1998 NISSAN FRONTIER wheel size

cBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
cAlways drive with the floor mats in
place as the floor may become very
hot. Particular care should be taken
if you are barefoot.
cLower your speed when encounter-
ing strong crosswinds. With its
higher center of gravity, your
NISSAN is more affected by gusty
side winds. Slower speeds ensure
better vehicle control.
cDo not drive beyond the perfor-
mance of the tires even with 4WD.
cAccelerating quickly, steering or
braking may cause loss of control.
cInstall the same size of winter tires
on all four (four) wheels (such as
studless tires) or install tire chains
to the rear wheels when driving on
slippery roads (e.g., after a snow)
and drive carefully using 4WD.
cBe sure to check the brakes immedi-
ately after driving in mud or water asspecified in ``Wet brakes'' under the
heading ``Brake system,'' later in this
section.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
cWhenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. For
details, refer to ``Maintenance for off-
road driving'' in the ``Maintenance''
section of this manual.CAUTION
Always use tires of the same 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
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
CAUTION
ONLY use spare tires specified for each
four-wheel drive model.
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.

built-in diagnostic feature that tests the sys-
tem each time you start the engine and
move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you
may hear a ``clunk'' noise and/or feel a
pulsation in the brake pedal. This is normal
and is not an indication of any malfunction. If
the computer senses any malfunction, it
switches the anti-lock brake system off and
turns on the ABS brake warning light in the
dashboard. The brake system then operates
normally, but without anti-lock assistance.
If an abnormality occurs in the system, the
anti-lock function will cease but the ordinary
brakes will continue to operate normally. The
ABS brake warning light will then come on.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.
Using the System
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
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.
cWhen replacing tires, install the
specified size of tires on all four
wheels.
cWhen 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

Tire equipment
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use on all four
wheels of MUD & SNOW or ALL SEA-
SON tires. Please consult your NISSAN
dealer for the tire type, size, speed rating
and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit 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.
3. Tire chains may be used. Use of tire
chains may be prohibited according tolocation. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.Use only SAE
Class ``S'' chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility of whipping action damage to the
fenders or undercarriage. If possible,
avoid fully loading your vehicle when
using tire chains. In addition, drive at a
reduced speed, otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected. Never install tire chains on a
TEMPORARY USE ONLY spare tire. Do
not use tire chains on dry roads.
Special winter equipment
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-
move ice and snow from the windows
and wiper blades.2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
Driving on snow or ice
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow, or ice can be slick
and very hard to drive on. The ve-
hicle will have a lot less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.
cWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.
c
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
cAllow greater following distances on
slippery roads.

If you have a flat tire, see the ``In case of
emergency'' section of this manual.
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
cImproperly inflated tires can fail sud-
denly and cause an accident
c
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.
cBefore 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.
cDo 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
DI0047

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 in
snow and ice will be substantially reduced.
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'' 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 han-
dling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
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.
Four-wheel drive model
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
CAUTION
ONLY use spare tires specified for each
four-wheel drive model.
Tire chains
Use of tire chains may be prohibited accord-
ing 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 sug-
gestions.Use only SAE class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must besecured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or undercarriage. If possible, avoid fully
loading your vehicle when using tire chains.
In addition, drive at a reduced speed. Oth-
erwise, your vehicle may be damaged
and/or vehicle handling and performance
may be adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
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. When driv-
ing on clear paved roads, be sure to change
to 2WD.

cImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is nec-
essary to repair the TEMPORARY
USE ONLY spare tire, contact an
authorized 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
c
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.cIf 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.
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 warn-
ing.
cThe 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. Failure to do so may result in a
circumference difference between tireson 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.
CAUTION
ONLY use spare tires specified for each
four-wheel drive model.
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.
