2012 NISSAN ARMADA wheel size

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 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 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.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
●The use of tires other than those recom-
mended 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, VDC system, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to acci-
dents and could result in serious per-
sonal injury.
● If your vehicle was originally equipped
with 4 tires that were the same size and
you are only replacing 2 of the 4 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 conditions and cause an acci-
dent and personal injury. ●
If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics, affect
the VDC system and/or interference
with the brake discs/drums. Such inter-
ference can lead to decreased braking
efficiency and/or early brake pad/shoe
wear. Refer to “Wheels and tires” in the
“Technical and consumer information”
section of this manual for wheel off-set
dimensions.
● When 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.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS. ●
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 with-
out warning.
● The use of retread tires is not
recommended.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial) , 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 will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.
Maintenance and do-it-yourself8-45

If excessive tire wear is found, it is recommended
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.
Contact a NISSAN dealer.
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 bal-
anced 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 Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Care of wheels
● Wash the wheels when washing the vehicle
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.

TOWING SAFETY
Trailer hitch
Your vehicle may be equipped with an optional
trailer tow package. The trailer tow package in-
cludes a receiver-type frame mounted hitch. This
hitch is rated for the maximum towing capacity of
this vehicle when the proper towing equipment is
used. Choose a proper ball mount and hitch ball
that is rated for the trailer to be towed. Genuine
NISSAN ball mounts and hitch balls are available
from your NISSAN dealer.
If your vehicle is not equipped with the optional
trailer tow package, check the towing capacity of
your bumper hitch or receiver-type frame
mounted hitch. Choose a proper hitch for your
vehicle and trailer. A genuine NISSAN trailer
hitch is available from your NISSAN dealer. Make
sure the trailer hitch is securely attached to the
vehicle to help avoid personal injury or property
damage due to sway caused by crosswinds,
rough road surfaces or passing trucks.
WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than the
weight rating of the hitch components.
Never exceed the weight rating of the
hitch components. Doing so can cause
serious personal injury or property
damage.
Hitch ball
Choose a hitch ball of the proper size and weight
rating for your trailer:● The required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on the top of the ball.
● Choose the proper class hitch ball based on
the trailer weight.
● The diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should
be no more than 1/16” smaller than the hole
in the ball mount.
● The threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount and
the ball mount is inserted into the hitch receiver.
Choose a proper class ball mount based on the
trailer weight. Additionally, the ball mount should
be chosen to keep the trailer tongue level with the
ground.
Weight carrying hitches
A weight carrying or “dead weight” ball mount is
one that is designed to carry the whole amount of
tongue weight and gross weight directly on the
ball mount and on the receiver.
Weight distribution hitch
This type of hitch is also called a “load-leveling” or
“equalizing” hitch. A set of bars attach to the ball
mount and to the trailer to distribute the tongue
weight (hitch weight) of your trailer. Many vehicles
can’t carry the full tongue weight of a given trailer,
and need some of the tongue weight transferred
through the frame and pushing down on the front
wheels. This gives stability to the tow vehicle.
A weight-distributing hitch system (Class IV) is
recommended if you plan to tow trailers with a
maximum weight over 5,000 lbs (2,268 kg) .
Check with the trailer and towing equipment
manufacturers to determine if they recommend
the use of a weight-distributing hitch system.
