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

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.
