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 which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics, 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. (
“Wheels
and tires” page 9-9)
. 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. Con-
tact a GT-R certified NISSAN dealer
as soon as possible for tire replace-
ment and/or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not install a damaged or de-
formed 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 regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) 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 difference between
tires on the front and rear axles
which will cause excessive tire wear
and may damage the transmission,
transfer case and differential gears.
Wheel balance
Unbalanced 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 performed
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 Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet.

JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.Make sure the parking brake is
securely applied and the transmis-
sion is shifted into the
&Pposition.
. Never change tires when the vehicle
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 assistance.
Blocking wheels
Place suitable blocks*1at both the front and
back of the wheel diagonally opposite the flat
tire to prevent the vehicle from moving when it is
jacked up.
WARNING
Be sure to block the wheel as the
vehicle may move and result in personal
injury.
Getting the tools
NOTE:
A jack, jack lever and rod are not equipped
as standard with this vehicle. These parts
are dealer options. Contact a GT-R certi-
fied NISSAN dealer about acquiring a jack,
jack lever and rod. You can store a jack,
jack lever and rod in the floor in front of
the passenger’s seat.
Maintenance and do-it-yourself8-43

8-44Maintenance and do-it-yourself
CAUTION
After using the tools, put them back in
their original places. An accident may
occur if you leave them in the car
unsecured.
Jacking up the vehicle and removing
the tire
WARNING
.Never get under the vehicle while it
is supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use the correct jack-up points.
Never use any other part of the
vehicle for jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the
jack.
. Do not start or run the engine while
vehicle is on the jack, as it may
cause the vehicle to move. This is
especially true for vehicles with limited slip differentials.
. Do not allow passengers to stay in
the vehicle while it is on the jack.
Carefully read the caution label attached
to the jack body and the following instruc-
tions.
Jack-up point
1. Place the jack directly under the jack-up point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
The jack should be used on level firm
ground.

2. Fit the jack head into the recess*Aof the
jack-up point by turning the jackscrew
clockwise with your fingers.
3. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground.4. Carefully raise the vehicle until the tire clears the ground. To lift the vehicle, securely hold
the jack lever and rod with both hands as
shown above.
Maintenance and do-it-yourself8-45

8-46Maintenance and do-it-yourself
5. Remove the wheel nuts and then remove thewheel.
NOTE:
When putting a wheel on the ground,
put it down with the outer side of the
wheel facing up to prevent scratching
of the wheel surface.6. Clean any mud or dirt from the surfacebetween the brake disc rotor
*1and wheel
*2.
7. Tighten the wheel nuts by hand by turningthem clockwise until the tapered part
*Aof
each nut lightly contacts the seat part
*Bof
the wheel hole.
When replacing a front wheel, make sure the
hole in the wheel is aligned with the pin on
the brake disc rotor.

8. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the sequence
as illustrated (
*1,*2,*3,*4,*5) until
they are tight.
9. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence as illustrated. Lower the
vehicle completely.
WARNING
.Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the
wheel studs or nuts. This could
cause the nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) .
WARNING
If the road wheels are hot, allow them
to cool sufficiently before tightening
the wheel nuts. Otherwise, the wheel
nuts cannot be tightened to specifica-
tion. NOTE:
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 97 ft-lb (132 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD
pressure.
COLD pressure: After the vehicle has
been parked for three hours or more
or driven less than 1 mile (1.6 km) .
COLD tire pressures are shown on
the Tire and Loading Information
label affixed to the driver’s door
opening.
10. Securely store the jacking equipment in the vehicle.
