2015 NISSAN GT-R flat tire

8-32Maintenance and do-it-yourself
If you have a flat tire, see the following
section. (“Flat tire” page 6-3)
CAUTION
A GT-R certified NISSAN dealer should
perform a tire change. It will be neces-
sary to reset the tire pressure sensors.
To change the tires, contact a GT-R
certified NISSAN dealer.
Be sure to use the tires and wheels together as
a set that are designated �for use with this
vehicle.
�bhen tire replacement is required, replacing the
tires as a set o�f �four with new tires is
recommended. However, i�f a tire is punctured
or damaged, it may be possible to replace only
the damaged tire. Determining whether one tire
or a complete set o�f tires should be replaced is
based on a number o�f �factors including tire wear
and condition. Contact your GT-R certi�fied
NISSAN dealer. They can recommend i�f an
individual tire or a complete set should be
replaced.
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 o�f all tires. �bhen the low tire pressure
warning light is lit, one or more o�f your tires is
signi�ficantly under-in�flated. The system also
displays pressure o�f all tires on the multi �function
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 warn-
ing light” page 2-27) (“Tire Pressure
Monitoring System (TPMS)” page 5-4)
(
“Flat tire” page 6-3)
Tire inflation pressure
Check the tire pressure o�ften and always
prior to long distance trips. The recom-
mended tire pressure speci�fications are
shown on the F.M.V.S.S./C.M.V.S.S. label
or the Tire and Loading In�formation label (i�f
so equipped) under the “Cold Tire Pres-
sure” heading. The Tire and Loading
In�formation label is a�f�fixed to the driver
side door end. Tire pressures should be
checked regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly when driven
over potholes or other objects or i�f the
vehicle strikes a curb while parking.
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.
WHEELS AND TIRES

.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.
The tire pressures should be checked
when the tires are cold. The tires are
considered \fOLD a\bter the vehicle has
been parked \bor 3 or more hours, or driven
less than 1 mile (1.6 km) at moderate
speeds.
Incorrect tire pressure, including un-
der inflation, may adversely affect tire
life and vehicle handling.
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. certification la-
bel. The vehicle weight capacity
is indicated on the Tire and
Loading Information label (if so
equipped) . Do not load your vehicle beyond this capacity.
Overloading your vehicle may
result in reduced tire life, unsafe
operating conditions due to pre-
mature tire failure, or unfavor-
able handling characteristics
and could also lead to a serious
accident. Loading beyond the
specified capacity may also re-
sult in failure of other vehicle
components.
.Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
.For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
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 developed tires
and wheels provides the greatest po-
tential for maximum performance.
—Genuine GT-R tires and road wheels
help achieve maximum cornering
and braking performance.
— Genuine GT-R tires and road wheels

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on t�fe side-
wall of all tires. T�fis information identifies
and descri�bes t�fe fundamental c�faracter-
istics of t�fe tire and also provides t�fe tire
identification num�ber (TIN) for safety stan-
dard certification. T�fe TIN can �be used to
identify t�fe tire in case of a recall.
Example
*1Tire size (example: P215/60R16 94H)
1.
P: T�fe “P” indicates t�fe tire is designed
for passenger ve�ficles. (Not all tires
�fave t�fis information.)
2.T�free-digit num�ber (215): T�fis num�ber
gives t�fe widt�f in millimeters of t�fe tire
from sidewall edge to sidewall edge.
3.Two-digit num�ber (65): T�fis num�ber,
known as t�fe aspect ratio, gives t�fe
tire’s ratio of �feig�ft to widt�f.
4.R: T�fe “R” stands for radial.
F: T�fe “F” after “R” indicates Self-
Supporting type run-flat tire.
5.Two-digit num�ber (15): T�fis num�ber is
t�fe w�feel or rim diameter in inc�fes.
6.Two- or t�free-digit num�ber (95): T�fis
num�ber is t�fe tire’s load index. It is a
measurement of �fow muc�f weig�ft eac�f
tire can support. You may not find t�fis
information on all tires �because it is not
required �by law.
7.H: Tire speed rating. You s�fould not
drive t�fe ve�ficle faster t�fan t�fe tire

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 pro�fide good performance for use
all year around�b 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
�fehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F (08C) so you
must dri�fe carefully. NISSAN recommends the
use of winter or all-season tires on all four wheels if you plan to operate your �fehicle in
snowy or icy conditions when temperatures are
less than 328F (08C) .
WARNING
Never use summer tires when the
temperature is below
í48F(í208C) 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 �fehicle is equipped with run-flat tires. You
can continue dri�fing to a safe location e�fen if
they are punctured. Always use run-flat tires of
the specified size on all four wheels. Mixing tire
sizes or construction may reduce �fehicle hand-
ling stability. If necessary�b contact a GT-R
certified NISSAN dealer for assistance.
Frequently check the tire pressure information
on the multi function display 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 dri�fing�b the low
tire pressure warning light will come on. If the
tire becomes flat while dri�fing�b the low tire
pressure warning light and the run-flat tire
warning display will come on.
Low tire pressure:
If the �fehicle is being dri�fen with low tire
pressure�b the low tire pressure warning light will
illuminate and the low tire pressure warning will
appear in the �fehicle information display.
Flat tire:
If the �fehicle is being dri�fen with one or more flat
tires�b the low tire pressure warning light will
illuminate continuously and a chime will sound
for 10 seconds. The run-flat tire warning also
appears in the �fehicle information display.
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 acti�fated�b ha�fe the system reset and
the tire checked and replaced if necessary by a
GT-R certified NISSAN dealer. E�fen if the tire is
inflated to the specified COLD tire pressure�b 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

.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.
Tires for All-Wheel Drive (AWD)
I�f excessive tire wear is �found, it is recom-
mended that all �four tires be replaced with tires
o�f the speci�fied 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 certi�fied
NISSAN dealer.
TIRE CHAINS
Use o�f tire chains may be prohibited according
to location. Check the local laws be�fore instal-
ling tire chains. When installing tire chains, make
sure they are o�f proper size �for the tires on your
vehicle and are installed according to the chain
manu�facturer 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 o�f 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 manu�facturer to ensure a tight �fit. Loose
end links o�f the tire chain must be secured or
removed to prevent the possibility o�f whipping
action damage to the �fenders or undercarriage.
I�f 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 per�formance
may be adversely a�f�fected.
