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 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.
