TIRE PRESSURE
Tire inflation pressureCheck the pressure of the tires (including the
spare) often and always prior to long distance
trips. The recommended tire pressure specifica-
tions are shown on the Tire and Loading Infor-
mation label under the “Recommended Cold
Tire Inflation Pressure” heading. The tire and
Loading Information label is affixed to the driver
side center pillar. Tire pressures should be
checked regularly because:

Most tires naturally lose air over time.

Tires can lose air suddenly when driven over
potholes or other objects or if the vehicle
strikes a curbwhile parking.
The tire pressures should be check when the
tires are cold. The 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.
Incorrect tire pressure, including under in-
flation, may adversely affect tire life and
vehicle handling.

WARNING

Improperly inflated tires can fail sud-
denly and cause an accident.

The vehicle weight capacity is indi-
cated on the Tire and Loading Infor-
mation label. Do not load your ve-
hicle beyond this capacity. Over-
loading your vehicle may result in
reduced tire life, unsafe operating
conditions due to premature tire mal-
functions, or unfavorable handling
characteristics and could also lead to
a serious accident. Loading beyond
the specified capacity may also result
in a malfunction of other vehicle
components.

Before taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.

Do not drive your vehicle over 85
MPH (137 km/h) unless it is equippedwith high-speed capability tires. Driv-
ing faster than 85 MPH (137 km/h)
may result in tire malfunction, loss of
control and possible injury.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Low tire pressure warning system
(if so equipped)The low tire pressure warning system monitors
the tire pressure of all tires (except the spare tire)
by sending a signal from a sensor that is installed
in each wheel. For more details, refer to “Low tire
pressure warning light” in the “2. Instruments
and controls” section, “Low tire pressure warn-
ing system” in the “5. Starting and driving”
section, and “Flat tire” in the “6. In case of
emergency” section. The low tire pressure warn-
ing system will activate only when the vehicle is
driven at speeds above 20 MPH (32 km/h).

Tire and loading information label
1Seating capacity: The maximum number of
occupants that can be seated in the vehicle.
2Vehicle load limit: See loading information in
the Technical and consumer information sec-
tion.
3Original tire size: The size of the tires origi-
nally installed on the vehicle at the factory.
4Recommended cold tire inflation 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
provide the best tire wear and vehicle han-
dling characteristics based on the vehicles

Checking the tire pressure1. 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, includ-
ing the spare. (Refer to the “Wheels and
tires” section.)
TIRE LABELINGFederal law requires tire manufacturers to place
standardized information 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 in case
of recall.
1Tire size (example: P215/60R16 94H)
1 P: The “P” indicates the tire is designed for
passenger vehicles.
2. Three-digit number (215): This number gives
the width in millimeters of the tire from side-
wall edge to sidewall edge.
(Not all tires have this information.)
3. Two-digit number (60): This number, known
as the aspect ratio, gives the tire’s ratio of
height to width.
4. R: The “R” stands for radial.
5. Two-digit number (16): This number 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: Speed Rating. The speed rating denotes
the speed at which a tire is designed to be
driven for extended periods of time. The
ratings range from 98 miles per hour (MPH)
to 186 MPH. (You may not find this informa-
tion on all tires because it is not required by
law.)
2TIN (Tire Identification Number) for new tire
(example: DOT XX XX XXX XXXX)
1. DOT: Abbreviation for the “Department of
Transportation”. The symbol can be
placed above, below 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-digit code: Date of Manufacture6. Four numbers represent the week and year
the tire was built. For example, the numbers
3103 means the 31st week of 2003.
3Tire 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.
4Maximum 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.
5Maximum 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.
6Term of “tubeless” or “tube type”
Indicates that the tire requires an inner tube
(“tube type”) or not (“tubeless”).
7The word “radial”

TYPES OF TIRES
CAUTION

When changing or replacing tires, be
sure all four tires are of the same
type (i.e., summer, all season or
snow) and construction. Your
NISSAN dealer 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.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information booklet.All season tiresNISSAN specifies all season tires on some
models to provide good performance for use allyear around, including snowy and icy road con-
ditions. All season tires are identified by ALL
SEASON and/or M&S on the tire sidewall. Snow
tires have better snow traction than all season
tires and may be more appropriate in some
areas.
Summer tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance in snow and ice will be
substantially reduced. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW or ALL SEASON tires on all four wheels.Snow tiresIf 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 on four wheel drivemodels, they must also be the same size, brand,
construction and tread pattern on all four
wheels.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW or ALL SEASON tire on all four wheels.
For additional traction on icy roads, studded tires
may be used. However, some provinces and
states 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 CHAINSUse of tire chains is prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions.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 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 recom-
mended by the tire chain manufacturer 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 perfor-
mance may be adversely affected.
Never install tire chains on TEMPORARY USE
ONLY spare tires.
Do not use tire chains on dry roads.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the vari-
ous mechanisms of the vehicle due to some
overstress. When driving on clear paved roads,
be sure to change to 2WD.
CHANGING WHEELS AND TIRES
Tire rotationNISSAN recommends that tires be rotated every
7,500 miles (12,000 km). However, the timing
for tire rotation may vary according to your
driving habits and road surface conditions.
See “Flat tire” in the “6. In case of emergency”
section for tire replacing procedures.
Wheel nut tightening torque:
98 ft-lb (133 N⋅m)The wheel nuts must be kept tightened to speci-
fication at all times. It is recommended that
wheel nuts be tightened to specification at each
tire rotation interval.
WARNING

After rotating the tires, adjust the tire
pressure.

Retighten the wheel nuts after the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).

Do not include small size spare tire in
the tire rotation.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information booklet.
