Installing the spare tire
The T-type spare tire (if so equipped) is
designed for emergency use. (See specific
instructions under the heading “Wheels and
tires” (P.8-32).)
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and
tighten the wheel nuts finger tight.
Models equipped with different sized
tires in the front and rear:
When replacing a front tire, make sure
that the hole in the spare tire wheel is
aligned with the pin on the brake rotor.

3. With the wheel nut wrench, tighten
wheel nuts alternately and evenly in the
sequence illustrated (
,,,,) until
they are tight.
4. 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 illu-
strated. 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) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque:
80 ft-lb (108 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 side center
pillar.
5. Securely store the flat tire and jacking
equipment in the vehicle.
6. Place the spare tire cover (if so equipped)
and the trunk floor carpeting over the
damaged tire.
7. Close the trunk.
WARNING
.Always make sure that the spare tire
(if so equipped) and jacking equip-
ment are properly secured after use.
Such items can become dangerous
projectiles in an accident or sudden
stop..The T-type spare tire and small size
spare tire (if so equipped) are de-
signed for emergency use. See spe-
cific instructions under the heading
“Wheels and tires” (P.8-32).
REPAIRING A FLAT TIRE (for
models with emergency tire punc-
ture repair kit)
WARNING
.After using Emergency Tire Sealant
to repair a minor tire puncture, do not
drive the vehicle at speeds faster
than 50 MPH (80 km/h).
.Immediately after using the Emer-
gency Tire Sealant to repair a minor
tire puncture, take your vehicle to
inspect, and repair or replace the tire.
It is recommended you visit an
INFINITI retailer for this service. The
Emergency Tire Sealant cannot per-
manently seal a punctured tire. Con-
tinuing operation of the vehicle
without a permanent tire repair can
lead to a crash.
.INFINITI recommends using only

Checking the tire pressure
1. Remove the valve stem cap from
the 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.

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.
SDI1606
Example
Tire size (example: P215/60R16
94H)
1. P: The “P” indicates the tire is
designed for passenger vehicles.
(Not all tires have this informa-
tion.)
2. Three-digit number (215): This
number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3. Two-digit number (60): This num-
ber, known as the aspect ratio,
gives the tire’s ratio of height to

width.
4. R: The “R” stands for radial.
F: The “F” after “R” indicates Self-
Supporting type run-flat tire.
5. Two-digit number (16): This num-
ber is the wheel or rim diameter in
inches.
6. Two- or three-digit number (94):
This number is the tire’s load index.
It is a measurement of how much
weight each tire can support. You
may not find this information on all
tires because it is not required by
law.
7. H: Tire speed rating. You should
not drive the vehicle faster than
the tire speed rating.

Example
TIN (Tire Identification Number) for
a new tire (example: DOT XX XX XXX
XXXX)
1. DOT: Abbreviation for the “De-
partment of Transportation”. The
symbol can be placed above, be-
low or to the left or right of the
Tire Identification Number.
2. Two-digit code: Manufacturer’s
identification mark
3. Two-digit code: Tire size
4. Three-digit code: Tire type code
(Optional)5. Four numbers represent the week
and year the tire was built. For
example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing, then
look on the other sidewall of the
tire.
Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire.
Tire manufacturers also must indicate
the materials in the tire, which include
steel, nylon, polyester, and others.
Maximum permissible inflation
pressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum
permissible inflation pressure.
Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as
the factory installed tire.

Term of “tubeless” or “tube type”
Indicates whether the tire requires an
inner tube (“tube type”) or not (“tube-
less”).
The word “radial”
The word “radial” is shown, if the tire
has radial structure.
Manufacturer or brand name
Manufacturer or brand name is
shown.
Other tire-related terminology:
In addition to the many terms that are
defined throughout this section, In-
tended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears manu-
facturer, brand and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall of the tire, or (2) the outward
facing sidewall of an asymmetrical
tire that has a particular side that
must always face outward when
mounted on a vehicle.
TYPES OF TIRES
WARNING
.When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or
Snow) and construction. An INFINITI
retailer may be able to help you with
information about tire type, size,
speed rating and availability.
.Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle speed.
Never exceed the maximum speed
rating of the tire.
.Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
.For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-
ranty Information Booklet.
All season tires
INFINITI specifies all season tires on some
models to provide good performance allyear, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than All Season tires and may
be more appropriate in some areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is
substantially reduced in snow and ice. Sum-
mer tires do not have the tire traction rating
M&S on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, INFINITI recommends the
use of SNOW tires or ALL SEASON tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the

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.
Run-flat tires
Your vehicle is equipped with run-flat tires.
You can continue driving to a safe location
even if they are punctured. Always use run-
flat tires of the specified size on all four
wheels. Mixing tire sizes or construction may
reduce vehicle handling stability. If neces-
sary, contact an INFINITI retailer for assis-
tance.
Frequently check the tire pressure and adjust
pressure of each tire properly. The tire
pressure can be also checked in the vehicle
information display.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire pres-
sures as described earlier in this section. If
the tire becomes under-inflated while driv-
ing, the low tire pressure warning light will
illuminate. If the tire becomes flat while
driving, the low tire pressure warning lightand the “Flat Tire - Visit dealer” warning will
appear.
Low tire pressure:
If the vehicle is being driven with low tire
pressure, the low tire pressure warning light
will illuminate.
Flat tire:
If the vehicle is being driven with one or more
flat tires, the low tire pressure warning light
will illuminate continuously and a chime will
sound for 10 seconds. A “Flat Tire - Visit
dealer” warning also appears in the vehicle
information display.
The chime will only sound at the first
indication of a flat tire and the warning light
will illuminate continuously. When the flat
tire warning is activated, have the system
reset and the tire checked, and replaced if
necessary. It is recommended you visit an
INFINITI retailer for these services. Even if
the tire is inflated to the specified COLD tire
pressure, the warning light will continue to
illuminate until the system is reset.
If the low tire pressure warning light illumi-
nates continuously and the “Flat Tire - Visit
dealer” warning appears in the vehicle
information display:
.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 stabi-
lity 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 approximately 93 miles
(150 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 conditions and other factors.
.Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the
vehicle.
.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
