TO PROLONG TIRE LIFE DURING A SYSTEM
ALERT
The Goodyear or Dunlop Run-Flat tire can be
driven at low or zero air pressure (refer to your
vehicle Owner’s Manual for these limitations).
To help prolong the life of a tire operating
under low-inflation conditions, drive at a speed
as far below 50 mph (80 kph) as possible. Also,
drive the shortest distance possible before
obtaining tire service. Taking these precautions
will increase the chance that your tire will be
repairable.
SERVICE AFTER A SYSTEM ALERT
To obtain service after operating under low-
inflation conditions, contact your Goodyear or
Dunlop Run-Flat service facility. Trained service
personnel will inspect your tires to determine
if they are in need of repair or replacement.
To locate the nearest authorized Goodyear or
Dunlop Run-Flat service facility, call 1-800-
GOODYEAR (1-800-466-3932).
WARNING
Because of the unique characteristics of
Run-Flat tires, the wheels on which they
are mounted and your vehicle’s tire pressure
monitoring system, all tire service work other
than routine inflation maintenance and
external inspections must be performed by
service personnel at a Goodyear or Dunlop
Run-Flat service facility. Do not attempt to
mount or demount Run-Flat tires yourself;
serious injury or death could result. Only
specially trained persons should mount,
demount and repair Run-Flat tires, and more than 40 psi (270 kPa) may be required to seat
beads. A safety cage and clip-on extension
air hose must be used if more than 40 psi
(270kPa) is need to seat beads.
TIRE REPAIR
Like any other Goodyear or Dunlop speed-
rated, high performance tire, the Goodyear
or Dunlop Run-Flat tire may be repaired to
correct a puncture in the tread, but PROPER
MATERIALS AND PROCEDURES MUST BE
USED. Contact a Goodyear or Dunlop Run-
Flat service facility for information on proper
repairs. For the location of the nearest facility,
call 1-800-GOODYEAR (1-800-466- 3932).
WARNING
Goodyear and Dunlop Run-Flat tires are
designed for use only on certain original
equipment wheels supplied with a properly
operating low tire pressure-monitoring system.
If applied to a vehicle without a properly
operating low tire pressure-monitoring
system, the tires may fail when operated in
an underinflated condition, resulting in loss of
vehicle control and possible serious injury or
death. Application of these tires to a vehicle
not equipped with specified operational low
tire pressure monitoring system constitutes
improper and unsafe use of this product.OPERATIONAL MONITORINGThe information contained in this Limited
Warranty Brochure applies only to the Original
Equipment tires supplied with your vehicle.
In order for Goodyear Run-Flat (Extended
Mobility Technology [EMT], RunOnFlat [ROF])
or Dunlop Run-Flat (Dunlop Self- Supporting
Technology [DSST]) tires to obtain the
performance criteria stated within this Limited
Warranty, Goodyear or Dunlop Run- Flat tires
must use specific parts, such as a low tire
pressure monitoring system authorized by the
Original Equipment vehicle manufacturer.
RUN-FLAT TIRE FEATURE:The Goodyear or Dunlop Run-Flat tire is a high
performance tire with a remarkable feature:
It can operate for limited distances with very
low or even no inflation pressure (refer to your
Vehicle Owner’s Manual for these limitations).
This is an important benefit, especially if
inflation loss occurs at a location where
immediately stopping your vehicle could be
hazardous.

TIRE PRESSURE MONITORING
SYSTEM ALERT
Refer to your vehicle Owner’s Manual for more
information on what to do if the tire pressure
warning system activates.
WARNING
If the tire pressure-monitoring system signals
an alert, follow these safety precautions to
prevent a loss of vehicle control that could
result in serious personal injury or death:
• Slow your speed. Do not exceed 50 mph (80 kph).
• Avoid hard cornering, hard braking and severe handling maneuvers.
• Avoid potholes and other road hazards
Remember that when your tires have lost air
pressure, your vehicle’s handling capability is
reduced, particularly during severe maneuvers.

