2019 NISSAN ALTIMA Owner´s Manual

If the tires are used at speeds above
100 mph (162 km/h) where it is legal
to do so (on a race track for ex-
ample), the cold tire inflation pres-
sure must be increased. For addi-
tional information, refer to “Checking
tire pressure” in this section.
Set the tire pressure to the normal
cold tire inflation pressure when the
vehicle speed or load is reduced.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.WARNING
∙
Improperly inflated tires can fail
suddenly and cause an accident.
∙ The Gross Vehicle Weight Rat- ing (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label.
Do not load your vehicle beyond
this capacity. Overloading your
vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire fail-
ure, or unfavorable handling
characteristics and could also
lead to a serious accident. Load-
ing beyond the specified capac-
ity may also result in failure of
other vehicle components.
∙
Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.
∙ Increase the cold tire inflation pressure as indicated in "Check-
ing tire pressure" in this section
when using the tires specified
by NISSAN above 100 mph
(162 km/h) where it is legal to do
so (on a race track for example).
Failure to increase the cold tire
inflation pressure may result in
tire failure, loss of control and
possible injury. Af ter such use,
readjust tire pressure.
∙ For additional information re- garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

Checking tire pressure
1. Remove the valve stem cap fromthe tire.
2. Press the pressure gauge squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage. 3. Remove the gauge.
4. Read the tire pressure on the
gauge stem and compare to the
specification shown on the Tire
and Loading Information label.
5. Add air to the tire as needed. If too much air is added, press the
core of the valve stem briefly
with the tip of the gauge stem to
release pressure. Recheck the
pressure and add or release air
as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.

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.
1Tire size (example: P215/65R15
95H)
1. P: The “P” indicates the tire is de- signed for passenger vehicles
(not all tires have this informa-
tion).
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.

8-34Do-it-yourself

6. Two- or three-digit number (95):This number is the tire’s load in-
dex. It is a measurement of how
much weight each tire can sup-
port. You may not find this infor-
mation on all tires because it is
not required by law.
7. H: Tire speed rating. You should not drive the vehicle faster than
the tire speed rating.
2TIN (Tire Identification Number)
for a new tire (example: DOT XX XX
XXX XXXX)
1. DOT: Abbreviation for the “De- partment Of Transportation”.
The symbol can be placed
above, below or to the lef t or
right of the Tire Identification
Number.
2. Two-digit code: Manufacturer’s identification mark. 3. Two-digit code: Tire size.
4. Three-digit code: Tire type code
(Optional).
5. Four numbers represent the week and year the tire was built.
For example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing then
look on the other sidewall of the
tire.

Do-it-yourself8-35

3Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which include
steel, nylon, polyester and others.
4Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure.
5Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When re-
placing the tires on the vehicle, always
use a tire that has the same load rat-
ing as the factory installed tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires
an inner tube (“tube type”) or not
(“tubeless”).
7The word “radial”
The word “radial” is shown if the tire
has radial structure.
8Manufacturer or brand name
Manufacturer or brand name is
shown.
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 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 maximum
speed rating of the tire.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the low tire
pressure warning system.
8-36Do-it-yourself

∙ 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) system
to malfunction resulting in personal
injury or death, excessive tire wear
and may damage the transmission
and differential gears.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
All-Wheel Drive (AWD) models
CAUTION
∙ ONLY use spare tires specified for the AWD model.
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.
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.
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 donot, 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
CAUTION
Only certain SAE class “S” tire chains can
be used on this vehicle. Using the wrong
Class “S” chains on this vehicle will
cause damage to the vehicle. If you plan
to use tire chains/cables, you should
use a tire chain that meets the mini-
mum clearances for your vehicle.
Do-it-yourself8-37

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 a tire chain that is
designed to provide the specified space
A
between the installed tire chain1and
where the tire meets the rim
2as shown
on the chart. NOTE:
Tire chains are not permitted for use
with 19 in wheels.
Wheel size
Minimum space
required
16 in .7 in (17 mm)
17 in .2 in (4 mm)
A tire chain that provides the specified
amount of space will provide the neces-
sary clearance between the tire and the
closest vehicle suspension or body com-
ponent. The minimum clearances are de-
termined using the factory-equipped tires.
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
front wheels and not on the rear wheels. Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.
