Determining the Width & Height of Your 21 Inch Tires
Knowing your vehicle's tire width (also called cross section) and height 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). The number after the / is the height of your tires. So, in our example the tire height would be 35.
