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
IMPORTANT TIRE SAFETY INFORMATION¹

44IMPORTANT TIRE SAFETY INFORMATION¹
result in tire destruction. When inspecting
your tires, including the spare, check your air
pressures. If your pressure check indicates
that one of your tires has lost pressure of two
pounds or more, look for signs of penetrations,
valve leakage, or wheel damage that may
account for the air loss.
All tires will wear out faster when subjected
to high speeds as well as hard cornering, rapid
starts, sudden stops, frequent driving on roads
which are in poor condition, and off-road use.
Roads with holes and rocks or other objects
can damage tires and cause misalignment of
your vehicle. When you drive on such roads,
drive on them carefully and slowly, and before
driving again at normal or highway speeds,
examine your tires for any damage, such
as cuts, bulges, penetrations, unusual wear
patterns, etc.
TREAD WEAR INDICATORS (WEAR BARS):
Tires contain Tread Wear Indicators (Wear
Bars) in the grooves of the tire tread which
show up when only 2/32nds of an inch
(1.6mm) of tread is remaining. At this stage,
your tires must be replaced. Tires worn beyond
this stage are dangerous.
HAZARDS
Objects in the road that threaten a tire should
be safely avoided. These objects are potholes,
glass, metal, rocks, wood debris and the
like. Unavoidable contact should prompt a
thorough tire inspection. You may not always recall hitting an object
that can damage or injure your tires. If while
driving your vehicle experiences any unusual
vibrations, ride disturbance or noise and/or you
suspect that possible damage to the tires or
vehicle has occurred, DO NOT JAM OR LOCK
YOUR BRAKES! Rather reduce your speed and
drive with caution until you can safely pull off
the road. Stop and inspect the tires. If the tire
is underinflated or damaged, deflate, remove
the tire and rim assembly and replace it with
your spare. If you cannot detect a cause, have
the vehicle towed to the nearest vehicle or tire
retailer to have the vehicle inspected.
REPAIRING, MOUNTING AND
DEMOUNTING OF TIRES
Do not attempt to repair, mount or demount a
tire yourself. Tire changing can be dangerous
and must be done by professionally trained
persons using proper tools and procedures
as specified by the Rubber Manufacturers
Association (RMA). Follow these mounting
recommendations. Your tires should be
mounted on wheels of correct size and type
and which are in good, clean condition. Bent,
chipped or rusted wheels may cause tire
damage. The inside of the tire must be free
from foreign materials. Have your retailer
check the wheels before mounting new tires.
Mismatched tires and rims can explode during
mounting. Also, mismatched tires and rims can
result in dangerous tire failure on the road. If
a tire is mounted by error on the wrong-sized
rim, do not remount it on the proper rim - scrap it. It may be damaged internally (which
is not externally visible) by being dangerously
stretched and could fail on the highway.
Old valves may leak. When new tubeless tires
are mounted, have new valves of the correct
type installed. Tubeless tires must be mounted
only on wheels designed for tubeless tires, i.e.,
wheels which have safety humps or ledges.
Never perform a temporary repair, use an
innertube or inject sealant as a permanent
substitute for a proper repair. Only qualified
persons should repair tires.
Be sure that all your valves have suitable valve
caps. This will keep valve cores clean and clear
and guard against leakage.
REPAIRS - WHENEVER POSSIBLE, SEE
A TIRE RETAILER AT ONCE.
Some tire
manufacturers do not warrant any inspection
or repair process. The repair is entirely the
responsibility of the repairer. Punctures in
the tread of a passenger tire which do not
exceed 1/4 of an inch (6mm) in diameter can
usually be repaired by following the Rubber
Manufacturer’s Association (RMA) Passenger
and Light Truck Repair procedures. Contact
the manufacturer of your tires for its position
and assistance as to the acceptable location
for a proper repair and the repair of speed
rated tires. Do not use plug repairs. They may
cause further damage to the tire. They are not
always air tight and the plug may fail. Do not
exceed posted speed limits on any repaired tire.
(Continued on next page)

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
IMPORTANT TIRE SAFETY INFORMATION¹

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.
