2003 NISSAN FRONTIER tires

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.

DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
Treadwear
Treadwear grade is a comparative rating based
on tire wear rate when tested under controlled
conditions on specified government test courses.
For example, a tire graded 150 would wear one
and a half (1-1/2) times as well on the govern-
ment course as a tire graded 100. However,
relative tire performance depends on actual driv-
ing conditions, and may vary significantly due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests and does not in-
clude acceleration, cornering, hydroplan-
ing or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest) , B, and
C. They represent a tire’s resistance to heat
build-up, and its ability to dissipate heat when
tested under controlled conditions on a specified
indoor laboratory test wheel. Sustained high tem-
perature can cause tire material to degenerate,
reducing tire life. Excessive temperatures can
lead to sudden tire failure. Grade C corresponds
to a performance level which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades A and B rep-
resent higher levels of performance on laboratory
test wheels than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, ei-
ther separately or in combination, can
cause heat build-up and possible tire
failure.
