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 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. 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.*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.
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
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 and Dunlop do 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 manufacturers and to Goodyear
and Dunlop’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.
