Consumer information and Reporting safety defects/For U.S.A.
For U.S.A. The following information has been
compiled according to Code of
Federal Regulations “ Title 49, Part
575 ” . 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
7 section width).
(4) R = Radial Construction
(5) Rim diameter in inches
! Load and Speed Rating De-
scriptions
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.13-2

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
tires are repaired, re-
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) Manufacturer ’ s Identification
Mark
(2) Tire Size
(3) Tire Type Code
(4) 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.
! Other markings
The following makings are also
placed on the sidewall.
! 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 ”Consumer information and Reporting safety defects/Tire information

! Maximum load rating
The load rating at the maximum
permissible weight load for this tire.
For example, “ MAX. LOAD 580 kg
(1279 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 ”! Uniform Tire Quality Grading
(UTQG)
For details, refer to “ Uniform tire
quality grading standards ” F 13-14 .
& Recommended tire inflation
pressure ! Recommended cold tire infla-
tion pressure
For recommended cold tire inflation
pressure for your vehicle ’ s tires,
refer to “ Tires ” F 12-8 .
! Vehicle placard The vehicle placard is affixed to the
driver ’ s side B-pillar.Example:
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 consequences
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-13-4
