1999 NISSAN FRONTIER tire pressure

During the first 1,000 miles (1,609 km),
follow these recommendations for the future
reliability and economy of your new vehicle.
Failure to follow these recommendations
may result in vehicle damage or shortened
engine life.
IDo not run the engine over 4,000 rpm.
IDo not drive over the following speed
limits:
two-wheel drive models:
55 MPH (88 km/h)
four-wheel drive models
(2H or 4H position):
55 MPH (88 km/h)
four-wheel drive models
(4L position):
30 MPH (48 km/h)
IDo not accelerate at full throttle in any
gear.
IAvoid quick starts.
IAvoid hard braking as much as possible.
IDo not tow a trailer for the first 500 miles
(805 km).IAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelera-
tor position.
IDrive at moderate speeds on the high-
way. Driving at high speeds lowers fuel
economy.
IAvoid unnecessary stopping and brak-
ing. Maintain a safe distance behind
other vehicles.
IUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
IAvoid unnecessary engine idling.IKeep your engine tuned up.
IFollow the recommended periodic main-
tenance schedule.
IKeep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and wastes fuel.
IKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
IAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
IWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
I
Use 4H or 4L position only when neces-
sary. Four-wheel drive operation lowers
fuel economy.

CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. A spare tire of the same size,
brand, construction and tread pattern
must also be used. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which will cause excessive tire wear
and may damage the transmission,
transfer case and differential gears.
If excessive tire wear is found, it is recom-
mended 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 an
authorized NISSAN dealer.
Snow tires
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
Tire inflation pressure
Periodically check the pressure in all tires,
including the spare, with a gauge. Adjust to
the specified pressure if necessary. Tire
pressures are shown on the tire placard
affixed to the glove box.
Tire chain
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains
in such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress. When driving on clear
paved roads, be sure to change to 2WD.

Using the system, 2WD Vehicles
(2 wheel rear ABS)
Depress the brake pedal and hold it down.
With the rear anti-lock brake system, the
front wheels can still lock. If this happens,
release the brake pedal slightly and then
reapply pressure.
WARNING
The anti-lock brake system is a sophis-
ticated device. But it cannot prevent
accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control under
some conditions, but remember that
the stopping distance on slippery sur-
faces 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 responsibility for
safety of self and others rests in the
hands of the driver.Tire type and condition may also affect
braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
``Tire placard'' in the ``Technical and
consumer information'' section.
Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it in the key hole.
Anti-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check anti-freeze (ethylene glycol base) to
assure proper winter protection. For details,
see ``Engine cooling system'' in the ``Do-it-
yourself'' section of this manual.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself''
section of this manual.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refill

Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (includ-
ing the spare). Tire pressure should be
checked when tires are COLD. COLD tire
pressures are shown on the tire placard
affixed to the inside of the glove box lid.
Incorrect tire pressure may adverselyaffect tire life and vehicle handling.
COLD pressure:
After vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km).
WARNING
IImproperly inflated tires can fail sud-
denly and cause an accident
I
The vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
IBefore taking a long trip, or when-
ever you have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
IDo not drive your vehicle over 85
MPH (137 km/h) unless it is equippedwith high capability tires. Driving
faster than 85 MPH (137 km/h) may
result in tire failure, loss of control
and possible injury.
Types of tires
WARNING
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. An authorized NISSAN
dealer may be able to help you with
information about tire type, size, speed
rating and availability. Replacement
tires may have a lower speed rating
than the factory equipped tires, and
may not match the potential maximum
vehicle speed. Never exceed the maxi-
mum speed rating of the tire.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified by ``ALL SEASON'' and/or ``M&S'' on
the tire sidewall. Snow tires have better

Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km) for 2WD ve-
hicles and every 3,750 miles (6,000 km) for
4WD vehicles.
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
Wheel nut tightening torque:
87 to 108 ft-lb (118 to 147 N×m)
WARNING
IAfter rotating the tires, adjust the tire
pressure.
IRetighten the wheel nuts after the
wheels have been run for the first
600 miles (1,000 km) (also in cases of
a flat tire, etc.).
IDo not include the TEMPORARY
USE ONLY spare tire in the tire rota-
tion.
Tire wear and damage
WARNING
ITires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If
excessive wear, cracks, bulging or
deep cuts are found, the tire should
be replaced.
IThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.

IImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is neces-
sary to repair the TEMPORARY USE
ONLY spare tire, contact an autho-
rized NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
I
The use of tires other than those
recommended 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, snow chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.IIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, poor 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.
IDo 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 warn-
ing.
IThe use of retread tires is not recom-
mended.
FOUR-WHEEL DRIVE
MODELS
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. A spare tire of same size,
brand, construction and tread pattern
must also be used.Failure to do so may result in a circum-
ference difference between tires on the
front and rear axles which will cause
excessive tire wear and may damage
the transmission, transfer case and dif-
ferential gears.
If excessive tire wear is found, it is recom-
mended 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 an
authorized NISSAN dealer.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
Care of wheels
IWash the wheels when washing the ve-
hicle to maintain their appearance.
Do-it-yourself
8-35
ZX

IClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
IDo not use abrasive cleaners when
washing the wheels.
IInspect wheel rims regularly for dents or
corrosion. This may cause loss of pres-
sure or damage the tire bead.
INISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire
Your vehicle may be equipped with a TEM-
PORARY USE ONLY spare tire.
To avoid property damage or personal injury
when using the TEMPORARY USE ONLY
spare tire, observe the following cautions:
WARNING
IThe spare tire should be used for
emergency use only. It should be
replaced by the standard tire at the
first opportunity to avoid possible
tire or differential damage.IDrive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
IPeriodically check spare tire infla-
tion pressure. Always keep the pres-
sure of the T135/70R16 spare tire at
60 psi (420 kPa, 4.2 bar). For the full
size spare tire pressure, check the
tire placecard located on the inside
of the glovebox lid.
IDo not drive the vehicle at speeds
faster than 50 MPH (80 km/h).
I
When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the front wheels and the original tire
used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
ITire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the TEMPORARY USE ONLY spare
tire as soon as the tread wear indi-
cators appear.IDo not use the TEMPORARY USE
ONLY spare tire on other vehicles.
IDo not use more than one TEMPO-
RARY USE ONLY spare tire at the
same time.
IDo not tow a trailer when the TEM-
PORARY USE ONLY T135/70R16
spare is installed.
CAUTION
I
The transfer control lever must
be in the 2H position to prevent the
transfer case and differential gears
from being damaged.
IDo not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire
chains will not fit properly on a TEM-
PORARY USE ONLY spare tire and
may cause damage to the vehicle.
I
Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not
drive the vehicle through an automatic
car wash since it might get caught.
