What do the numbers on a tire mean? The DOT number appears on the sidewall of all tires intended for sales in the U.S., and designates the location of manufacture, the week and year of production, and the specific tire.
The first three numbers in a typical size (225/45R17) are the tire's indicated section width in millimeters, measured from sidewall to sidewall. If you are familiar with measurements in inches, the section width in millimeters can be converted into inches by dividing it by 25.4. For example: 225mm / 25.4 = 8.86.
