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) es-
tablished 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 AP-
PROVED RIMS.
FAILURE TO DEFLATE SINGLE OR DUAL AS-
SEMBLIES COMPLETELY BEFORE DE-
MOUNTING.
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 af-
fected 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 clear-
ance 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 lane changes. Failure to follow any of these warnings
may result in loss of control of the vehicle, leading to an
accident and serious injury or death.
TIRE CARE AND MAINTENANCE GUIDE
The easiest way to help ensure satisfactory mileage and
performance from your Goodyear or Dunlop tires is to
give them a simple but frequent (at least monthly) in-
spection for proper inflation, even treadwear, and the
presence of any damage.
DO MAINTAIN PROPER INFLATION
PRESSURE IN YOUR TIRES
Proper inflation pressure is necessary for optimum tire
performance, safety and fuel economy. To maintain
proper inflation pressure, frequently (at least monthly)
check tires (when they are cool) with an accurate tire
pressure gauge.*
For example, it is difficult to tell just by looking at radial
tires whether they are underinflated.
Furthermore, when operating a vehicle equipped with
radial tires, it is difficult to notice when a tire has gone
flat or nearly flat since the “feel” of the vehicle does not
change significantly.
*Evidence of air loss or repeated underinflation
always requires expert inspection to determine
the source of leakage and tire removal to deter-
mine repairability. To avoid injury, NEVER attempt to
reinflate a tire that has been run severely underinflated.
Progressive air loss may result from punctures, cuts,
curbing, impacts or partial bead unseating. Some fit-
ment causes for air loss are (1) incomplete bead seat-
ing, (2) bead tearing caused by a machine tool due to
insufficient lubrication or improper adjustment, (3) leak-
ing valve core or rubber valve components. These
should be replaced when problems are detected and
whenever tires are replaced.

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 align-
ment or balance. These conditions not only shorten the
life of your tires, but adversely affect the handling char-
acteristics of your vehicle which could be dangerous. If
you detect irregular wear or vibration, have your align-
ment 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 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 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 exces-
sive wheel spin. In such conditions, with automatictransmission vehicles, by accelerating the engine ex-
cessively, 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 thin-
ner 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 inspec-
tion 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 preferredthat all four tires are the same construction type (i.e.,
High Performance, All Season, Mud & Snow) and con-
struction (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 recommen-
dations.
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 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 informa-
tion on tire replacement precautions.
TIRE ROTATION
Tires on your Nissan 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
