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 aggressive 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) inspection for proper inflation, even tread wear 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. Check inflation pressures at least once a month
and before long trips. Use an accurate tire pressure gauge. Always check
GOODYEAR DUNLOP TIRES

is important for proper tire load distribution and function. The maximum
load capacity stamped on the sidewalls of P-Metric & European Metric
tires is reduced by 10% when used on a light truck, utility vehicle or
trailer. Never fit P-Metric or European Metric tires to light trucks that
specify LT-type replacement tires.
DON’T SPIN YOUR TIRES EXCESSIVELY
Avoid excessive tire spinning when your vehicle is stuck in snow, ice,
mud or sand. The centrifugal forces generated by a free-spinning
tire/wheel assembly may cause sudden tire explosion, resulting in
vehicle damage and/or serious personal injury to you or a bystander.
Never exceed 35 mph / 55 kph, as indicated on your speedometer. Use a
gentle backward and forward rocking motion to free your vehicle for
continued driving. Never stand near or behind a tire spinning at high
speeds, for example, while attempting to push a vehicle that is stuck or
when an on-the-car spin balance machine is in use.
DO CHECK YOUR TIRES FOR WEAR
Always remove tires from service when they reach two thirty-seconds of
an inch (2/32) remaining tread depth. All new tires have tread wear
indicators which appear as smooth banks in the tread grooves when they
wear to the two thirty seconds of an inch (2/32) level. Many wet weather
accidents result from skidding on bald or nearly bald 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 Dealer 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 does 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 manufac-
turers and to Goodyear ’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 recommends 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 from the Original Equipment size, see a professional
installer in order to make certain that proper clearance, load-
carrying capacity and inflation pressure are 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 aggressive 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 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.
GOODYEAR DUNLOP TIRES

For all types of tires, consult your vehicle tire placard or owner ’s manual
for recommended operating pressures. If the tires are purchased as
replacement tires, operating instructions for the low pressure warning
system will be provided by the manufacturer of that system. Recom-
mended operating pressures will be provided by a participating Michelin
tire retailer for self supporting ZP tires. Recommended operating pres-
sure for PAX System Tires will be provided by a PAX System retailer.
These inflation pressures must be maintained as a minimum. However,
do not exceed the maximum pressure rating indicated on the tire
sidewall.
CHECK THE COLD INFLATION PRESSURES IN ALL YOUR TIRES,
INCLUDING THE SPARE, AT LEAST ONCE EACH MONTH
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 each month and
always prior to long distance trips. This applies to all tires, including
sealant types, and Self-Supporting Zero Pressure (ZP) tires which are as
susceptible to losing air pressure as any other type of tire if not properly
maintained.
UNDERINFLATION
It is impossible to determine whether tires are properly inflated by
simply looking at them. It is almost impossible to “feel or hear” when a
tire is being run underinflated or nearly flat. Tires must be checked
monthly with a tire pressure gauge.
Pressures should be checked when tires are cold, in other words, before
they have been driven on. Driving, even for a short distance, causes tires
to heat up and air pressure to increase.
Checking pressure when tires are hot:
If pressures are checked after tires have been driven for more than three
minutes or more than one mile, (2 km) the tires become hot and the
pressures will increase by approximately 4 psi. Therefore when the tire
pressure is adjusted under these conditions, it should be increased to a
gauge reading of 4 psi greater than the recommended cold inflation
pressure.

HIGH SPEED DRIVING CAN BE DANGEROUS
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, has a greater
chance of causing tire damage than at a 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 the spare at once and visit a participating
Michelin Tire Retailer.
Exceeding the maximum speeds shown on the following page for each
type of MICHELIN® tire 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 when one or more tires
experience a 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 RATINGS
Speed Symbols are shown on the sidewall of some MICHELIN® tires.
The following table shows the maximum speed corresponding to the
symbol.
*Some V (or VR) rated tires may have a speed capacity greater than
149 mph (240 km/h). Consult your participating Michelin® tire retailer
for maximum speed rating if your vehicle capability exceeds this speed.
**Z (or ZR) rated tires are designed to use on cars with maximum speed
capabilities in excess of 149 mph (240 km/h).
(W and Y speed ratings are subcategories of Z).
Consult your Michelin tire retailer for maximum speed capabilities. For
PAX® System Tires consult an authorized PAX System Tire Retailer.
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.
MICHELIN

