Tire and Loading Information label
Seating capacity: The max-
imum number of occu-
pants that can be seated
in the vehicle.
Vehicle load limit: See “Ve-hicle loading information”
(P.10-19).
Original size: The size of
the tires originally installed
on the vehicle at the fac-
tory.
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 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 pres-
sure, 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 infor-
mation on the sidewall of all tires.
This information identifies and de-
scribes the fundamental character-
istics 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.

SDI1606Example
Tire size (example:
P215/60R16 94H)
1. P: The “P” indicates the tire isdesigned 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 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: Tire speed rating. You should not drive the vehicle faster than
the tire speed rating.
JVM0694XExample
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, below or to the left or
right of the Tire Identification
Number.
2. Two-digit code: Manufacturer’s identification mark
Do-it-yourself8-31

8-32Do-it-yourself
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 fab-
ric in the tire.
Tire manufacturers also
must indicate the materials
in the tire, which include
steel, nylon, polyester, and
others.
Maximum permissible infla-
tion pressure
This number is the greatest
amount of air pressure
that should be put in the
tire. Do not exceed the maximum permissible in-
flation pressure.
Maximum load rating
This number indicates the
maximum load in kilo-
grams 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 in-
stalled 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 struc-
ture.
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 sec-
tion, Intended Outboard Sidewall is
(1) the sidewall that contains a
whitewall, bears white lettering or
bears manufacturer, 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 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 construc-
tion. A 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 fac-
tory 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
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
All season tires
NISSAN specifies all season tires on some
models to provide good performance all
year, including snowy and icy road con-
ditions. 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
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire trac-
tion rating M&S on the tire sidewall.
If you plan to operate your vehicle in
snowy or icy conditions, NISSAN recom-
mends 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 max-
imum vehicle speed. Never exceed the
maximum speed rating of the tire.
If you install snow tires, they must be the
same brand, construction and tread pat-
tern on all four wheels, and the same
sizes as the original tires.
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 sur-
faces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be
installed on 19-inch size tires. Doing
so will cause damage to the vehicle.
If you plan to use tire chains/cables,
you should install 18-inch size tires
on your vehicle.
Use 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
the 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 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 com-
ponent required to accommodate the
Do-it-yourself8-33

8-34Do-it-yourself
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 re-
commended 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 load-
ing your vehicle when using tire chains. In
addition, drive at a reduced speed. Other-
wise, 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 tire chains on dry roads.
Driving with tire chains in such conditions
can cause damage to the various me-
chanisms of the vehicle due to some
overstress.CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated on this
vehicle because the front tires are
a different size than the rear tires.
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 installing the
spare tire in the front wheel, the
hole in the spare tire wheel must be
aligned with the pin on the brake
rotor.
WARNING
.Retighten the wheel nuts
when the vehicle has been
driven for 600 miles (1,000
km) (also in cases of a flat
tire, etc.).
. For additional information
regarding tires, refer to “Im-
portant Tire Safety Informa- tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.

SDI1663
Wear indicator
Wear indicator location
marks. The locations are
shown by “
”, “TWI”, etc.
depending on tire types.
Tire wear and damage
WARNING
. Tires should be periodically
inspected 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.
. 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 tech-
nician, because some tire
damage may not be ob-
vious. Replace the tires as
necessary to prevent tire
failure and possible perso-
nal injury.
. Improper service of the
spare tire may result in ser-
ious personal injury. If it is
necessary to repair the
spare tire, it is recom-
mended you visit a NISSAN
dealer for this service.
. For additional information
regarding tires, refer to “Im- portant Tire Safety Informa-
tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load
carrying capacity as originally equipped.
(See “Specifications” (P.10-9) for recom-
mended 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, con-
struction (bias, bias-belted or ra-
dial), or tread patterns can
adversely affect the ride, braking,
handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibra-
tion, headlight aim and bumper
height. Some of these effects
may lead to accidents and could
result in serious personal injury.