42IMPORTANT TIRE SAFETY INFORMATION¹
Any tire, no matter how well constructed,may
fail due to improper maintenance or
service factors. This could create a risk of
property damage and serious or fatal injury.
Disregarding any of the safety precautions
and instructions contained in this manual may
result in tire failure or explosion causing serious
personal injury or death. For your safety,
comply with the following:
TIRE INFLATION
Keep tires inflated to the pressures
recommended on the tire data placard. (See
your Owner’s Manual for location.) These
inflation pressures must be maintained as a
minimum. However, do not exceed the maximum
pressure rating indicated on the tire sidewall.
CHECK INFLATION PRESSURES ON ALL
YOUR TIRES, INCLUDING THE SPARE,
WHEN TIRES ARE COLD, AT LEAST ONCE A
MONTH BEFORE DRIVING.
Failure to maintain correct inflation may
result in improper vehicle handling and may
cause rapid and irregular tire wear, sudden tire
destruction, loss of vehicle control and serious
personal injury. Therefore, inflation pressures
should be checked at least once a month and
always prior to long distance trips.
Pressures should be checked when tires are
cold. The tires are cold when your vehicle has
been driven less than a mile at moderate speed
after being stopped for three or more hours.
CHECKING PRESSURE WHEN
TIRES ARE HOT
If you must add air when your tires are hot, add
four pounds per square inch (psi) (28kPa) above
the recommended cold air pressure. Recheck the
inflation pressure when the tire is cold.
For Example Only:
Gauge reading of hot tire: 32psi
If recommended pressure is: 30psi
Desired gauge reading of hot tire 30 + 4psi =
34psi
Check cold pressures as soon as possible, at
least by the next day. Never “bleed” air from
hot tires as your tire will be underinflated. Use
an accurate tire gauge to check pressures.
Never allow children to air up tires.
DRIVING ON ANY TIRE THAT DOES
NOT HAVE THE CORRECT INFLATION
PRESSURE IS DANGEROUS. For replacement
tires, the correct inflation pressure will be
provided by your tire retailer. If not, refer to the
vehicle decal.
Underinflation produces extreme flexing of the
sidewalls and builds up heat which may result
in sudden tire destruction and serious personal
injury. Overinflating can cause the tire to be
more susceptible to impact damage.
LOAD LIMITS
DO NOT OVERLOAD. DRIVING ON ANY
OVERLOADED TIRE IS DANGEROUS. Never
load your tires beyond the load carrying limits molded into the sidewall of the tires or the
maximum vehicle load limit as shown on the
vehicle tire data placard, whichever is less.
Overloading causes heat to build up which
can lead to sudden tire failure and serious
personal injury.
SPEED LIMITS AND SPEED RATED
TIRES
HIGH SPEED DRIVING CAN BE
DANGEROUS. Never operate your vehicle
in excess of lawful speeds or the maximum
speeds justified by the driving conditions.
Excessive speeds or racing can cause heat
buildup in a tire leading to possible failure and
serious personal injury.
Correct inflation pressure is especially
important.
However, at high speeds, even with
the correct inflation pressure, a road hazard,
for example, is more difficult to avoid and if
contact is made, there is a greater chance of
causing tire damage than at the lower speed.
Moreover, driving at high speed reduces the
reaction time available to avoid accidents and
bring your vehicle to a safe stop. If you see any
damage to a tire or wheel, replace it with your
spare tire and see your tire retailer at once.
Tire speed ratings do not imply that a vehicle
can be safely driven at the maximum speed
for which the tire is rated. In addition, some
damages or improper repairs may cause a
speed-rated tire to lose its speed rating.
Exceeding the tire’s maximum speed rating

will cause the tire to build up excessive heat
which can cause tire damage that could result
in sudden tire destruction and rapid air loss.
Failure to control a vehicle with sudden air loss
can lead to an accident. In any case, you should
not exceed reasonable speeds as indicated by
the legal limits and driving conditions.
