DON’T ATTEMPT TO MOUNT YOUR OWN TIRES
Serious injury or Death may result from explosion of
tire/ rim assembly due to improper mounting proce-
dures. 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 sur-
faces. 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 Dun-
lop 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. Ve-
hicle 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 se-
lected. Never exceed the maximum load capacity and
inflation pressure listed on the sidewall of the tire. Al-
ways drive safely and obey all traffic laws. Avoid sud-
den, sharp turns or lane changes. Failure to follow thiswarning may result in loss of control of the vehicle,
leading to an accident and serious injury or death.
When replacing tires, you must maintain the outside
diameter and load carrying capacity of the Original
Equipment tire. Inflation pressure may need to be ad-
justed to avoid overloading the tire. Consult the Tire &
Rim Association Load and Inflation Tables, ETRTO or
JATMA standards for correct load and inflation informa-
tion.
NEVER FIT TIRES TO A VEHICLE THAT HAVE
LESS LOAD CARRYING CAPACITY THAN AS
REQUIRED BY THE ORIGINAL EQUIPMENT
MANUFACTURER
Examples: Many vehicles, such as large passenger
vans, require Load Range E tires as designated by the
vehicle manufacturer. Fitment of a tire, such as a Load
Range D, with less carrying capacity is not allowed.
In other cases, tires of the same size may carry different
load indexes in the service description. You must make
certain the replacement tires fitted to the vehicle have a
load carrying capacity equal to or greater than what the
Original Equipment manufacturer specifies.
NOTE:
Goodyear manufactured and/or marketed European-
Metric passenger tires and P-Metric passenger tires are
interchangeable as long as they have the same section
width, same aspect ratio, same rim diameter. Caution:
Never substitute a “Standard Load” (SL) tire for an Extra
Load (XL) tire. If the vehicle was originallyequipped
with “Extra Load” (XL) tires, replace those tires with
similar sized XL tires.
FOLLOW THESE ADDITIONAL GUIDELINES
When installing only two tires, fit the tires with the
deepest tread depth on the rear axle. If radials and
non-radials must be fitted to the same vehicle, fit radials
on rear axle. Never mix radials and non-radials on the
same axle. When fitting snow tires or all-season tires to
performance vehicles, always fit in sets of four. It is not
recommended to fit tires with different speed ratings. If
tires with different speed ratings are installed on a ve-
hicle, they should be installed with like pairs on the
same axle. The speed capability of the vehicle will be-
come limited to that of the lowest speed rated tires.
Use of lift kits with some vehicle/tire combinations can
cause instability. When changing tire sizes, always con-
sult Dealer for optimum rim width and carefully checkvehicle/tire clearances.
RETREADED TIRES
Retreaded passenger and light truck tires are not war-
ranted by Goodyear and Dunlop for any reason. Good-
year and Dunlop speed ratings and U.S. Department of
Transportation test compliance certifications are voided
for retreaded tires.
DO MAINTAIN VEHICLESUSPENSION, WHEEL
ALIGNMENT AND BALANCE AND ROTATE YOUR
TIRES
Lack of rotation, worn suspension parts, underinflation/
overinflation, wheel imbalance and misalignment can
cause vibration or irregular tire wear. Rotate your tires
according to your vehicle manufacturer’s recommenda-
tions or at maximum intervals of 6,000 miles/10,000 km.

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 Manualfor loca-
tion.) These inflation pressures must be maintained as a
minimum. However, do not exceed the maximum pres-
sure rating indicated on the tire sidewall.
CHECK INFLATION PRESSURES ON ALL YOUR TIRES, IN-
CLUDING THE SPARE, WHEN TIRES ARE COLD, AT LEAST
ONCE A MONTH BEFORE DRIVING.
Failure to maintain correct inflation may result in im-
proper vehicle handling and may cause rapid and ir-
regular tire wear, sudden tire destruction, loss of vehicle
control and serious personalinjury. 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 recom-
mended cold air pressure. Recheck the inflation pres-
sure 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 COR-
RECT INFLATION PRESSURE IS DANGEROUS. For replace-
ment 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 side-
walls 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 op-
erate 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.How-
ever, 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 avail-
able 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.

HARD BRAKING
You must inspect your tires after any hard braking cir-
cumstances 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 explo-
sion, resulting in vehicle damage and/or serious per-
sonal 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 auto-
matic 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 bal-
ancing 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 haz-
ards. 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 recom-
mended that the same size and type of tire be used on
all four wheel positions. In certain tires, casing ply ma-
terial 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 recom-
mendations.
Tires which meet the Rubber Manufacturer’s Associa-
tion (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 equip-
ment tires. Always fit performance snow tires in sets of
four (4) for optimum mud & snow traction and mainte-
nance of vehicle handling characteristics. If you do not,
it may adversely affect thesafety and handling of your
vehicle. It is also important to check the vehicle Owner’s
Manual before mixing or matching tires on 4-wheel drivevehicles as this may require special precautions.
Please refer to your Owner’s Manual for more informa-
tion 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 rota-
tion 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.
