fined throughout this section, Intended Out-
board Sidewall is (1) the sidewall that con-
tains 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 particular side
that must always face outward 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. An INFINITI retailer 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 they may not match the po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•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 be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction
resulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation“ (Canada) in the Warranty In-
formation Booklet.
CAUTION
ONLY use spare tires specified for the
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 recommended
that you visit an INFINITI retailer for this
service.
Do-it-yourself8-31

All season tires
INFINITI specifies all season tires on some
models to provide good performance all year,
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 traction than all season
tires and may be more appropriate in some
areas.
Summer tires
INFINITI 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.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of snow 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 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, 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 ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Four-Wheel Drive (4WD) models
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 recommended
that you visit an INFINITI retailer.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 235/45 R19 or 235/50 R18 size tires.
Installation of the tire chains/cables on
235/45 R19 or 235/50 R18 size tires will
cause damage to the vehicle. If you plan to
use tire chains/cables, you should install
215/60 R17 size tires on your vehicle.
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 that they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s in-
structions.
Use chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chains 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 addi-
tion, 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.

TIRE ROTATION
INFINITI recommends rotating the tires ev-
ery 5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to "Flat tire" in the "6. In
case of emergency" section.As soon as pos-
sible, tighten the wheel nuts to the specified
torque with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130
N·m)
The wheel nuts must be kept tightened to
specifications at all times. It is recommended
that wheel nuts be tightened to specification
at each tire rotation interval.
WARNING
•After rotating the tires, check and ad-
just the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding
tires, refer to "Important Tire Safety In-
formation" (US) or "Tire Safety Infor-
mation" in the Warranty Information
Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even
if it has been repaired. Such wheels or tires
could have structural damage and could
fail without warning.
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. (See "Wheels and Tires" in
the "9. Maintenance and Schedules" section
for recommended types and sizes of tires and
wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to de-
creased braking efficiency and/or early brake
pad/shoe wear.
Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
•For 2WD models, if your vehicle was
originally equipped with 4 tires that
were the same size and you are only re-
placing 2 of the 4 tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of ve-
hicle control in some driving conditions
and cause an accident and personal in-
jury.
•If the wheels are changed for any rea-
son, always replace with wheels which
have the same offset dimension. Wheels
of a different offset could cause prema-
ture tire wear, degrade vehicle handling
characteristics, affect the VDC system
and/or interference with the brake
discs. Such interference can lead to de-
creased braking efficiency and/or early
8-34Do-it-yourself

brake pad wear. For additional informa-
tion on wheel offset dimensions, refer to
"Wheels and Tires" in the "9. Mainte-
nance and Schedules" section.
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately 1
minute. The light will remain on after 1
minute. Contact an INFINITI retailer as
soon as possible for tire replacement
and/or system resetting.
•Replacing tires with those not originally
specified by INFINITI could affect 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 rec-
ommended that you visit an INFINITI re-
tailer for ID registration.
•Do not use a valve stem cap that is not
specified by INFINITI. The valve stem
cap may become stuck.
•Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may be clogged up with dirt and cause a mal-
function or loss of pressure.
•Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
•The use of retread tires is not recom-
mended.
•For additional information regarding
tires, refer to "Important Tire Safety In-
formation" (US) or "Tire Safety Infor-
mation" (Canada) in the Warranty In-
formation Booklet.
Care of wheels
•Wash the wheels when washing the ve-
hicle to maintain their appearance.
•Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
•Do not use abrasive cleaners when wash-
ing the wheels.
•Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
•INFINITI recommends waxing the road
wheels to protect against road salt in ar-
eas where it is used during winter.
WHEEL BALANCE
Unbalanced wheels may affect vehicle han-
dling 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 performed
with the wheels off the vehicle. Spin balanc-
ing 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.

indicators can only be rotated between front
and rear. Make sure that the directional indi-
cators point in the direction of wheel rotation
after the tire rotation is completed.
Tires*:
Check the pressure with a gauge often and
always prior to long distance trips. Adjust the
pressure in all tires to the pressure specified.
Check carefully for damage, cuts or excessive
wear.Tire Pressure Monitoring System (TPMS)
transmitter components:
Replace the TPMS transmitter grommet seal,
valve core and cap when the tires are re-
placed due to wear or age.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