SPEED SYMBOLS -are shown on the sidewall
of some tires. The following table shows the
maximum speed corresponding to the symbol.SPEED RATINGS

*Some V (or VR) rated tires may have a
speed capacity of greater than 149 mph
(240 km/h). Consult your tire manufacturer
for maximum speed ratings if your vehicle
capability exceeds this speed. **Z (or ZR) rated tires are designed for use
on cars with maximum speed capabilities
in excess of 149 mph (240 km/h). Consult
your tire manufacturer for maximum speed
capabilities.
†Although a tire may be speed rated, we do
not endorse the operation of any vehicle in
an unsafe or unlawful manner. Speed ratings
are based on laboratory tests which relate
to performance on the road, but are not
applicable if tires are underinflated, overloaded,
worn out, damaged, altered, improperly
repaired, or retreaded. Furthermore, tire speed
ratings do not imply that vehicles can be safely
driven at the maximum speed for which the tire
is rated, particularly under adverse road and
weather conditions or if the vehicle has unusual
characteristics. Most highway passenger
tires that do not have a speed symbol in the
sidewall have a maximum speed rating of 105
mph. Light truck highway tires that do not
have a speed symbol on the sidewall of the tire
have a maximum speed of 87 mph. Some light
truck tires may have higher maximum speeds;
consult your tire retailer. The speed and other
ratings of retreaded tires are assigned by the
retreader and voids the original manufacturer’s
ratings.
IMPORTANT: In order to maintain the speed
capability of the vehicle, replacement tires
must have speed ratings equal to or higher
than those fitted as original equipment (as
indicated on the vehicle placard or Owner’s
Manual). If tires with lower speed ratings are
fitted, the speed capability of the vehicle will be
lowered to the maximum speed capability of
the replacement tire as indicated on the above
table.
Remember...High speed driving can be
dangerous and may be damaging to your tires.
And...When driving at highway speeds, correct
inflation pressure is especially important.
Contact the manufacturer of your tires for
their position and assistance on the repair of
speed-rated tires. When you are replacing tires
that have a speed rating, you must replace
with tires of the same or higher speed rating
if the speed capability of the vehicle is to be
maintained.
VISUAL INSPECTION
INSPECT YOUR TIRES. DO NOT DRIVE ON A
DAMAGED TIRE OR WHEEL.
Check your tires
frequently for scrapes, bulges, separations,
cuts, snags, cracks, penetrations or excessive
localized wear from hard braking. Also check
for abnormal tire wear, particularly on the
edges of the tire tread which may be caused
by misalignment or underinflation. Impacts can
damage the inner portion of the tire without
being visible on the outside. If damage can be
seen on the tires or wheels, or if you suspect
that possible impact damage may have
occurred, replace with spare at once and have
your tire store or retailer inspect your tires
immediately. Use of a damaged tire could

mixing tires of different types on a vehicle in
any configuration, be sure to check the vehicle
Owner’s Manual for its recommendations.
Tires which meet the Rubber Manufacturer’s
Association (RMA) definition of mud and
snow tires are marked M/S, M+S, M&S. On
such tires, this designation is molded into the
sidewall. Tires without this notation are not
recommended for mud and/or snow driving.
If snow tires are needed, it is necessary
to select tires equivalent in size and load
rating to the original equipment tires.
Always fit performance snow tires in sets of
four (4) for optimum mud & snow traction
and maintenance of vehicle handling
characteristics. If you do not, it may adversely
affect the safety and handling of your vehicle.
It is also important to check the vehicle
Owner’s Manual before mixing or matching
tires on 4-wheel drive vehicles as this may
require special precautions.
Please refer to your Owner’s Manual for more
information on tire replacement precautions.
