2010 NISSAN ALTIMA tire size

●If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat
belts may retract slowly. Wipe the shoulder
belt guide with a clean, dry cloth.
● Periodically check to see that the seat
belt and the metal components, such as
buckles, tongues, retractors, flexible wires
and anchors work properly. If loose parts,
deterioration, cuts or other damage on the
webbing is found, the entire seat belt as-
sembly should be replaced. Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available from
many other sources, including doctors, teachers,
government traffic safety offices, and community
organizations. Every child is different, so be sure
to learn the best way to transport your child.
There are three basic types of child restraint
systems:
● Rear-facing child restraint
● Forward-facing child restraint
● Booster seat
The proper restraint depends on the child’s size.
Generally, infants up to about 1 year and less
than 20 lbs (9 kg) should be placed in rear-facing
child restraints. Forward-facing child restraints
are available for children who outgrow rear-
facing child restraints and are at least 1 year old.
Booster seats are used to help position a vehicle
lap/shoulder belt on a child who can no longer
use a forward-facing child restraint.

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label, located in the
driver’s door opening.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all 4 tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. 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. 3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra windshield–washer fluid to refill the
reservoir tank.

Tire and loading information label
1Seating capacity: The maximum num-
ber of occupants that can be seated
in the vehicle.
2Vehicle load limit: See “Vehicle load-
ing information” in the “Technical and
consumer information” section.
3Original tire size: The size of the tires
originally installed on the vehicle at
the factory.
4Cold tire pressure: Inflate the tires to
this pressure when the tires are cold.
Tires are considered COLD after the
vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6
km) at moderate speeds. The recom-
mended cold tire inflation is set by the
manufacturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the
vehicle’s GVWR.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify 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 information) .
2. Three-digit number (215): This num- ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3. Two-digit number (65): This number, 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 number
is the wheel or rim diameter in inches.
6. Two- or three-digit number (95): This number is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause 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 “Depart- ment Of Transportation”. The symbol
can be placed above, below or to the
left 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. Three-digit code: Date of Manufac- ture.
6. Four numbers represent the week and year the tire was built. For ex-
ample, the numbers 3103 means the
31st week of 2003. If these numbers
are missing, then look on the other
sidewall of the tire.
3Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in the
tire, which include steel, nylon, polyester,
and others.
4Maximum permissible inflation pres-
sure
This number is the greatest amount of air
pressure that should be put in the tire. Do
not exceed the maximum permissible in-
flation pressure.
5Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory in-
stalled tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”) .

●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 because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
● Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact a NISSAN
dealer.
● For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
