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
pressures when the tires are cold (when the
vehicle has been driven less than one mile). If
you must check inflation when the tires are
hot, add 4 psi (27 kPa) to the recommended
cold inflation pressure. 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.
Progressive air loss may result from punctures,
cuts, curbing, impacts or partial bead
unseating. Some fitment causes for air loss are
(1) incomplete bead seating, (2) bead tearing
caused by a machine tool due to insufficient
lubrication or improper adjustment, (3) leaking
valve core or rubber valve components should
be replaced when problems are detected and
whenever tires are replaced.
Always maintain inflation pressure at the level
recommended by the vehicle manufacturer as shown on the vehicle placard, vehicle
certification label or in the vehicle Owner’s
Manual:
Underinflation is the leading cause of tire
failure and may result in severe cracking,
component separation or “blowout.” It reduces
tire load capacity, allows excessive sidewall
flexing and increases rolling resistance,
resulting in heat and mechanical damage.
Maintaining proper inflation pressure is the
single most important thing you can do to
promote tire durability and maximize tread life.
Overinflation increases stiffness, which may
deteriorate ride and generate unwanted
vibration. Overinflation also increases the
chances of impact damage.
DON’T OVERLOAD YOUR VEHICLE
OR TIRES
Check your vehicle Owner’s Manual to
determine the load limits. Overloading your
vehicle places stress on your tires and other
critical vehicle components. Overloading a
vehicle can cause poor handling, increased
fuel consumption and may cause tire failure.
Overloading your tires can result in severe
cracking, component separation or "blowout".
Never fit your vehicle with new tires that have
less load capacity than shown on the vehicle
tire placard and remember that optimum
rim width 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 km/h, 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 treadwear 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

(Continued on next page)* Evidence of air loss or repeated underinflation always requires expert inspection to determine the source of leakage and tire removal to determine repairability. To avoid injury, NEVER attempt to
reinflate a tire that has been run severely underinflated.

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.
FOLLOW THESE ADDITIONAL
GUIDELINES
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.
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 Retailer
for optimum rim width and carefully check
vehicle/tire clearances.
RETREADED TIRES
Retreaded passenger and light truck tires
are not warranted by Goodyear and Dunlop
for any reason. Goodyear and Dunlop speed
ratings and U.S. Department of Transportation
test compliance certifications are voided for
retreaded tires.
DO MAINTAIN VEHICLE
SUSPENSION, 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
recommendations or at maximum intervals of
6,000 miles/10,000 km.

TIRE SERVICE LIFE
Tires are designed and built to provide many
thousands of miles of excellent service. For
maximum benefit, tires must be maintained
properly to avoid tire damage that may result
in removal from service before the tread is
worn down to minimum depth.
It is not practical to accurately predict the
service life of any specific tire in chronological
time since service conditions vary widely. The
serviceability of a tire over time is a function