DO NOT OVERLOAD - DRIVING ON ANY OVERLOADED TIRE IS
DANGEROUS
The maximum load rating of your tires is molded on the tire sidewall. Do
not exceed this rating. Follow the loading instructions of the manufac-
turer of your vehicle and this will ensure that your tires are not
overloaded. Tires which are loaded beyond their maximum allowable
loads for the particular application will build up excessive heat that may
result in sudden tire destruction.
Do not exceed the gross axle weight rating for any axle on your vehicle.
TRAILER TOWING
If you anticipate towing a trailer, you should visit any Michelin tire
retailer for advice concerning the correct size tire and pressures. Tire size
and pressures will depend upon the type and size of trailer and hitch
utilized, but in no case must the maximum cold inflation pressure or tire
load rating be exceeded. Check the tire decal and the owner ’s manual
supplied by the manufacturer of your vehicle for further recommenda-
tions on trailer towing.
MICHELIN® PAX® System Tires/Self-Supporting Zero Pressure (ZP)
Tires and Trailer Towing
Operation of Pax or ZP tires at low or zero air pressure with a trailer in
tow, is dangerous and is not recommended. If the low pressure warning
indicator is activated when a trailer is in tow, stop, disconnect the trailer,
and do not continue to tow the trailer until the tire has been repaired and
re-inflated to the proper air pressure. If the tire cannot be repaired, it must
be replaced with a new full size, PAX/ZP tire, and inflated to the proper
air pressure, before the trailer can be safely towed again.
WHEEL ALIGNMENT AND BALANCING ARE IMPORTANT FOR
SAFETY AND MAXIMUM MILEAGE FROM YOUR TIRES.
CHECK HOW YOUR TIRES ARE WEARING AT LEAST ONCE EACH
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
MICHELIN
176
checked immediately. Tires which have been run underinflated will show
more wear on the shoulders than in the center of the tread.
TIRE MIXING
MICHELIN® tires are radial tires and for best performance it is recom-
mended that the same size and type of tire be used on all four wheel
positions. Before mixing tires of different types in any configuration on
any vehicle, be sure to check the vehicle manufacturer ’s owner‘s manual
for its recommendations.
It is especially important to check the vehicle manufacturer ’s owner ’s
manual when mixing, matching, or replacing tires on 4-wheel drive
vehicles, as this may require special precautions.
MICHELIN DOES NOT RECOMMEND MIXING PAX® SYSTEM TIRES
WITH NON-PAX TIRES / SELF-SUPPORTING ZERO PRESSURE (ZP)
TIRES WITH NON-ZP TIRES OTHER THAN THE TEMPORARY USE
OF THE SPARE IF THE VEHICLE IS SO EQUIPPED.
WINTER DRIVING
Tires which meet the Rubber Manufactures Association (RMA) definition
of snow tires are marked M/S, or M&S. On such tires, this designation is
molded into the sidewall. Tires without this notation are not recom-
mended or winter driving.
While All-Season tires are designed to provide reliable
performance in some winter conditions, the use of four
(4) winter tires is recommended for optimal performance.
Tires designate for use in severe winter conditions are
marked on at leas one sidewall with the letter “M”
TIRE ROTATION AND REPLACEMENT
To obtain maximum tire wear, it may be necessary to rotate your tires.
Refer to your vehicle owner ’s manual for instructions on tire rotation. If
you do not have an owner‘s manual for your vehicle, Michelin recom-
mends rotating your tires every 6,000 to 8,000 miles (10,000 to 12,000 km).
Monthly inspection for tire wear is recommended. Your tires should be
rotated at the first sign of irregular wear, even if it occurs before 6,000
miles (10,000 km). This is true for all vehicles.
