tires INFINITI G35 2006 Owner's Guide

mends 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 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 operate your vehicle in snowy or icy
conditions, INFINITI recommends the use
of snow or all season tires on all four
wheels.
For additional traction on icy roads, stud-
ded tires may be used. However, some
provinces and states prohibit their use.
Check local, state and provincial laws be-
fore 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. All-wheel drive (AWD) models
CAUTION O Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), 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 will
cause excessive tire wear and may
damage the transmission, transfer case
and differential gears.
O 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, con-
struction and tread pattern. The tire pres-
sure and wheel alignment should also be
checked and corrected as necessary. Con-
tact an INFINITI dealer.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved
roads which are clear of snow. Driving with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
TIRE CHAINS Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When install-
ing tire chains, make sure they are the
proper size for the tires on your vehicle
and are installed according to the chain
manufacturer's suggestions. Use only SAE
class ªSº chains. Class ªSº chains are
used on vehicles with restricted tire to ve-
hicle clearance. Vehicles that can use
Class ªSº chains are designed to meet
the minimum clearances between the tire
and the closest vehicle suspension or
body component required to accommo-
date the use of a winter traction device
(tire chains or cables). The minimum
clearances are determined using the fac-
tory equipped tires. Other types may
damage your vehicle. Use chain ten-
sioners 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 possi-
bility 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
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use the chains on dry roads. Driv-
ing with chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.
CHANGING WHEELS AND TIRES Tire rotation (Sedan)
INFINITI recommends rotating the tires
every 7,500 miles (12,000 km).
See ªFlat tireº in the ª6. In case of
emergencyº section for tire replacing
procedures.
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque:
80 ft-lb (108 N z m) The wheel nuts must be kept tightened
to specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation in-
terval.
WARNING O After rotating the tires, check and
adjust the tire pressure.
O Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) (also in cases of a
flat tire, etc.).
O Do not include the T-type spare
tire or any other small size spare
tire in the tire rotation.
O For additional information re-
garding tires, refer to ªImportant
Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada)
in the Warranty Information
Booklet.

rear tires and the direction of the wheel
rotation is fixed for each tire.
A pin is on the front brake rotor to pre-
vent the rear wheels from being in-
stalled in place of the front wheels. The
spare tire can be installed in place of
the front and rear wheels. When install-
ing the spare tire in the front wheel, the
hole in the spare tire wheel must be
aligned with the pin on the brake rotor.
WARNINGO Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) (also in cases of a
flat tire, etc.).

Tire wear and damage
WARNINGO 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. O The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
O 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 obvious.
Replace the tires as necessary to
prevent tire failure and possible
personal injury.
O Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an INFINITI
dealer.
O For additional information re-
garding tires, refer to ªImportant

tionsº in the ª9. Technical and consumer
informationº section for recommended
types and sizes of tires and wheels.
WARNINGO 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 ad-
versely affect the ride, braking, handling,
ground clearance, body-to-tire clearance,
tire chain clearance, speedometer calibra-
tion, headlight aim and bumper height.
Some of these effects may lead to accidents
and could result in serious personal injury.
O If the wheels are changed for any reason,
always replace with wheels which have
the same off-set dimension. Wheels of a
different off-set could cause premature
tire wear, degrade vehicle handling char-
acteristics and/or interference with the
brake discs. Such interference can lead
to decreased braking efficiency and/or
early brake pad wear.
O When a spare tire is mounted or a wheel
is replaced, tire pressure will not be indi-
cated, the TPMS will not function and the low tire pressure warning light will flash.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or sys-
tem resetting.
O Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
O Do not install a deformed wheel or tire
even if it has been repaired. Such wheels
or tires could have structural damage
and could malfunction without warning.
O The use of retread tires is not recom-
mended.
O For additional information regarding tires,
refer to ªImportant Tire Safety Informationº
(US) or ªTire Safety Informationº (Canada)
in the Warranty Information Booklet.
CAUTION Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), 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 will cause excessive tire
wear and may damage the transmission,
transfer case and differential gears (AWD
models).
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 per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to transmission damage.
For additional information regarding tires,
refer to ªImportant Tire Safety Informa-
tionº (US) or ªTire Safety Informationº
(Canada) in the INFINITI Warranty Informa-
tion Booklet.
Care of wheels O Wash the wheels when washing the
vehicle to maintain their appearance.
O Clean the inner side of the wheels
when the wheel is changed or the un-
derside of the vehicle is washed.

