shown.
Other Tire-related Terminology
In addition to the many terms that
are defined throughout this section,
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 particu-
lar side that must always face out-
ward when mounted on a vehicle.
TYPES OF TIRES
WARNING
∙ When changing or replacing tires, be sure all four tires are of the same type
(i.e., 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 origi- nally specified by NISSAN could affect
the proper operation of the low tire
pressure warning system.
8-36Do-it-yourself

∙ Always use tires of the same type,size, brand, construction and tread
pattern on all four wheels. Failure to
do so may result in a circumference
difference between tires on the front
and rear axles which can cause the
Vehicle Dynamic Control (VDC) system
to malfunction resulting in personal
injury or death, excessive tire wear
and may damage the transmission
and differential gears.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
All-Wheel Drive (AWD) models
CAUTION
∙ ONLY use spare tires specified for the AWD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and corrected as necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year, 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 appropri-
ate 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 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 tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you donot, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings 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 size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, stud-
ded 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 surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
CAUTION
Only certain SAE class “S” tire chains can
be used on this vehicle. Using the wrong
Class “S” chains on this vehicle will
cause damage to the vehicle. If you plan
to use tire chains/cables, you should
use a tire chain that meets the mini-
mum clearances for your vehicle.
Do-it-yourself8-37

Use of tire chains may be prohibited ac-
cording 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 manufac-
turer’s suggestions. Use a tire chain that is
designed to provide the specified space
A
between the installed tire chain1and
where the tire meets the rim
2as shown
on the chart. NOTE:
Tire chains are not permitted for use
with 19 in wheels.
Wheel size
Minimum space
required
16 in .7 in (17 mm)
17 in .2 in (4 mm)
A tire chain that provides the specified
amount of space will provide the neces-
sary clearance between the tire and the
closest vehicle suspension or body com-
ponent. The minimum clearances are de-
termined using the factory-equipped tires.
Other types may damage your vehicle. Use
chain tensioners when recommended 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
front wheels and not on the rear 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 rotation
NISSAN recommends rotating the
tires every 5,000 miles (8,000 km) for
vehicles equipped with the PR25DD
engine and 7,500 miles (12,000 km)
for vehicles equipped with the
KR20DDET engine.
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
of this manual.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque:
83 f t-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times.
It is recommended that wheel nuts
be tightened to specification at
each tire rotation interval.
WARNING
∙ Af ter rotating the tires, check and adjust the tire pressure.
∙ Retighten the wheel nuts when the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
∙ Do not include the spare tire in the tire rotation. ∙ For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.WDI0258

Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
∙ 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. ∙ The original tires have built-in
tread wear indicators. When the
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 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 per-
sonal injury. If it is necessary to
repair the spare tire, it is recom-
mended that you visit a NISSAN
dealer for this service.
∙ For additional information re- garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. For ad-
ditional information, refer to “Wheels and
tires” in the “Technical and consumer infor-
mation” section of this manual.
WARNING
∙ The use of tires other than those rec-
ommended 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, Vehicle Dynamic
Control (VDC) system, ground clear-
ance, body-to-tire clearance, tire
chain clearance, speedometer cali-
bration, headlight aim and bumper
height. Some of these effects may
lead to accidents and could result in
serious personal injury.
WDI0259
8-40Do-it-yourself

∙ If your vehicle was originallyequipped with four tires that were the
same size and you are only replacing
two of the four tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and per-
sonal injury.
∙ If the wheels are changed for any rea- son, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section of
this manual. ∙ When replacing a wheel without the
TPMS, such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for this service.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ The TPMS sensor may be damaged if it is not handled correctly. Be careful
when handling the TPMS sensor.
∙ When replacing the TPMS sensor, the ID registration may be required. It is
recommended that you visit a NISSAN
dealer for ID registration.
∙ Do not use a valve stem cap that is not specified by NISSAN. The valve stem
cap may become stuck.
∙
Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and cause
a malfunction or loss of pressure.
∙ Do not install a damaged or deformed wheel or tire even if it has been re-
paired. Such wheels or tires could
have structural damage and could fail
without warning.
∙ The use of retread tires is not recommended.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
∙ For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Do-it-yourself8-41

Care of wheels
∙ Wash the wheels when washing the ve-hicle to maintain their appearance.
∙ Clean the inner side of the wheels when the wheel is changed or the underside
of the vehicle is washed.
∙ Do not use abrasive cleaners when washing the wheels.
∙ Inspect wheel rims regularly for dents or corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead.
∙ NISSAN recommends waxing the road wheels to protect against road salt in
areas where it is used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be
damaged or involved in an accident:
WARNING
∙ The spare tire should be used foremergency use only. It should be re-
placed with the standard tire at the
first opportunity to avoid possible tire
or differential damage.
∙ Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
∙ Periodically check spare tire inflation pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 420 kPa, 4.2 bar (60 psi).
∙ With the TEMPORARY USE ONLY spare tire installed do not drive the 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
rear wheels and the original tire used
on the front wheels (drive wheels). ∙ 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.
∙ Do not tow a trailer when the TEMPO- RARY USE ONLY spare tire is installed.
CAUTION
∙ Do not use tire chains on a TEMPO-RARY 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.
