Safety precautions

WARNING

Bulbs may become very hot while
illuminated. Before replacing bulbs,
turn off the lights and wait until the
bulbs cool down. Otherwise, there is
a risk of sustaining a burn injury.

CAUTION

Replace any bulb only with a new
bulb of the specified wattage. Using
a bulb of different wattage could
result in a fire.

Tire information

&

Tire labeling

Many markings (e.g. Tire size, Tire
Identification Number or TIN) are
placed on the sidewall of a tire by
tire manufacturers. These markings
can provide you with useful infor-
mation on the tire.

!

Tire size

Your vehicle comes equipped with
P-Metric tire size. It is important to
understand the sizing system in
selecting the proper tire for your
vehicles. Here is a brief review of
the tire sizing system with a break-
down of its individual elements.

!

P Metric

With the P-Metric system, Section
Width is measured in millimeters.
To convert millimeters into inches,
divide by 25.4. The Aspect Ratio
(Section Height divided by Section
Width) helps provide more dimen-
sional information about the tire
size.

Example:

(1)

P = Certain tire type used on

light duty vehicles such as passen-
ger cars
(2)

Section Width in millimeters

(3)

Aspect Ratio (= section height

section width).

(4)

R = Radial Construction

(5)

Rim diameter in inches

!

Load and Speed Rating
Descriptions

The load and speed rating descrip-
tions will appear following the size
designation.
They provide two important facts
about the tire. First, the number
designation is its load index. Sec-
ond, the letter designation indicates
the tire’s speed rating.

Consumer information and Reporting safety defects/For U.S.A.

13-2

(463,1)

Example:

(6)

Load Index: A numerical code

which specifies the maximum load
a tire can carry at the speed
indicated by its speed symbol, at
maximum inflation pressure.

For example, “90” means 1,323 lbs
(600 kg), “89” means 1,278 lbs (580
kg).

WARNING

Load indices apply only to the
tire, not to the vehicle. Putting
a load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire’s rated
load.

(7)

Speed Rating: An alphabetical

system describing a tire’s capability
to travel at established and prede-
termined speeds.
For example, “V” means 149 mph
(240 km/h)

WARNING

.

Speed ratings apply only to

the tire, not to the vehicle.
Putting a speed rated tire on
any vehicle does not mean
the vehicle can be operated
at the tire’s rated speed.

.

The speed rating is void if

the tires are worn out, da-
maged, repaired, retreaded,
or otherwise altered from
their original condition. If
t i r e s a r e r e p a i r e d , r e -
treaded, or otherwise al-
tered, they may not be sui-
table for original equipment
tire designed loads and
speeds.

!

Tire Identification Number
(TIN)

Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of
four groups. Here is a brief review of
the TIN with a breakdown of its

individual elements.

(1)

DOT symbol*

(2)

Manufacturer’s Identification

Mark
(3)

Tire Size Code

(4)

Tire Type Code

(5)

Date of Manufacture

The first two figures identify the
week, starting with “01” to represent
the first full week of the calendar
year; the second two figures repre-
sent the year. For example, 0101
means the 1st week of 2001.
*: The DOT symbol certifies that the

tire conforms to applicable Fed-
eral Motor Vehicle Safety Stan-
dards.

!

Other markings

The following makings are also
placed on the sidewall.

– CONTINUED –

Consumer information and Reporting safety defects/Tire information

13-3

(464,1)

!

Maximum permissible infla-
tion pressure

The maximum cold inflation pres-
sure to which this tire may be
inflated. For example, “300 kPa
(44 PSI) MAX. PRESS”

!

Maximum load rating

The load rating at the maximum
permissible weight load for this tire.
For example, “MAX. LOAD 580 kg
(1,279 LBS) @ 300 kPa (44 PSI)
MAX. PRESS.”

WARNING

Maximum load rating applies
only to the tire, not to the
vehicle. Putting a load rated
tire on any vehicle does not
mean the vehicle can be
loaded up to the tire’s rated
load.

!

Construction type

Applicable construction of this tire.
For example, “TUBELESS STEEL
BELTED RADIAL”

!

Construction

The generic name of each cord
material used in the plies (both
sidewall and tread area) of this tire.
For example, “PLIES: TREAD 2
STEEL + 2 POLYESTER SIDE-
WALL 2 POLYESTER”

Vehicle placard

The vehicle placard is attached to
the driver’s side door pillar.

Example:

Consumer information and Reporting safety defects/Tire information

13-4

(465,1)

The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.

!

Adverse safety conse-
quences of under-inflation

Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of
vehicle control could lead to an
accident.

!

Measuring and adjusting air
pressure to achieve proper
inflation

Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to

adjust the tire pressures to the
specific values. Driving even a short
distance warms up the tires and
increases the tire pressures. Also,
the tire pressures are affected by
the outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle. When a tire
becomes warm, the air inside it
expands, causing the tire pressure
to increase. Be careful not to mis-
takenly release air from a warm tire
to reduce its pressure.
