2009 NISSAN ARMADA wheel size

When the low tire pressure warning light illumi-
nates, you should stop and adjust the tire pres-
sure to the recommended COLD tire pressure
shown on the Tire and Loading Information label.
The low tire pressure warning light does not
automatically turn off when the tire pressure is
adjusted. After the tire is inflated to the recom-
mended pressure, the vehicle must be driven at
speeds above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure warning
light. Use a tire pressure gauge to check the tire
pressure.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
placed in the ON position. The light will remain on
after the 1 minute. Have the system checked by a
NISSAN dealer.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section.WARNING
cIf the light does not illuminate with the
ignition switch in the ON position, have
the vehicle checked by a NISSAN dealer
as soon as possible.
cIf the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light OFF.
If the light still comes on while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire, re-
place it with a spare tire as soon as
possible.cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
CAUTION
cThe TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
cIf the vehicle is being driven at speeds
of less than 16 MPH (25 km/h), the
TPMS may not operate correctly.
cBe sure to install the specified size of
tires to the 4 wheels correctly.

CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo not push or tow your vehicle to start
the engine.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than passen-
ger cars to make them capable of performing in a
variety of on-pavement and off-road applications.
This gives them a higher center of gravity than
ordinary cars. An advantage of higher ground
clearance is a better view of the road, allowing
you to anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form satisfactorily under off-road conditions. If at
all possible, avoid sharp turns at high speeds. As
with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
Be sure to read the driving safety precautions
later in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,

cTo avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack and evenly
distribute the load. Secure heavy loads
in the cargo area as far forward and as
low as possible. Do not equip the ve-
hicle with tires larger than specified in
this manual. This could cause your ve-
hicle to roll over.
cDo not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
cBefore operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
cLower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
cDo not drive beyond the performance
capability of the tires, even with 4WD
engaged.cFor 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
cDo not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
cAccelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.cIf at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your NISSAN four-wheel drive vehicle
has a higher center of gravity than a
two-wheel drive vehicle. The vehicle is
not designed for cornering at the same
speeds as conventional two-wheel
drive vehicles. Failure to operate this
vehicle correctly could result in loss of
control and/or a rollover accident.
cAlways use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
cBe sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
cWhenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See “Periodic mainte-
nance” in the “NISSAN Service and
Maintenance Guide.”

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
cThe Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
cTire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.– When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see
“Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h).
When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
This action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. 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 surfaces may be
poorer than that of non-studded snow tires.3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
cA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
cA sturdy, flat board to be placed under the
jack to give it firm support.
cA shovel to dig the vehicle out of snowdrifts.
cExtra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
cWet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.cWhatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.
cAllow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
cAllow greater following distances on
slippery roads.
cWatch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a patch of
ice is seen ahead, brake before reach-
ing it. Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
cDo not use the cruise control on slip-
pery roads.
cSnow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of a
recall.
s1Tire size (example: P215/65R15 95H)
1. P: The9P9indicates the tire is de-
signed for passenger vehicles (not all
tires have this information) .
2. Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.4. R: The9R9stands for radial.
5. Two-digit number (15): This number
is the wheel or rim diameter in inches.
6. Two- or three-digit number (95): 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 be-
cause it is not required by law.
7. H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.

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 out-
ward 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
cWhen 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.
cReplacement 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.
cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the low tire pres-
sure warning system.
cFor additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
All season tires
NISSAN specifies All Season tires on some mod-
els to provide good performance all year, includ-
ing snowy and icy road conditions. 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 tires
NISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced 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 rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.

Generally, snow tires have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never ex-
ceed 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, 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 surfaces may be
poorer than that of non-studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P275/60R20 size tires. Installation of
the tire chains/cables on P275/60R20 size
tires will cause damage to the vehicle. If
you plan to use tire chains/cables, you
should install P265/70R18 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 yourvehicle 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 de-
signed to meet the 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 recommended 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 addi-
tion, 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.
Do not use tire chains on dry roads. Driving with
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
See “Flat tire” in the “In case of emer-
gency” section in this manual for tire re-
placing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
