It is important to familiarize yourself with the following terms:

Cold tire pressure:
• The measured pressure after the vehicle has been parked
for at least three hours,
or
• The measured pressure when the vehicle is driven less
than 1 mile (1.6 km) after having been parked for three
hours.

Maximum inflation pressure: the maximum permissible
cold tire inflation pressure for this tire.

Recommended inflation pressure: the inflation pressure
for optimum tire performance.
Intended outboard sidewall:
• The sidewall that contains a whitewall, bears white let-
tering or bears manufacturer, brand, and/or model name
molding that is higher or deeper than the same molding
on the other sidewall of the tire,
or
• The outward facing sidewall of an asymmetrical tire that
has a particular side that must always face outward
when mounted on a vehicle.

Passenger car tire: a tire intended for use on passenger
cars, multipurpose passenger vehicles, and trucks, that
have a gross vehicle weight rating (GVWR) of 10,000
pounds or less.

Light truck (LT) tire: a tire designated by its manufacturer
as primarily intended for use on lightweight trucks or mul-
tipurpose passenger vehicles.

Tread: portion of a tire that comes into contact with the
road.

Tread rib: a tread section running circumferentially
around a tire.

Tread separation: pulling away of the tread from the tire
carcass.

Carcass: the tire structure, except tread and sidewall rub-
ber which, when inflated, bears the load.

Sidewall: portion of a tire between the tread and bead.

Section width: the linear distance between the exteriors of
the sidewalls of an inflated tire, excluding elevations due
to labeling, decoration, or protective bands.

Bead: the part of the tire that is made of steel wires,
wrapped or reinforced by ply cords and that is shaped to
fit the rim.

Ply: a layer of rubber-coated parallel cords.

!
Driving with tires that are worn, damaged or
improperly inflated is dangerous.
These type tire conditions will adversely affect vehi-
cle performance.
These type tire conditions can also cause a tread sep-
aration or blowout which may result in an accident
causing serious injury or death.
Tires degrade over time with age even when they are
not being used. It is recommended that tires over 6
years generally be replaced even if damage is not
obvious.

Service DescriptionEXAMPLE: 95H
Maximum Load
Maximum load indicates the maximum load this tire is
designed to carry.Maximum Pressure
Maximum Pressure indicates the maximum permissible
cold tire inflation pressure for this tire.
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire but
the date code may only be on one side. Look for the TIN
on the outboard side of tires as mounted on the vehicle. If
the TIN is not found on the outboard side then you will
find it on the inboard side of the tire.
EXAMPLE: DOT MA L9 ABCD 1504

95Load index
A numerical code associated with the maxi-
mum load a tire can carry.
HSpeed symbol
A symbol indicating the range of speeds at
which a tire can carry a load corresponding to
its load index under certain operating condi-
tions.
The maximum speed corresponding to the
speed symbol should only be achieved under
specified operating conditions. (i.e. tire pres-
sure, vehicle loading, road conditions and
posted speed limits)
WA R N I N G
!
Overloading of your tire is dangerous. Over-
loading can cause tire failure, affect vehicle
handling, and increase your stopping distance.
Use tires of the recommended load capacity for
your vehicle. Never overload them.
DOTDepartment of Transportation
This symbol certifies that the tire is in compli-
ance with the U.S. Department of Transporta-
tion tire safety standards, and is approved for
highway use.

Treadwear, Traction and Temperature GradesTreadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded
150 would wear one and one-half (1
1/2) times as well on the
government course as a tire graded 100. The relative perfor-
mance of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to
variations in driving habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and
C. Those grades represent the tire’s ability to stop on wet pave-
ment as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature
The temperature grades are A (the highest), B and C, represent-
ing the tire’s resistance to the generation of heat and its ability
to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the
minimum required by law.
Tire inflation pressures
N00939300860
Proper tire inflation pressure is essential for the safe and satis-
factory operation of your vehicle. The wrong tire pressure will
cause problems in three major areas:

Safety
Too little pressure increases flexing in the tire and can
cause tire failure. Too much pressure can cause a tire to
lose its ability to cushion shock. Objects on the road and
potholes could then cause tire damage that may result in
tire failure.

Economy
The wrong tire pressure can cause uneven wear patterns in
the tire tread. These abnormal wear patterns will reduce
the tread life, and the tire will have to be replaced sooner.
Too little pressure also makes it harder for the tire to roll,
and this uses up more power.

Ride comfort and vehicle stability
The superior riding experience built into your vehicle
partly depends on the correct tire pressure. Too much
pressure gives an uncomfortable and jarring ride. Too lit-
tle pressure feels as if your vehicle is slow to respond.
Unequal tire pressures can make steering your vehicle
uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the plac-
ard attached to the sill of the driver’s door.
(Refer to “Tire and loading information placard” on page 9-4.)

The recommended inflation pressures should be used for the
tires listed below.
Tire pressures should be checked, and adjusted if necessary, at
least once a month.
Pressures should be checked more often whenever weather
temperatures change severely, because tire pressures change
with outdoor temperatures. The pressures listed on the placard
are always “cold inflation pressure”.
Cold inflation pressure is measured after the vehicle has been
parked for at least three hours or is driven less than 1 mile
(1.6 km) after having been parked for three hours.
Cold inflation pressure must not go above the maximum values
molded into the tire sidewall. After driving several miles, your
tire inflation pressure may increase 14 to 41 KPA, 2 to 6 PSI
from the cold inflation pressure. Do not let air out of the tires to
get back to the specified cold pressure, or your tire pressure
will be too low.
You should also take the following safety precautions:

Keep your tires inflated to the recommended pressures.
(See the tire and loading information placard attached to
the sill of the driver’s door.)

Stay within the recommended load limits.

Make sure that the weight of any load in your vehicle is
evenly distributed.

Drive at safe speeds.
After filling your tires to the correct pressure, check them
for damage and air leaks. Be sure to reinstall the caps on
the valve stems.
