Tire width is measured in millimeters from sidewall to sidewall at the tire's widest point when properly inflated and mounted on a wheel. The tire size marking on the sidewall will indicate the tire width.
Here's a breakdown of how to find and interpret the tire width:
-
Locate the Tire Size on the Sidewall: Look for a series of letters and numbers embossed on the tire's sidewall. This will be the complete tire size designation. An example is: P215/65 R15.
-
Identify the Width: The first number in the tire size represents the tire width in millimeters. In the example P215/65 R15, the '215' indicates the tire width is 215 millimeters.
-
Understanding the Measurement: The width is the distance from one sidewall to the opposite sidewall at the tire's widest point when it is inflated and mounted on the correct rim size.
Example:
If a tire size is P205/55R16, the tire width is 205 millimeters.
It's important to note that the actual width of the tire can vary slightly depending on the manufacturer and the specific rim width on which the tire is mounted.
