flat tire INFINITI G 2011 Owner's Manual

Checking the tire pressure
1.Remove the valve stem cap from the
tire.
2.Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.
3.Remove the gauge.
4.Read the tire pressure on the gauge
stem and compare it to the specifica-
tion 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 re-
lease 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 manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamen-
tal characteristics of the tire and also
provides 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: P215/60R16 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 num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3.Two-digit number (60): This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.
Example
SDI1575
Example
SDI1606
Maintenance and do-it-yourself8-35

4.R: The “R” stands for radial.
5.Two-digit number (16): This number is
the wheel or rim diameter in inches.
6.Two- or three-digit number (94): 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 iden-
tification mark
3.Two-digit code: Tire size
4.Three-digit code: Tire type code (Op-
tional)
5.Three-digit code: Date of Manufacture
6.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 side-
wall of the tire.
3Tire 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.
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 inflation pressure.

CHANGING WHEELS AND TIRES
Tire rotation (Models equipped with
same size tires on all wheels)
INFINITI recommends rotating the tires
every 7,500 miles (12,000 km). (See
“FLAT TIRE” in the “6. In case of emer-
gency” section for tire replacing proce-
dures.)
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·m)
The wheel nuts must be kept tightened to
the specification at all times. It is recom-
mended that wheel nuts be tightened to
the specification at each tire rotation in-
terval.
WARNING
●After rotating the tires, check and ad-
just the tire pressure.
●Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
●Do not include the T-type spare tire or
any other small size spare tire in the tire
rotation.
●For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Tire rotation (Models equipped with
different size tires on front and rear)
Tires cannot be rotated on this vehicle,
as front tires are a different size from
rear tires.
A pin is on the front brake rotor to
prevent 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 installing
the spare tire in the front wheel, the hole
in the spare tire wheel must be aligned
with the pin on the brake rotor.
WARNING
●Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).

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 performed 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
INFINITI Warranty Information Booklet.
Care of wheels
See “CLEANING EXTERIOR” in the “7. Appear-
ance and care” section for details about care of
the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
WARNING
●The T-type spare tire should be used for
emergency use. It should be replaced with
the standard tire at the first opportunity to
avoid possible tire or differential damage.
● Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
● Periodically check spare tire inflation pres-
sure. Always keep the pressure of the TEM-
PORARY USE ONLY spare tire at 60 psi (420
kPa, 4.2 bar). Always keep the pressure of
the full size spare tire (if so equipped) at the
recommended pressure for standard tires,
as indicated on the Tire and Loading Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
● With the TEMPORARY USE ONLY spare tire
installed do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
● When driving on roads covered with snow or
ice, the TEMPORARY USE ONLY spare tire
should be used on the front wheels and origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the two rear
original tires. ●
Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than the
standard tire. Replace the spare tire as soon
as the tread wear indicators appear.
● Do not use the spare tire on other vehicles.
● Do not use more than one spare tire at the
same time.
● Do not tow a trailer when the TEMPORARY
USE ONLY spare tire is installed.
CAUTION
●Do not use tire chains on a TEMPORARY USE
ONLY spare tire. Tire chains will not fit prop-
erly and may cause damage to the vehicle.
● Because the TEMPORARY USE ONLY spare
tire is smaller than the original tire, ground
clearance is reduced. To avoid damage to the
vehicle, do not drive over obstacles. Also do
not drive the vehicle through an automatic
car wash since it may get caught.

3.Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
4.The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the XXX
amount equals 1400 lbs. and there
will be five 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs. (1400750 (5 x 150) = 650
lbs or 640 340 (5 x 70) = 300 kg.)
5.Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
6.If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this re-
duces the available cargo and lug-
gage load capacity of your vehicle. Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
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 pres-
sures. See the Tire and Loading Informa-
tion label.
LOADING TIPS
●The GVW must not exceed GVWR or
GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification la-
bel.
●Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING
●Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seatbacks.
In a sudden stop or collision, unsecured
cargo could cause personal injury.
●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 oc-
cur, or it can change the way your ve-
hicle handles. This could result in loss
of control and cause personal injury.
●Overloading could not only shorten the
life of your vehicle and the tires, but
also could lead to hazardous vehicle
handling and long braking distance.
This may cause a premature tire mal-
function, which could result in a serious
accident and personal injury. Failures
caused by overloading are not covered
by the vehicle’s warranty.
Technical and consumer information9-21

DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
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 rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment 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
depends upon actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
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 mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hy-
droplaning, or peak traction characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B, and
C, representing the tire’s resistance 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 ma-
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A rep-
resent higher levels of performance on the
laboratory test wheel than the minimum re-
quired by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and not
overloaded. Excessive speed, under-inflation,
or excessive loading, either separately or in
combination, can cause heat build-up and pos-
sible tire failure.
