What's My 15 Inch Tire Width?
The best place to find your vehicle's tire width (or cross section) is the tire information placard on the inside of the driver's side door. Alternatively, you can check the sidewalls of your current tires for a series of numbers and symbols similar to: P215/60 R15. The width of your tires, in millimeters (mm) will be the first number in the series. In this example, the tire's width would be 215.
How to Find the Height of 15 Inch Tires
To find your vehicle's tire height (or aspect ratio), check the placard on the inside of your driver's side door or the sidewalls of your current set of tires. There, you'll see a series of numbers and symbols similar to: P215/60 R15. The number directly after the / refers to the height of your tires. In this example, the height of the tires would be 60.
The aspect ratio (AKA height), which is measured from the wheel rim to the top of the tread, is given as a percentage of the tire's width. In the example above, the 15-inch tires would have a sidewall height that is 60% of the tread width. 60% of 215mm is 129mm. Converted to inches, this 15-inch tire has an 8.46-inch tread wide and 5.08-inch sidewall height.
