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 vehicle’s 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 specifica-tion 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. Re-
check 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.

Example
TIRE LABELINGFederal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental character-
istics of the tire and also provides the tire
identification number (TIN) for safety stan-
dard certification. The TIN can be used to
identify the tire in case of a recall.

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 construction. 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 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 ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in the
Warranty Information Booklet.All season tiresNISSAN specifies all season tires on some
Maintenance and do-it-yourself

models to provide good performance all year,
including snowy and icy road conditions. 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 appro-
priate in some areas.Summer tiresNISSAN 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 traction rating M&S on the tire
sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, NISSAN recommends the use of
SNOW tires 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, they must be the same
brand, construction and tread pattern 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 cap-
abilities of studded snow tires, on wet or dry
surfaces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled 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 instal-
ling 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 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 re-
commended 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 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 mechanisms of the vehicle due to
some overstress.

CHANGING WHEELS AND TIRES
Tire rotationTires 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 re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.

2. Wear indicator location markTire wear and damage
WARNING
.
Tires should be periodically in-
spected for wear, cracking, bul-
ging 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. Whenwear 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 technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
.
Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, contact a
NISSAN dealer.
.
For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See “SPECIFICA-
TIONS” in the “9. Technical and consumer
information” section for recommended types
and sizes of tires and wheels.)

the first opportunity to avoid possi-
ble tire or differential damage.
. Drive carefully while the TEMPOR-
ARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
. Periodically check spare tire infla-
tion pressure. Always keep the
pressure of the TEMPORARY USE
ONLY spare tire at 60 psi (420 kPa,
4.2 bar) . Always keep the pressure
of the full size spare tire (if so
equipped) at the recommended
pressure for standard tires, as in-
dicated on the Tire and Loading
Information label. For Tire and
Loading Information label location,
see “Tire and Loading Information
label” in the index of this manual.
. With the TEMPORARY USE ONLY
spare tire installed do not drive your
vehicle at speeds faster than 50
MPH (80 km/h) .
. When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the front wheels and original tire
used on the rear wheels (drive wheels) . Use tire chains only on the
two rear original tires.
. Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire
at the same time.
CAUTION
.Do not use tire chains on a TEM-
PORARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
. Because the TEMPORARY USE
ONLY spare tire is smaller than the
original tire, ground clearance is
reduced. To avoid damage to the
vehicle, do not drive over obstacles.
Also do not drive the vehicle
through an automatic car wash
since it may get caught.
EMERGENCY TIRE PUNCTURE RE-
PAIR KIT (if so equipped)The emergency tire puncture repair kit (Emer-
gency Tire Sealant) is supplied with the vehicle
instead of a spare tire. It can be used to
temporarily repair minor tire punctures.
If possible, have the vehicle towed to a facility
that can repair or replace the flat tire. Using the
emergency tire puncture repair kit may cause a
malfunction of the tire pressure sensor and
cause the low tire pressure warning light to
illuminate.
See “FLAT TIRE” in the “6. In case of
emergency” section for more details.
