q 1
Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
q 2
Vehicle load limit: See loading infor-
mation in the ªTechnical and con-
sumer informationº section. q 3
Original size: The size of the tires
originally installed on the vehicle at
the factory.
q 4
Cold tire pressure: Inflate the tires
to this pressure when the tires are
cold. Tires are considered COLD
after the vehicle has been parked for
3 or more hours, or driven less than
1 mile (1.6 km) at moderate speeds.
The recommended cold tire inflation
is set by the manufacturer to pro-
vide the best balance of tire wear,
vehicle handling, driveability, tire
noise, etc., up to the vehicle's
GVWR.

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 specifi-
cation 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 re-
lease air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires,
including the spare. (Refer to the

to place standardized information on
the sidewall of all tires. This informa-
tion identifies and describes the funda-
mental characteristics of the tire and
also provides the tire identification
number (TIN) for safety standard certifi-
cation. The TIN can be used to identify
the tire in case of a recall. q 1
Tire size (example: P215/65R15 95H)
1. P: The ªPº indicates the tire is de-
signed for passenger vehicles. (Not
all tires have this information).
2. Three-digit number (215): This
number gives the width in millime-
ters of the tire from sidewall edge to
sidewall edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives the
tire's ratio of height to width. SDI1575

4. R: The ªRº stands for radial.
5. Two-digit number (15): This number
is the wheel or rim diameter in
inches.
6. Two- or three-digit number (95): 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 be-
cause it is not required by law.
7. H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.
q 2
TIN (Tire Identification Number) for a
new tire (example: DOT XX XX XXX
XXXX)
1. DOT: Abbreviation for the ªDepart-
ment of Transportationº. The
symbol can be placed above,
below or to the left or right of
the Tire Identification Number.
2. Two-digit code: Manufacturer's iden-
tification mark
3. Two-digit code: Tire size 4. Three-digit code: Tire type code (Op-
tional)
5. Three-digit code: Date of Manufac-
ture
6. Four numbers represent the week
and year the tire was built. For ex-
ample, the numbers 3103 mean the
31st week of 2003. If these numbers
are missing, then look on the other
sidewall of the tire.
q 3
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 in-
clude steel, nylon, polyester, and
others.
q 4
Maximum permissible inflation pres-
sure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the
maximum permissible inflation pres-
sure. SDI1607

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 a TEMPORARY
USE ONLY spare tire.
Do not use the chains on dry roads. Driv-
ing with chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.
CHANGING WHEELS AND TIRES Tire rotation (Sedan)
INFINITI recommends rotating the tires
every 7,500 miles (12,000 km).
See ªFlat tireº in the ª6. In case of
emergencyº section for tire replacing
procedures.
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 z m) The wheel nuts must be kept tightened
to specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation in-
terval.
WARNING O After rotating the tires, check and
adjust the tire pressure.
O Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) (also in cases of a
flat tire, etc.).
O Do not include the T-type spare
tire or any other small size spare
tire in the tire rotation.
O For additional information re-
garding tires, refer to ªImportant
Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada)
in the Warranty Information
Booklet.

rear tires and the direction of the wheel
rotation is fixed for each tire.
A pin is on the front brake rotor to pre-
vent the rear wheels from being in-
stalled in place of the front wheels. The
spare tire can be installed in place of
the front and rear wheels. When install-
ing the spare tire in the front wheel, the
hole in the spare tire wheel must be
aligned with the pin on the brake rotor.
WARNINGO Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) (also in cases of a
flat tire, etc.).
O For additional information re-
garding tires, refer to ªImportant

2. Location mark
Tire wear and damage
WARNINGO Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found, the
tire(s) should be replaced. O The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
O 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.
O Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an INFINITI
dealer.
O For additional information re-
garding tires, refer to ªImportant
Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada)
in the Warranty Information
Booklet.
Replacing wheels and tires When replacing a tire, use the same size,
speed rating and load carrying capacity
as originally equipped. See ªSpecifica- MDI0004C

O Do not use abrasive cleaners when
washing the wheels.
O Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
O INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
Spare tire (TEMPORARY USE ONLY
spare tire (T-type)) Observe the following precautions if the
T-type spare tire must be used, otherwise
your vehicle could be damaged or in-
volved in an accident.
CAUTIONO The T-type spare tire should be used only
for an emergency. It should be replaced by
a standard tire at the first opportunity.
O Drive carefully while the T-type spare tire
is installed.
Avoid sharp turns and abrupt braking
while driving. O Periodically check the T-type spare tire
inflation pressure, and always keep it at
60 psi (420 kPa, 4.2 bar).
O With the T-type spare tire installed, do
not drive your vehicle at speeds faster
than 50 MPH (80 km/h).
O When driving on roads covered with
snow or ice, the T-type spare tire should
be used on the front wheel and the origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the rear
two original tires (Sedan).
O
Tire tread of the T-type spare tire will wear
at a faster rate than the original tire. Re-
place the T-type spare tire as soon as the
tread wear indicators appear.
O Do not use the T-type spare tire on other
vehicles.
O Do not use more than one T-type spare
tire at the same time.
O Do not tow a trailer while the T-type
spare tire is installed. CAUTION O Do not use tire chains on a T-type spare
tire. Tire chains will not fit properly on
the T-type spare tire and may cause
damage to the vehicle.
O Because the T-type spare tire is smaller
than the original tire, ground clearance
is reduced. To avoid damage to the ve-
hicle do not drive over obstacles. Also do
not drive the vehicle through an auto-
matic car wash since it may get caught.
