance ca�fabilities and
requirements of the GT-R, the sequential 6-
s�feed dual clutch transmission is unlike a
ty�fical automatic transmission. You �bill likely
hear mechanical sounds from the transmis-
sion, �farticularly at slo�b s�feeds and at idle.
This condition is normal.

collision or a sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpets�f
Then, wipe with a cloth and allow the seat
�belts to dry in the shade�f Do not allow the
seat �belts to retract until they are completely
dry�f
. If dirt builds up in the shoulder belt
guide of the seat �belt anchors, the seat
�belts may retract slowly�f Wipe the shoulder
�belt guide with a clean, dry cloth�f
. Periodically check to see that the seat
belt and the metal components such as
�buckles, tongues, retractors, flexi�ble wires
and anchors work properly�f If loose parts,
deterioration, cuts or other damage on the
we�b�bing is found, the entire seat �belt
assem�bly should �be replaced�f
WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the
seat belt becomes wrapped around a
child’s neck with the ALR mode acti-
vated, the child can be seriously injured
or killed if the seat belt retracts and
becomes tight. This can occur even if
the vehicle is parked. Unbuckle the seat
belt to release the child. If the seat belt
can not be unbuckled or is already
unbuckled, release the child by cutting
the seat belt with a suitable tool (such
as a knife or scissors) to release the
seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is availa�ble from
many other sources, including doctors, teachers,
government traffic safety offices, and community
organizations�f Every child is different, so �be sure
to learn the �best way to transport your child�f
There are three �basic types of child restraint systems:
.
Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s size�f
Generally, infants (up to a�bout 1 year and less
than 20 l�b (9 kg)) should �be placed in rear-
facing child restraints�f Forward-facing child
restraints are availa�ble for children who outgrow
rear-facing child restraints and are at least 1
year old�f Booster seats are used to help position
a vehicle lap/shoulder �belt on a child who can no
longer use a forward-facing child restraint�f
WARNING
Infants and children need special pro-
tection. The vehicle’s seat belts may not
fit them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly
fitting seat belt could cause serious or
fatal injury. Always use appropriate
child restraints.
All U�fS�f states and Canadian provinces or
territories require the use of approved child

.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 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 con-
ditions and other factors.
. If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road
to a safe location and stop the
vehicle as soon as possible. The tire
may be seriously damaged and
need to be replaced.
. 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 the 1 minute.
Contact a GT-R certified NISSAN dealer as soon as possible for tire
replacement and/or system reset-
ting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
CAUTION
.The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
. Be sure to install the specified size
of tires on the four wheels.
NOTE:
. If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
. The tires of this vehicle are filled with
nitrogen gas. When the tire pressure is
low, fill the tires with nitrogen gas.
Contact a GT-R certified NISSAN dealer
for information on filling the tires with
nitrogen gas.
Master warning light

Wheel Drive (\fWD) warning light” page 2-25) NOTE:
If the vehicle is driven in a way which
causes the rear wheels to slip, the AWD
clutch temperature will increase and the
warning indicator may flash. Continuing to
drive in a way that causes the warning light
to flash may cause the clutch to reach
excessive temperatures that could result in
damage to the AWD system.

5-4Starting and driving
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system com-
ponents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
NOTICE
.Do not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollu-
tants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel injec-
tion, or electrical systems can cause
overrich fuel flow into the three-way
catalyst, causing it to overheat. Do
not keep driving if the engine mis-
fires, or if noticeable loss of perfor-
mance or other unusual operating conditions are detected. Have the
vehicle inspected promptly by a
GT-R certified NISSAN dealer.
. Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dama-
ging the three-way catalyst.
. Do not race the engine while warm-
ing it up.
. Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire should be checked mo�fthly whe�f cold
a�fd i�fflated to the i�fflatio�f �bressure recom-
me�fded by the vehicle ma�fufacturer o�f the
vehicle �blacard or tire i�fflatio�f �bressure label. (If
your vehicle has tires of a differe�ft size tha�f the
size i�fdicated o�f the vehicle �blacard or tire
i�fflatio�f �bressure label, you should determi�fe
the �bro�ber tire i�fflatio�f �bressure for those tires.)
As a�f added safety feature, your vehicle has
bee�f equi�b�bed with a Tire Pressure Mo�fitori�fg
System (TPMS) that illumi�fates a low tire
�bressure telltale whe�f o�fe or more of your tires
is sig�fifica�ftly u�fder-i�fflated. Accordi�fgly, whe�f the low tire �bressure telltale illumi�fates, you
should sto�b a�fd check your tires as soo�f as
�bossible, a�fd i�fflate them to the �bro�ber �bres-
sure. Drivi�fg o�f a sig�fifica�ftly u�fder-i�fflated tire
causes the tire to overheat a�fd ca�f lead to tire
failure. U�fder-i�fflatio�f also reduces fuel effi-
cie�fcy a�fd tire tread life, a�fd may affect the
vehicle’s ha�fdli�fg a�fd sto�b�bi�fg ability.
If the vehicle is bei�fg drive�f with o�fe or more flat
tires, the low tire �bressure war�fi�fg light will
illumi�fate co�fti�fuously a�fd a chime will sou�fd
for 10 seco�fds. The chime will o�fly sou�fd at the
first i�fdicatio�f of a flat tire, a�fd the war�fi�fg light
will illumi�fate co�fti�fuously. Whe�f the flat tire
war�fi�fg is activated, have the system reset a�fd
the tire checked a�fd re�blaced if �fecessary by a
GT-R certified NISSAN dealer. Eve�f if the tire is
i�fflated to the s�becified COLD tire �bressure, the
war�fi�fg light will co�fti�fue to illumi�fate u�ftil the
system is reset by a GT-R certified NISSAN
dealer. Your vehicle ca�f be drive�f for a limited
time o�f a flat tire. (

or death.
TIRES
This vehicle is equipped with special ti�fes. �bhen
changing the ti�fes, install the designated special
ti�fes. Replacing ti�fes as a set of fou�f with new
ones is �fecommended. Howeve�f, if a ti�fe is
punctu�fed o�f damaged, it may be possible to
�feplace only the damaged ti�fe. Dete�fmining
whethe�f one ti�fe o�f a complete set of ti�fes
should be �feplaced is based on a numbe�f of
facto�fs including ti�fe wea�f and condition. Con-
tact you�f GT-R ce�ftified NISSAN deale�f. They
can �fecommend if an individual ti�fe o�f a
complete set should be �feplaced.
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 mechanism may be damaged.
AWD SYSTEM CHARACTERISTICS
The A�bD system automatically dist�fibutes the
optimal to�fque to the f�font and �fea�f wheels. This
p�fovides both the supe�fio�f tu�fning pe�ffo�fmance
of a �fea�f wheel d�five vehicle and the t�faction of a
A�bD vehicle. Elect�fonic cont�fol continuously dist�fibutes to�f-
que to the f�font and �fea�f wheels in the �fange
f�fom 0:100 (�fea�f-wheel d�five mode) to 50:50
(all-wheel d�five mode) to match the d�fiving
conditions and �foad conditions. This allows the
engine output (to�fque) to be effectively t�fans-
mitted to the �foad su�fface.
