2023 NISSAN FRONTIER wheel size

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
• While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshif ting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an
accident.
• If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces 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 ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
BRAKE SYSTEM
5-118Starting and driving

–When installing a spare tire, makesure that it is the proper size and
type as specified on the Tire and
Loading Information label. For addi-
tional information, see “Tire and
Loading Information label” (P. 10-14).
– For additional information, see
“Wheels and tires” (P. 8-32).
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric pumps,
hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature
that tests the system 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 does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov e3-6mph(5-10
km/h). The speed varies according to road
conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
Starting and driving5-119

• When the Idling Stop System is deacti-vated af ter the engine has been auto-
matically stopped by the Idling Stop Sys-
tem, the engine will immediately restart if
suitable conditions are present. The en-
gine will then be prevented from auto-
matically stopping during the same
journey.
NOTE:
•The Idling Stop System ON or OFF mes-
sage is displayed for a few seconds in
the vehicle information display when
the Idling Stop System OFF switch is
pushed. For additional information, see
“Idling Stop System Display ” (P. 5-131).
• The Idling Stop System resets to ON every time the ignition switch is
switched from the OFF position to the
ON position.
• It is best to disable the ISS system when towing a trailer. You can do this
by pushing the Idling Stop OFF switch.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob (if so equipped).
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-6).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P. 8-16).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-7).
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 of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing 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. For additional information, see “Tire chains” (P. 8-40).

TIRE LABELING
Federal law requires tire manufac-
turers to place standardized infor-
mation on the sidewall of all tires.
This information identifies and de-
scribes the fundamental character-
istics of the tire and also provides the
Tire Identification Number (TIN) for
safety standard certification. The TIN
can be used to identif y the tire in
case of a recall.
O1Tire size (example: P215/65R15
95H)
1. P: The “P” indicates the tire is de- signed for passenger vehicles (not
all tires have this information).
2. Three-digit number (215): This number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge. 3. Two-digit number (65): This num-
ber, known as the aspect ratio,
gives the tire's ratio of height to
width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This num- ber is the wheel or rim diameter in
inches.

O6Term of “tubeless” or “tube type”
Indicates whether the tire requires
an inner tube (“tube type”) or not
(“tubeless”).
O7The word “radial”
The word “radial” is shown if the tire
has radial structure.
O8Manufacturer or brand name
Manufacturer or brand name is

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 outward facing sidewall of an asymmetrical tire that has a particu-
lar side that must always face out-
ward when mounted on a vehicle.
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. A NISSAN dealer
may be able to help you with infor-
mation 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 maximum
speed rating of the tire.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the low
tire pressure warning system. •
Always use tires of the same type,
size, brand, construction 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 can cause the
Vehicle Dynamic Control (VDC) sys-
tem to malfunction resulting in per-
sonal injury or death, excessive tire
wear and may damage the transmis-
sion and differential gears.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. 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 appropri-
ate in some areas.
Do-it-yourself8-39

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced 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 rat-
ing 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 rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed 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, stud-
ded 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 ac-
cording 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 manufac-
turer's suggestions.
Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tire
size. 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 be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. 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 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.

WARNING
• Tires 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(s) should be
replaced.
• The original tires have built-in
tread wear indicators. When
the wear indicators are visible,
the tire(s) should be replaced.
• Tires degrade with age and
use. Have tires, including the
spare, over 6 years old checked
by a qualified technician be-
cause some tire damage may
not be obvious. Replace the
tires as necessary to prevent
tire failure and possible per-
sonal injury. •
Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. For ad-
ditional information, see “Wheels and tires”
(P. 10-10).
WARNING
• The use of tires other than those rec-
ommended 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, Vehicle Dy-
namic Control (VDC) system, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects
may lead to accidents and could re-
sult in serious personal injury.
• If your vehicle was originally
equipped with four tires that were
the same size and you are only re-
placing two of the four tires, install
the new tires on the rear axle. Placing
new tires on the front axle may cause
loss of vehicle control in some driving
conditions and cause an accident
and personal injury.
8-42Do-it-yourself

•If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, see
“Wheels and tires” (P. 10-10).
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS. •
The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
• When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a
NISSAN dealer for ID registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information 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
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. It is recom-
mended that you visit a NISSAN dealer for
this service.
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 balanced as required.
