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 marking can
provide you with useful information on the tire.
! Tire size
Your vehicle comes equipped with P-Metric tire
size. It is important to understand the sizing sys-
tem in selecting the proper tire for your vehicles.
Here is a brief review of the tire sizing system
with a breakdown of its individual elements.
" P Metric
With the P-Metric system, Section Width is mea-
sured in millimeters. To convert millimeters into
inches, divide by 25.4. The Aspect Ratio (Sec-
tion Height divided by Section Width) helps pro-
vide more dimensional information about the tire
size.
Example:
(1) P = Certain tire type used on light duty vehi-
cles such as passenger cars
(2) Section Width in millimeters
(3) Aspect Ratio (= section height ÷ section
width).
(4) R = Radial Construction
(5) Rim diameter in inches
(6) ZR = Speed category above 149 mph (240
km/h)

pear following the size designation.