O Do not use abrasive cleaners when
washing the wheels.
O Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
O INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
Spare tire (TEMPORARY USE ONLY
spare tire (T-type)) Observe the following precautions if the
T-type spare tire must be used, otherwise
your vehicle could be damaged or in-
volved in an accident.
CAUTIONO The T-type spare tire should be used only
for an emergency. It should be replaced by
a standard tire at the first opportunity.
O Drive carefully while the T-type spare tire
is installed.
Avoid sharp turns and abrupt braking
while driving. O Periodically check the T-type spare tire
inflation pressure, and always keep it at
60 psi (420 kPa, 4.2 bar).
O With the T-type spare tire installed, do
not drive your vehicle at speeds faster
than 50 MPH (80 km/h).
O When driving on roads covered with
snow or ice, the T-type spare tire should
be used on the front wheel and the origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the rear
two original tires (Sedan).
O
Tire tread of the T-type spare tire will wear
at a faster rate than the original tire. Re-
place the T-type spare tire as soon as the
tread wear indicators appear.
O Do not use the T-type spare tire on other
vehicles.
O Do not use more than one T-type spare
tire at the same time.
O Do not tow a trailer while the T-type
spare tire is installed. CAUTION O Do not use tire chains on a T-type spare
tire. Tire chains will not fit properly on
the T-type spare tire and may cause
damage to the vehicle.
O Because the T-type spare tire is smaller
than the original tire, ground clearance
is reduced. To avoid damage to the ve-
hicle do not drive over obstacles. Also do
not drive the vehicle through an auto-
matic car wash since it may get caught.

the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
Before driving a loaded vehicle, confirm
that you do not exceed the Gross Ve-
hicle Weight Rating (GVWR) or the
Gross Axle Weight Rating (GAWR) for
your vehicle. See ``Measurement of
Weights'' later in this section.
Also check tires for proper inflation
pressures. See the Tire and Loading In-
formation label.
LOADING TIPS
O The GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S./C.M.V.S.S. certification
label.
O Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
WARNINGO Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could cause
personal injury.
O Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs. If
you do, parts of your vehicle can
break, tire damage could occur, or
it can change the way your vehicle
handles. This could result in loss
of control and cause personal
injury. O Overloading not only can shorten
the life of your vehicle and the tire,
but can also cause unsafe vehicle
handling and longer braking dis-
tances. This may cause a prema-
ture tire failure which could result
in a serious accident and personal
injury. Failures caused by over-
loading are not covered by the ve-
hicle's warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh the
front and the rear wheels separately to
determine axle loads. Individual axle
loads should not exceed either of the
gross axle weight ratings (GAWR). The
total of the axle loads should not ex-
ceed the gross vehicle weight rating
(GVWR). These ratings are given on the
vehicle certification label. If weight rat-
ings are exceeded, move or remove
items to bring all weights below the rat-
ings. Technical and consumer information

CAUTIONO Do not use axle-mounted hitches.
O The hitch should not be attached to or af-
fect the operation of the impact-
absorbing bumper.
O Do not modify the vehicle exhaust
system, brake system, etc. to install a
trailer hitch.
O To reduce the possibility of additional
damage if your vehicle is struck from the
rear, where practical, remove the hitch
and/or receiver when not in use.
O After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water or
dust from entering the passenger com-
partment.
O Regularly check that all trailer hitch
mounting bolts are securely mounted. Tire pressures
O When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire
and Loading Information label.
O Trailer tire condition, size, load
rating and proper inflation pressure
should be in accordance with the
trailer and tire manufacturers' speci-
fications.
Safety chains Always use a suitable chains between
your vehicle and the trailer. The 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 cor-
ners.
Trailer lights
CAUTION When splicing into the vehicle electrical sys-
tem, a commercially available power-type module/converter must be used to provide
power for all trailer lighting. This unit uses
the vehicle battery as a direct power source
for all trailer lights while using the vehicle
tail light, stoplight and turn signal circuits
as a signal source. The module/converter
must draw no more than 15 milliamps from
the stop and tail lamp circuits. Using a
module/converter that exceeds these power
requirements may damage the vehicle's
electrical system. See a reputable trailer
dealer to obtain the proper equipment and to
have it installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an
INFINITI dealer or reputable trailer dealer.
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
properly installed.

O For emergency towing procedures refer
to ªTowing recommended by INFINITIº in
the ª6. In case of emergencyº section of
this manual.
Automatic transmission To tow a vehicle equipped with an auto-
matic transmission, an appropriate ve-
hicle dolly MUST be placed under the
towed vehicle's drive wheels. Always
follow the dolly manufacturer's recom-
mendations when using their product.
Manual transmission O Always tow with the manual transmis-
sion in Neutral.
O After towing 500 miles, start and idle
the engine with the transmission in
Neutral for two minutes. Failure to idle
the engine after every 500 miles of
towing may cause damage to the
transmission's internal parts. DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements 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 The treadwear grade is a comparative rat-
ing based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would wear
one and one-half (1 1/2) times as well on
the government course as a tire graded
100. The relative performance of tires de-
pends upon the actual conditions of their
use, however, and may depart signifi-
cantly from the norm due to variations in
driving habits, service practices and dif-
ferences in road characteristics and cli-
mate.
Traction AA, A, B and C The traction grades, from highest to
lowest, are AA, A, B, and C. Those grades represent the 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 may have poor traction perfor-
mance.
WARNING The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction char-
acteristics.
Temperature A, B and C The temperature grades A (the highest),
B, and C, representing the tire's resis-
tance to the generation of heat and its
ability to dissipate heat when tested
under controlled conditions on a specified
indoor laboratory test wheel. Sustained
high temperature can cause the material
of the tire to degenerate and reduce tire
life, and excessive temperature can lead
to sudden tire failure. The grade C corre-
sponds to a level of performance which
all passenger car tires must meet under
the Federal Motor Safety Standard No.UNIFORM TIRE QUALITY GRADING
