Determining the Width of Your 21 Inch Tires
Knowing your vehicle's tire width (also called cross section) is an important step when shopping for tires. To determine these measurements, check the vehicle's tire information placard on the door jamb of the driver's side door. Or, check the sidewalls of your current tires. You'll see a series of numbers and symbols that look like this: P265/35 R22. The first number in the series (265) is the width of your tires. It is measured in millimeters (mm). In our example, the tire's width is 265 mm.
Finding the Height of a 21 Inch Tire
Your vehicle's tire height (also called aspect ratio) is also located on the tire information placard on the driver's side door jamb, as well as on the sidewalls of your current set of tires. In this series of numbers, which is similar to P265/35 R22, the number right after the / is the height of your tires. So, in our example the tire height would be 35.