TIRE ROTATION
Tires on your Infiniti vehicle should be rotated
every 7,500 miles or as irregular wear
develops. If irregular wear becomes apparent
or if the wear rate on the tires is perceptibly
uneven, the tires should be rotated in such
a way to alleviate the problem. Check your
vehicle for any mechanical problems and
correct if necessary. Any rotation pattern or
procedure may be followed including those indicated in the Owner’s Manual. Some tires
have arrows on the sidewall showing the
direction in which the tire should turn. When
rotating this type of tire, care must be taken
to maintain the proper turning direction as
indicated by the arrows. Some vehicles have
different tire sizes specified for front and rear
axles. Tires on these vehicles should not be
rotated side to side (unless they are non-
directional). Where a temporary type spare tire
is available, it should not be included in the tire
rotation schedule. Such tires are intended for
temporary use only.
REPLACING TWO TIRES
If your vehicle was originally equipped with
four tires that were the same size and you are
only replacing 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.
TRAILER TOWING
If you anticipate towing a trailer, you should
see a tire retailer for advice concerning the
correct size of tire and pressure. Tire size and
pressure will depend on the type and size of
the trailer and hitch utilized, but in no case
must the maximum cold inflation pressure or
the tire load rating be exceeded. Check the tire
decal and your Owner’s Manual for further
recommendations on trailer towing.
TIRE ALTERATIONS
Do not perform any alterations on your tires.
Alterations may prevent proper performance,
leading to tire damage, which can result in an
accident. Tires which become unserviceable
due to alterations such as truing, whitewall
inlays, addition of balancing or sealant liquids,
may be excluded from warranty coverage.
Consult your tire warranty.
HIGH-PRESSURE TEMPORARY
SPARE TIRES
1.
The high-pressure spare tire in your Infiniti
vehicle is designed for temporary use only
and must not be used continually as a
regular tire. The standard tire should be
repaired and/or replaced as soon as possible.
2. Avoid driving over obstacles that may
damage the tire through impact or cutting,
such as potholes, glass, metal, etc.
3. Speed must not exceed 50mph (80km/h) for
non-speed-rated temporary spare tires.
4. Temporary spare tires have a limited
treadlife which can vary depending on road
conditions and your driving habits. The
spare tire should be returned to the trunk as
soon as the standard tire can be repaired or
replaced.
5. Because the high-pressure spare tire was specifically designed for your car, it should
not be used on any other vehicle.
6. Do not use snow chains on your high- pressure spare. This could cause damage to
your vehicle.
IMPORTANT TIRE SAFETY INFORMATION¹
(Continued on next page)

47
7. Check the tire’s cold inflation pressure
monthly and maintain at 60psi (4.2kg/cm2)
even when not in use.
8. The high-pressure spare tire should not be
used with any other rim nor should standard
tires, wheel covers, or trim rings be used on
the high-pressure spare tire rim which was
originally installed.
9. When the tread wear indicator appears on
the tire, replace it only with the same type
spare tire.
10. Do not enter an automatic carwash with a
temporary spare tire fitted.
11. Do not make a sharp turn or apply the brakes suddenly when driving on a high-
pressure temporary spare.
NOTE: When using any temporary type spare
tire, be sure to follow the vehicle Owner’s
Manual instructions.
TIRE STORAGE
All tires should be stored in a cool dry place
indoors so that there is no danger of water
collecting inside them.
When tires are stored they should be stored
in a cool place away from sources of heat
and ozone such as hot pipes and electric
generators. Be sure that surfaces on which
tires are stored are clean and free from grease,
gasoline or other substances which could
deteriorate the rubber. (Tires exposed to these
materials during storage or driving could be
subject to sudden failure.)
To Avoid Damage to your Tires and Possible
Accident:
• Check tire pressure at least once a month when tires are cold and before long trips.
• Do not underinflate/overinflate.
• Do not overload.
• Drive at moderate speeds, observe legal limits.
• Avoid driving over potholes, obstacles, curbs or edges of pavement.
• Avoid excessive wheel spinning.
• If you see any damage to a tire, replace with spare and see the tire manufacturer’s
retailer or your Infiniti retailer.
