Checking tire pressure
1. Remove the valve stem cap fromthe tire.
2. Press the pressure gauge se- curely onto the valve stem. Do not
press too hard or force the valve
stem sideways, otherwise 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 it to
the specification shown on the
Tire and Loading Information
label.
5. Add air to the tire as necessary. If too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to re-
lease pressure. Recheck the pres-
sure and add or release air as
necessary.
6. Install the valve stem cap.
7. Check the pressure of all of the tires.

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: P215/60R16
94H)
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 (60): 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 (16): This num- ber is the wheel or rim diameter in
inches.
6. Two- or three-digit number (94): 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.

O2TIN (Tire Identification Number)
for a new tire (example: DOT XX XX
XXX XXXX)
1. DOT: Abbreviation for the “Depart- ment of Transportation”. The sym-
bol can be placed above, below or
to the lef t or right of the Tire Iden-
tification 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.
O3Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire.
Tire manufacturers also must indi-
cate the materials in the tire, which
include steel, nylon, polyester, and
others.
O4Maximum 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.
O5Maximum load rating
This number indicates the maxi-
mum load in kilograms and pounds
that can be carried by the tire. When
replacing the tires on the vehicle, al-
ways use a tire that has the same
load rating as the factory installed
tire.

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
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
(Example: Summer, All Season or
Snow) and construction. A NISSAN
certified LEAF dealer may be able to
help you with information about tire
type, size, speed rating and
availability.
• 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
VDC system to malfunction resulting
in personal injury or death, excessive
tie wear and may damage the trans-
mission and differential gears.
• 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
TPMS.
• 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 (Mud and Snow) on
the tire sidewall. Snow tires have better
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 is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating M&S on the tire sidewall.
8-32Do-it yourself

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 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.
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 vehicles with restricted
tire to vehicle clearance. Vehicles that can
use Class “S” chains are designed to meet
the SAE standard minimum clearances be-
tween the tire and the closest vehicle sus-
pension or body component required to
accommodate the use of a winter traction
device (tire chains or cables). The minimum
clearances are determined using the fac-
tory 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
front wheels and not on the rear wheels.
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.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the
tires every 7,500 miles (12,000 km).
As soon as possible, tighten the
wheel nuts to the specified torque
using a torque wrench.Wheel nut tightening torque:83 f t-lb (113 N·m) The wheel nuts must be kept tight-
ened to the specification at all
times. It is recommended that
wheel nuts be tightened to the
specification at each tire rotation
interval.
WARNING
•
Af ter rotating the tires, check
and adjust the tire pressure.
• Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
• 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.

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
wear indicators are visible, the
tire(s) should be replaced.
• Tires degrade with age and
use. Have tires, over 6 years old
checked by a qualified techni-
cian, because some tire dam-
age may not be obvious. Re-
place the tires as necessary to
prevent tire failure and pos-
sible personal injury. •
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 “Specifications”
(P. 10-4) for recommended types and sizes
of tires and wheels.
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.
Do-it yourself8-35

•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/shoe wear. For additional infor-
mation on wheel-off set dimensions,
see “Wheels and tires” (P. 10-5).
• When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function when a wheel is re-
placed, 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. It is recommended that you
visit a NISSAN certified LEAF 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 certified LEAF 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 tire 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.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.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Care of wheels

EMERGENCY TIRE PUNCTURE
REPAIR KIT
The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can be
used to temporarily repair minor tire
punctures.
If possible, have the vehicle towed to a fa-
cility that can repair or replace the flat tire.
Using the emergency tire puncture repair
kit may cause a malfunction of the tire
pressure sensor and cause the low tire
pressure warning light to illuminate.
For additional information, see “Flat tire”
(P. 6-3).
