Checking the tire pressure
1. Remove the valve stem cap fromthe tire.
2. Press the pressure gauge squarely onto the valve stem. Do not press
too hard or force the valve stem
sideways, or air will escape. If the
hissing sound of air escaping from
the tire is heard while checking the
pressure, reposition the gauge to
eliminate this leakage.
3. Remove the gauge. 4. Read the tire pressure on the
gauge stem and compare it to the
specification shown on the Tire
and Loading Information label.
5. Add air to the tire as needed. If too much air is added, press the core of
the valve stem briefly with the tip
of the gauge stem to release
pressure. Recheck the pressure
and add or release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.
8. Check the pressure when driving the vehicle at speeds of 100 mph
(160 km/h) or higher where it is
legal to do so.
WARNING
.Driving at high speeds, 100
mph (160 km/h) or higher sus-
tained where it is legal to do so,
can cause tires to have exces-
sive heat build up, which may
result in a tire failure causing loss of control, crash, injuries or
even death. Some high-speed
rated tires require inflation
pressure adjustment for high-
speed operation. When speed
limits and road conditions allow
vehicle driving at high speeds,
make sure tires are rated to
support high speed operation,
tires are in optimal conditions
and pressure is adjusted to
correct cold inflation pressure
for high speed operation.
. Tires require adjustment to the
inflation pressure when driving
the vehicle at speeds of 100
mph (160 km/h) or higher
where it is legal to do so. See
recommended tire inflation
chart for correct operating
pressure.
. After vehicle high speed opera-
tion has ended, readjust the tire
pressure to the recommended
cold inflation pressure. (See
“Checking the tire pressure”

(P.8-30).)

TIRE LABELING
Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.
Do-it-yourself8-31

same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires. Skid and
traction capabilities of studded snow tires,
on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions.Use only SAE Class S chains. Class
“S” chains are used on vehicles with re-
stricted 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 of 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 manufac-
turer to ensure a tight fit. Loose end links of the tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on the full-size
temporary use only spare tire (if so
equipped).
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires at the specified interval shown
in the maintenance schedule. (See the
“Maintenance and schedules” section.
For tire replacing procedures, see
“Flat tire” (P.6-3).)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Do-it-yourself8-35

8-36Do-it-yourself
Wheel nut tightening torque:98 ft-lb (133 N·m)
The wheel nuts must be kept tigh-
tened to the specification at all times.
It is recommended that wheel nuts be
tightened to the specification at each
tire rotation interval.
WARNING
. After rotating the tires, check
and adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. Do not include the full-size
temporary use only spare tire
(if so equipped) in the tire
rotation.

Tire wear and damage
WARNING
.
Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.
. The original tires have built-in

tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-8) for recommended types
and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial), or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects may
lead to accidents and could result in
serious personal injury.
. For Two-Wheel Drive (2WD) models,
if your vehicle was originally
equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
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 and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) for wheel off-set dimensions.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or 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 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
. The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
. When replacing the TPMS sensor, the
ID registration may be required. It is

recommended you visit an INFINITI
retailer for ID registration.
. Do not use a valve stem cap that is
not specified by INFINITI. The valve
stem cap may become stuck.
. Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of pres-
sure.
. Do not install a damaged or deformed
wheel or tire even if it has been
repaired. Such wheels or tires could
have structural damage and could fail
without warning.
. The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-
ranty Information Booklet.Four-Wheel Drive (4WD) models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), 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 damage the trans-
mission, transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
you visit an INFINITI retailer for this service.
Wheel balance
Unbalanced wheels may affect vehicle hand-
ling 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 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 INFINITI Warranty Information Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire
Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEM-
PORARY USE ONLY), the TPMS will not
function.
Spare tire (FULL-SIZE TEMPORARY USE
ONLY spare tire):
Observe the following precautions if the full-
size temporary use only spare tire must be
used, otherwise your vehicle could be da-
maged or involved in an accident.
WARNING
.
The full-size temporary use only
spare tire should be used for emer-
gency use. It should be replaced with

the standard tire at the first oppor-
tunity to avoid possible tire or differ-
ential damage
. Drive carefully while the spare tire is
installed. Avoid sharp turns and
abrupt braking while driving. The
vehicle driving performance may be
affected when driving on wet or
snow covered roads.
. When the spare tire is installed, the
following systems may not work
correctly.
— Tire Pressure Monitoring System (TPMS)
— Vehicle Dynamic Control (VDC) System
. Periodically check spare tire inflation
pressure. Always keep the spare tire
inflated to the pressure specification
shown on the Tire and Loading
Information label. For Tire and Load-
ing Information label location, see
“Tire and Loading Information label”
in the index of this manual.
. With the spare tire installed do not
drive your vehicle at speeds faster
than 70 MPH (112 km/h).
. When driving on roads covered with
snow or ice, the spare tire should be
used on the front wheels and original tire used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire
at the same time.
CAUTION
Do not use tire chains on the spare tire.
Tire chains will not fit properly and may
cause damage to the vehicle.
