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
GOODYEAR/DUNLOP TIRE LIMITED WARRANTY
(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.
