NISSAN XTERRA 2006 N50 / 2.G Owners Manual

If you have a flat tire, see the “In case of
emergency” section of this manual.
TIRE PRESSURE
Tire pressure monitoring system
This vehicle is equipped with the tire pressure
monitoring system. It monitors tire pressure of all
tires except the spare. When the low tire pres-
sure warning light is lit, one or more of your tires is
significantly underinflated.
The tire pressure monitoring system will activate
only when the vehicle is driven at speeds above
16 MPH (26 km/h) . Also, this system may not
detect a sudden drop in tire pressure (for ex-
ample a flat tire while driving) .
For more details, refer to “Low tire pressure warn-
ing light” in the “Instruments and controls” sec-
tion, ”Tire pressure information” in the “Display
screen, heater, air conditioner and audio sys-
tems” section, “Tire pressure monitoring system”
in the “Starting and driving” section, and “Flat
tire” in the “In case of emergency” section.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long dis-
tance trips. The recommended tire pres-
sure specifications are shown on the FM-VSS label or the Tire and Loading
Information label (if so equipped) under
the9Recommended Cold Tire Inflation
Pressure9heading. The Tire and Loading
Information label is affixed to the driver
side center pillar. Tire pressures should
be checked regularly because:
cMost tires naturally lose air over time.
cTires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curb while
parking.
The tire pressures should be checked
when the tires are cold. The 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.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
cImproperly inflated tires can fail
suddenly and cause an accident.
cThe Gross Maximum Weight rat-
ing is located on the FMVSS la-
bel. The vehicle weight capacity
is indicated on the Tire and Load-
ing Information label (if so
equipped) . Do not load your ve-
hicle beyond this capacity. Over-
loading your vehicle may result in
reduced tire life, unsafe operat-
ing conditions due to premature
tire failure, or unfavorable han-
dling characteristics and could
also lead to a serious accident.
Loading beyond the specified ca-
pacity may also result in failure of
other vehicle components.
cBefore taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.

Checking tire pressure
1. 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 side-
ways, or air will escape. If the hissing
of air escaping from the tire is heard
while checking the pressure, reposi-
tion the gauge to eliminate this leak-
age.3. Remove the gauge.
4. Read the tire pressure on the gauge
stem and compare to the specifica-
tion shown on the Tire Placard (if so
equipped) or the Tire and Loading
Information label (if so equipped) .
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 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.
2. Three-digit number: This number
gives the width in millimeters of the
tire from sidewall edge to sidewall
edge.
3. Two-digit number: 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: This number is the
wheel or rim diameter in inches.
6. Two- or three-digit number: 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. Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.

and year the tire was built. For ex-
ample, the numbers 3103 means the
31st week of 2003. If these numbers
are missing, then look on the other
sidewall of the tire.
s3Tire ply composition and materialThe number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in the
tire, which include steel, nylon, polyester,
and others.
s4Maximum permissible inflation pres-
sure
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.
s5Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried 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.
s6Term of ”tubeless” or ”tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”) .

Manufacturer or brand name is 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 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.
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
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.Class9S9chains 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.

Wheel nut tightening torque:
98 ft-lb (133 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
cAfter rotating the tires, check and
adjust the tire pressure.
cRetighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
cDo not include the spare tire in
the tire rotation.

Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced.cThe original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact a NISSAN
dealer.

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
cThe 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, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
cIf 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 and/or
interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to “Wheels and tires” in the “Techni-
cal and consumer information” section
of this manual for wheel off-set
dimensions.cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the low tire pressure
warning system will not function. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cDo not install a deformed wheel or tire
even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warning.
cThe use of retread tires is not
recommended.
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.
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.
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.
