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, including spare tire, degrade over time with
age even when they are not being used. It is recom-
mended that tires over 6 years generally be replaced
even if damage is not obvious.

Cord: the strands forming the plies in the tire.

Rim: a metal support for a tire or a tire and tube assembly
upon which the tire beads are seated.

Rim diameter: nominal diameter of the bead seat.

Groove: the space between two adjacent tread ribs.Tire Markings
Size Designation
EXAMPLE:P215/65R15

NOTE

European/Japanese metric tire sizing is based on
European/Japanese design standards. Tires designed
to these standards have the tire size molded into the
sidewall beginning with the section width. The letter
“P” is absent from this tire size designation. Exam-
ple: 215/65R15 96H.

LT (Light Truck) -metric tire sizing is based on
U.S.A. design standards. The size designation for
LT-metric tires is the same as for P-metric tires
except for the letters “LT” that are molded into the
sidewall preceding the size designation. Example:
LT235/85R16.


Temporary spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.

RConstruction code
• “R” means radial construction.
• “D” means diagonal or bias construction.

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.
Check your tires each time you refuel. If one tire looks lower
than the others, check the pressure for all of them.
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 replace the caps on
the valve stems.

CAUTION
!
A compact spare tire can be installed temporarily in
place of a tire that has been removed during the tire
rotation. However, it must not be included in the
regular tire rotation sequence.Tires that do not have arrows showing rotation direction

CAUTION
!
If the tires have arrows (A) indicating the correct
direction of rotation, swap the front and rear tires
on the left-hand side of the vehicle and the front and
rear tires on the right-hand side of the vehicle sepa-
rately. Keep each tire on its original side of the vehi-
cle. When installing the tires, make sure the arrows
point in the direction in which the wheels will turn
when the vehicle moves forward. Any tire whose
arrow points in the wrong direction will not perform
to its full potential.
