2002 NISSAN SENTRA flat tire

checked when tires are COLD. Tires are
considered COLD after the vehicle has
been parked for three or more hours, or
driven less than 1 mile (1.6 km) at moderate
speeds. COLD tire pressures are shown on
the tire placard affixed to the driver's side
rear door pillar.
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 heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed rated tires. Driving
faster than 85 MPH (140 km/h) may
result in tire failure, loss of control
and possible injury.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
TYPES OF TIRES
WARNING
cWhen changing or replacing tires, be
sure all four tires are of the same
type (i.e., summer, all season or
snow) and construction. An autho-
rized NISSAN dealer may be able to
help you with information about tire
type, size, speed rating and availabil-
ity. Replacement tires may have a
lower speed rating than the factory
equipped tires, and may not matchthe potential maximum vehicle speed.
Never exceed the maximum speed rat-
ing of the tire.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Informa-
tion Booklet (US) or ``Tire Safety In-
formation'' in the Warranty and Road-
side Assistance Information booklet
(Canada).
All Season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year round, including snowy and icy road
conditions. All Season tires are identified by
``ALL SEASON'' and/or ``M&S'' on the tire
sidewall. Snow tires have better snow trac-
tion 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 is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating
``M&S'' on the tire sidewall.
8-44Maintenance and do-it-yourself
ZX

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 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 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.
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.
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.
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 of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ªSº 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 be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire. Do not use tire
chains on dry roads.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
CHANGING WHEELS AND TIRES
Tire rotation
Tire should be rotated every 7,500 miles
(12,000 km).
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
As soon as possible, tighten the wheel
nuts to the specified torque with a torque
wrench.

Maintenance and do-it-yourself8-45
ZX

The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation interval.
WARNING
cAfter rotating the tires, check and
adjust the tire pressure.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
cDo not include the spare tire in the
tire rotation.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Tire wear and damage
WARNING
c
Tires should be periodically inspected
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.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire(s) should
be replaced.cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an authorized
NISSAN dealer.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Replacing 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'' of 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, construc-
tion(bias, bias-belted, radial), or tread
patterns can adversely affect the ride,

cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional 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 pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (lo-
cated on the driver's side rear door
pillar).
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' 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. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
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 prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloadedtrailer 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 pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.

DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Quality grades can be found where appli-
cable 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 govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly 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 repre-
sent a tire's ability to stop on wet pavement
as measured under controlled conditions,
on specified government test surfaces of
asphalt and concrete. A tire marked C mayhave poor traction performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering, hydro-
planing, or peak traction characteris-
tics.
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 condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature 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 represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in combi-
nation, can cause heat build-up and
possible tire failure.
