Tire Terminology And Definitions
TermDefinition
B-Pillar The vehicle B-Pillar is the structural member of
the body located behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than 1
mile (1.6 km) after sitting for a minimum of three
hours. Inflation pressure is measured in units of
PSI (pounds per square inch) or kPa
(kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the
maximum permissible cold tire inflation pressure
for this tire. The maximum inflation pressure is
molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer’s recommended cold tire
inflation pressure as shown on the tire placard.
Tire Placard A label permanently attached to the vehicle
describing the vehicle’s loading capacity, the
original equipment tire sizes and the
recommended cold tire inflation pressures. TIRES

TIRES

Life Of Tire
The service life of a tire is dependent upon varying factors including, but
not limited to:
•˜ž›1 riving
style
ï
• Tire pressure - Improper cold tire inflation pressures can cause uneven
wear patterns to develop across the tire tread. These abnormal wear
patterns will reduce tread life, resulting in the need for earlier tire
replacement.
• ‘Ž1 –’•Žœ
driven.
• Performance tires, tires with a speed rating of V or higher, and
Summer tires typically have a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six years, regardless
of the remaining tread. Failure to follow this warning can result in
sudden tire failure. You could lose control and have a collision
resulting in serious injury or death.
TIRES
Keep
dismounted
tires
in
a
cool,
dry
place
with
as
little
exposure
to
light

as
possible.
Protect
tires
from
contact
with
oil,
grease,
and
gasoline.
Replacement Tires
The
tires
on
your
new
vehicle
provide
a
balance
of
many
characteristics.

They
should
be
inspected
regularly
for
wear
and
correct
cold
tire

inflation
pressures.
The
manufacturer
strongly
recommends
that
you
use

tires
equivalent
to
the
originals
in
size,
quality
and
performance
when

replacement
is
needed.

The
Load
Index
and
Speed
Symbol
for

your
tire
will
be
found
on
the

tire
sidewall.
See

for

information
relating

and
Speed
Symbol
of
a
tire.
It
is
recommended
to
replace
the
two
front
tires
or
two
rear
tires
as
a
pair.

Replacing
just
one


tire
can
seriously
affect
your
vehicle’s
handling.
If
you
17

ever replace a wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized tire dealer or original
equipment dealer with any questions you may have on tire specifications
or capability. Failure to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size, load rating, or speed rating other than
that specified for your vehicle. Some combinations of unapproved
tires and wheels may change suspension dimensions and perfor-
mance characteristics, resulting in changes to steering, handling,
and braking of your vehicle. This can cause unpredictable han-
dling and stress to steering and suspension components. You could
lose control and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with load ratings approved
for your vehicle.
• Never use a tire with a smaller load index or capacity, other than
what was originally equipped on your vehicle. Using a tire with a
smaller load index could result in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires having adequate speed
capability can result in sudden tire failure and loss of vehicle
control.
CAUTION!
Replacing original tires with tires of a different size may result in
false speedometer and odometer readings.
