2003 NISSAN FRONTIER tire pressure

cThe original tires have built-in tread
wear indicators. When the wear indica-
tors are visible, the tire(s) should be
replaced.
cImproper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, con-
tact a NISSAN dealer.
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.
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/tire size” 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 “Wheel/tire size” 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, the low tire pressure warn-
ing system will not function. Contact
your NISSAN dealer as soon as pos-
sible for tire replacement and/or sys-
tem resetting (for models with the low
tire pressure warning system) .
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.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 .
Care of wheels
cWash the wheels when washing the vehicle to
maintain their appearance.
cClean the inner side of the wheels when the
wheel is changed or the underside of the ve-
hicle is washed.
cDo not use abrasive cleaners when washing
the wheels.
cInspect wheel rims regularly for dents or cor-
rosion. Such damage may cause loss of pres-
sure or poor seal at the tire bead.
cNISSAN 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)
Your vehicle may be equipped with a TEMPO-
RARY SPARE USE ONLY spare tire.Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used,
Otherwise, your vehicle could be damaged or
involved in an accident:
WARNING
cThe spare tire should be used for emer-
gency use only. It should be replaced
with the standard tire at the first oppor-
tunity to avoid possible tire or differen-
tial damage.
cDrive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
cPeriodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 60 psi (420 kPa, 4.2 bar) .
cWith the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle at
speeds faster than 50 MPH (80 km/h) .

When the truck is used to carry a slide-in camper,
the total cargo load of the truck consists of the
camper manufacturer’s weight figure, plus:
cthe weight of installed additional camper
equipment not included in the camper manu-
facturer’s weight figure,
cthe weight of camper cargo,
cand the weight of occupants in the camper.
The total cargo load should not exceed the
truck’s pay load weight rating and the camper’s
center of gravity should fall within the truck’s
recommended center of gravity location zone
when installed.
WARNING
Overloading or improper loading can ad-
versely affect vehicle handling, braking
and performance and may lead to
accidents.
PAYLOAD WEIGHT CAPACITY
The payload weight capacity shown on following
charts indicate the maximum total weight of pas-
sengers, optional equipment (air conditioning,
trailer hitch, etc) and cargo that your vehicle is
designed to carry.
Before driving a loaded vehicle, confirm that you
do not exceed the Gross Vehicle Weight Rating
(GVWR) or the Gross Axle Weight Rating
(GAWR) for your vehicle. See ’’Vehicle Loading
Information’’ earlier in this section for details.
Also check tires for proper inflation pressures.
See the tire placard.

TOWING SAFETY
Trailer hitch
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.
CAUTION
cSpecial hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine NISSAN hitches for pickup trucks
and sport utility vehicles are available
at a NISSAN dealer.
cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
cDo not use axle-mounted hitches.
cDo not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.cTo reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
hitch and/or receiver when not in use.
cAfter the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
cRegularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard.
cTrailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturer’s
specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. Safety chains should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chains to permit turning
corners.
Trailer lights
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer.
Trailer brakes
If your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level posi-
tion when a loaded and/or unloaded trailer is
hitched. Do not drive the vehicle if it has an
abnormal nose-up or nose-down condition;
check for improper tongue load, overload,
worn suspension or other possible causes of
either condition.
cAlways secure items in the trailer to prevent
load shift while driving.
cBe certain your rear view mirrors conform to all
federal, state or local regulations. If not, install
any mirrors required for towing before driving
the vehicle.
