Locate The Tire Information

Look at the driver’s side door. Open the door and find a sticker. The sticker has the tire size listed. It may be on the door frame or the door itself. The numbers on the sticker show the tire size. This helps you see what tires fit your car.
Read The Tire Sidewall
Tires have many numbers and letters on the side. These are important. The tire sidewall shows the size code. Find the code on the tire’s edge.
Identify The Code
The code looks like this: P215/65R15. The first part (P) means passenger car. The next numbers (215) show the tire’s width in millimeters.
Understand The Measurements
The number after the slash (65) is the aspect ratio. It tells the height compared to the width. The letter R means it is a radial tire. The last number (15) is the diameter of the wheel in inches.
Decode The Tire Code
Section Width is the first number in the tire code. This number is in millimeters. It shows the width of the tire from side to side. For example, if the code is 205/55R16, then the section width is 205 millimeters. It tells you how wide your tire is.
Aspect Ratio is the second number in the tire code. It shows the height of the tire sidewall. This number is a percentage of the section width. If the code is 205/55R16, then the aspect ratio is 55. This means the height is 55% of the width.
Construction Type is the letter after the aspect ratio. It shows how the tire is built. The most common letter is “R,” which means radial construction. This means the layers run in a circle around the tire.
Rim Diameter is the last number in the tire code. It shows the size of the wheel the tire fits on. This number is in inches. If the code is 205/55R16, then the rim diameter is 16 inches.
