tires. Excessively worn tires are also more
susceptible to penetrations.
DO CHECK YOUR TIRES FOR
DAMAGE
Frequent (at least monthly) inspection of your
tires for signs of damage and their general
condition is important for safety. If you have
any questions, have your tire Retailer inspect
them. Impacts, penetrations, cracks, knots,
bulges or air loss always require tire removal
and expert inspection. Never perform a
temporary repair or use an inner tube as a
substitute for a proper repair. Only qualified
persons should repair tires.
PROPER TIRE REPAIR
NOTE: Goodyear and Dunlop do not warrant
any inspection or repair process. The repair is
entirely the responsibility of the repairer and
should be made in accordance with established
Rubber Manufacturers Association (RMA)
procedures.
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.
THE CONVENIENCE (TEMPORARY)
SPARE
The Convenience (Temporary) Spare is designed,
built, and tested to the high engineering
standards set by North America’s leading car
manufacturers and to Goodyear and Dunlop’s own high standards of quality control. It is
designed to take up a minimum of storage
space and, at the same time, fulfill the function
of a spare tire when needed. The spare is kept in
its storage space, fully inflated at 60 psi. To be
sure it is always ready for use, the air pressure
should be checked on a regular basis.
The Convenience (Temporary) Spare can be
used in combination with the original tires
on your vehicle. You can expect a tire tread
life of up to 3,000 miles (4,800 kilometers),
depending on road conditions and your driving
habits. To conserve tire tread life, return the
spare to the storage area as soon as it is
convenient to have the standard tire repaired
or replaced.
The Convenience (Temporary) Spare weighs
less than a standard tire so it’s easier to handle.
It also helps reduce the total car weight which
contributes to fuel economy.
The wheels used with the Convenience
(Temporary) Spare are specifically designed for
use with high pressure spares and should never
be used with any other type tire.
DON’T ATTEMPT TO MOUNT YOUR
OWN TIRES
Serious injury or Death may result from
explosion of tire/ rim assembly due to
improper mounting procedures. Follow tire
manufacturer’s instructions and match tire
diameter to rim diameter. Mount light truck
radials on rims approved for radial service. Do
not apply bead sealer. This can inhibit bead
seating. Lubricate beads and tire rim (including
tube or flap) contact surfaces. Lock assembly
on mounting machine or place in safety cage.
STAND BACK and never exceed 40 psi to
seat beads. Never use a volatile substance or a
rubber “donut” (also known as a bead expander
or “O-Ring”) to aid bead seating. Only
specially-trained persons should mount tires.
DON’T MIX TIRES OF DIFFERENT
SIZES AND TYPES ON THE SAME
AXLE
For optimum handling and control, Goodyear
and Dunlop recommend fitment of four (4) tires
of the same type and size unless otherwise
specified by the vehicle manufacturer.
WARNING: Before you replace your tires,
always consult the vehicle Owner’s Manual and
follow the vehicle manufacturer’s replacement
tire recommendations. Vehicle handling may
be significantly affected by a change in tire
size or type. When selecting tires that are
different than the Original Equipment size,
see a professional installer in order to make
certain that proper clearance, load carrying
capacity and inflation pressure is selected.
Never exceed the maximum load capacity and
inflation pressure listed on the sidewall of the
tire. Always drive safely and obey all traffic
laws. Avoid sudden, sharp turns or lane changes.
Failure to follow this warning may result in loss
of control of the vehicle, leading to an accident
and serious injury or death.

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
1 Provided by and published at the request of the tire manufacturers/warrantors.

45
Certain tire manufacturers speed ratings are
voided if the tire is repaired.
Although a tire was properly repaired, internal
structural damage resulting from the puncture
may have occurred.
Sometime later the damage may cause the tire
to be removed from service.
If the tire has a puncture in the tread which
exceeds 1/4 inch (6mm), the tire must be
replaced. If any tire has sustained a puncture,
have the tire inspected internally by a tire
retailer for possible damage that may have
occurred.
Improper mounting and inflation procedures
can cause an explosion of the tire/rim
assembly. Only specially trained persons should
perform these tasks. Contact your tire store or
retailer for assistance.
CAUTION - Never, under any circumstance,
introduce a flammable substance into a tire.
WHEEL ALIGNMENT AND
BALANCING
Wheel alignment and balancing are important
for safety and maximum mileage from your
tires. Check how your tires are wearing at
least once a month. If your tires are wearing
unevenly, such as the inside shoulder of the
tire wearing faster than the rest of the tread,
or if you detect excessive vibration, your
vehicle may be out of alignment or balance.
These conditions not only shorten the life of
your tires, but adversely affect the handling characteristics of your vehicle which could
be dangerous. If you detect irregular wear or
vibration, have your alignment and balance
checked immediately. Tires which have been
run underinflated will show more wear on the
shoulders than in the center of the tread.
HARD BRAKING
You must inspect your tires after any hard
braking circumstances or after tires have slid
on the pavement. This can cause a flat spot in
a section of the tire tread.
TIRE SPINNING
Never spin your tires above a speedometer
reading of 35 mph (55 km/h) if your vehicle
becomes stuck. The centrifugal force
generated by the free spinning tire/wheel
assembly may cause a sudden tire explosion,
resulting in vehicle damage and/or serious
personal injury or death. Never allow anyone
to stand near or behind a tire spinning at high
speed while attempting to push a vehicle that
is stuck. When in mud, sand, snow, ice or other
slippery conditions, do not indulge in excessive
wheel spin. In such conditions, with automatic
transmission vehicles, by accelerating the
engine excessively, it is possible to spin one of
the drive tires beyond its speed capability. This
is also true when balancing a drive tire/wheel
assembly using the engine of the vehicle to
spin the wheel.
TIRE TREAD
Tires must be replaced when the depth of
the tread reaches 2/32 inch (1.6 mm). Tires
are manufactured with tread wear indicators
molded into the tire grooves which indicate
tread wearout. As tires approximate 2/32 inch
(1.6 mm) wearout, the tread gauge becomes
thinner and more vulnerable to the effects
of road hazards. Also, worn tires are more
subject to hydroplaning, which can cause loss
of control. Therefore, visual tire inspection
becomes more crucial as the tires wear out.
WORN TIRES
Never drive on worn tires. Tires should be
replaced by trained personnel when 2/32nds
of an inch tread depth remains, as indicated
by the tread wear indicators molded into the
tread grooves. In most states, it is illegal to
drive with less than 2/32nds of an inch of
tread remaining.
TIRE MIXING
For best performance select tires similar in
size and load rating to the original equipment
tires. It is recommended that the same size
and type of tire be used on all four wheel
positions. In certain tires, casing ply material
and ply construction may vary as indicated
on the sidewall of the tire. When changing
or replacing tires, it is preferred that all four
tires are the same construction type (i.e., High
Performance, All Season, Mud & Snow) and
construction (Radial or Bias Ply). Before

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.
