ground clearance NISSAN GT-R 2015 R35 Owners Manual

6-4In case of emergency
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.
. 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.
RUN-FLAT TIRES
Run-flat tires are those tires that can be used
te�fporarily if they are punctured. �b“Run-flat
tires” page 8-39)
Also, see the tire safety infor�fation in the
Warranty Infor�fation Booklet.
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 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.
. 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
your GT-R certified NISSAN dealer
as soon as possible, as the tire’s
performance capability is reduced.
If you have a flat tire and have to stop the
vehicle, follow the instructions below.
1. Safely �fove the vehicle off the road and away fro�f traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to the
&Pposition.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance person-
nel that you need assistance.

. Avoid sudden maneuvers, hard cornering
and hard braking.

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.

8-42Maintenance and do-it-yourself
wear 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 require�f, replacing
tires as a set o�b �bour with new tires is
recommen�fe�f. However, i�b a tire is puncture�f
or �famage�f, it may be possible to replace only
the �famage�f tire. Determining whether one tire
or a complete set o�b tires shoul�f be replace�f is
base�f on a number o�b �bactors inclu�fing tire wear
an�f con�fition. Contact your GT-R certi�bie�fNISSAN �fealer. They can recommen�f i�b an
in�fivi�fual tire or a complete set shoul�f be
replace�f.
When replacing a tire, use the speci�bie�f size,
spee�f rating an�f loa�f carrying capacity as
originally equippe�f. (
“Wheels an�f 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 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
