SAFETY WARNINGS
Property damage, serious injury or death may 
result from: 
••TIRE FAILURE DUE TO 
UNDERINFLATION/OVERLOADING/
MISAPPLICATION.
Follow the vehicle Owner’s Manual or tire 
placard in vehicle. 
••TIRE FAILURE DUE TO IMPACT DAMAGE/
IMPROPER MAINTENANCE.
Tires should be inspected regularly by a 
qualified technician for signs of damage, 
such as punctures or impacts.
••TIRE FAILURE DUE TO IMPROPER 
REPAIRS.
See Rubber Manufacturer’s Association 
(RMA) established repair procedures at 
www.rma.org and/or go to www.goodyear.
com for information on proper repair 
procedures. 
••EXPLOSION OF TIRE/RIM ASSEMBLY 
DUE TO IMPROPER MOUNTING. 
Only specially-trained persons should mount 
tires. When mounting tires, use safety cage 
and clip-on extension air hose to inflate.
••FAILURE TO MOUNT RADIAL TIRES ON 
APPROVED RIMS. 
••FAILURE TO DEFLATE SINGLE OR DUAL 
ASSEMBLIES COMPLETELY BEFORE 
DEMOUNTING. 
••TIRE SPINNING. 
On slippery surfaces such as snow, mud, ice, 
etc., do not spin tires in excess of 35 mph 
(55 kph), as indicated on the speedometer. 
••EXCESSIVE WHEEL SPINNING. 
This can also result in tire disintegration or 
axle failure.
WARNING: Vehicle handling, traction, ride 
comfort and other performance parameters 
may be significantly affected by a change in 
tire size or type. Before replacing tires, always 
consult and follow the vehicle Owner’s Manual 
because some vehicle manufacturers prohibit 
changing tire size. When selecting tires that 
are different from the original equipment size 
make certain: (1) The tires have adequate 
load carrying capacity based on the vehicle 
placard, (2) The tires have sufficient inflation 
pressure to carry the load and (3) There is 
proper clearance with no interference points 
between the tire and vehicle. The consumer 
must be aware to always drive safely and obey 
all traffic laws. Avoid sudden, sharp turns or

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. 
When replacing tires, you must maintain the 
outside diameter and load carrying capacity of 
the Original Equipment tire. Inflation pressure 
may need to be adjusted to avoid overloading 
the tire. Consult the Tire & Rim Association 
Load and Inflation Tables, ETRTO or JATMA 
standards for correct load and inflation 
information.
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 
originally equipped 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 vehicle, they should 
be installed with like pairs on the same axle. 
The speed capability of the vehicle will become 
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 consult Dealer 
for optimum rim width and carefully check 
vehicle/tire clearances.

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 
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.

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.
