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 checked 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 capacity weight is indi-
cated on the Tire and Loading Infor-
mation label. Do not load your ve-
hicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire mal-
function, 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 equipped
with high-speed rated tires. Drivingfaster than 85 MPH (137 km/h) may
result in tire failure, 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 displays
the tire pressure of all tires (except the spare tire)
on the trip computer by sending a signal from a
sensor that is installed in each wheel. For more
details, refer to “Trip computer” and “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. If the tire pressure dis-
played on the trip computer is lower than the
COLD tire pressure shown on the Tire and
Loading Information label, check the pressure of
all four tires and adjust them to the COLD tire
pressure. The low tire pressure warning 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 “9. Technical and consumer information”
section.
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 balance of tire wear, vehicle
handling, driveability, tire noise, etc., up to the
vehicles GVWR.

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.
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.
1Tire size (example: P215/60R16 94H)
P: The “P” indicates the tire is designed for
passenger vehicles. (Not all tires have this
information.)
Three-digit number (215): This number gives
the width in millimeters of the tire from side-
wall edge to sidewall edge.
1st two-digit number (60): This number,
known as the aspect ratio, gives the tire’s
ratio of height to width.
R: The “R” stands for radial.
2nd two-digit number (16): This number is
the wheel or rim diameter in inches.3rd two- or three-digit number (94): This
number is the tire’s load index. It is a mea-
surement of how much weight each tire can
support. (You may not find this information on
all tires because it is not required by law.)
H: Tire Speed Rating. The speed rating de-
notes the speed at which a tire is designed to
be driven for extended periods of time. The
ratings range from 98 MPH (miles per hour)
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)
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.
1st two-digit code: Manufacturer’s identifica-
tion mark
2nd two-digit code: Tire size
3rd three-digit code: Tire type code (Op-
tional)
4th three-digit code: Date of Manufacture
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”
The word “radial” is shown, if the tire has a
radial structure.
8Manufacturer or Brand name
Manufacturer or Brand name is shown.
Other tire-related terminologyIn addition to the many terms that are definedthroughout this section, Intended 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 sidewall of the tire, or (2) the outward
racing 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 (for example, summer, all sea-
son 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 all
year round, including snowy and icy road condi-
tions. 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 operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires 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 may be 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 chainmanufacturer’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
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.

Never install tire chains on a T-type
spare tire.

Do not use the chains on dry roads.

Tire chains must be installed only on the
rear wheels and not on the front wheels.
CHANGING WHEELS AND TIRES
Tire rotationTires cannot be rotated in this vehicle, as front
tires are different size from rear tires and the
direction of wheel rotation is fixed in each tire.
A pin is on the front brake rotor to prevent the
rear wheels from being installed 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.

Tire wear and damage
WARNING

Tires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If ex-
cessive wear, cracks, bulging, or
deep cuts are found, the tire should
be replaced.

The original tires have a built-in tread
wear indicator. When the wearindicator is visible, the tire should be
replaced.

Improper service for a spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact your NISSAN dealer.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. See “Specifications” in the “9. Tech-
nical and consumer information” section for rec-
ommended 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, construction(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 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 offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.

When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire
