For U.S.A.The following information has been
compiled according to Code of
Federal Regulations“Title 49, Part
575”.
Tire information&Tire labelingMany 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 sizeYour 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
7section 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.
