Tire DOT Code Information
What is a DOT Code?
The DOT Code is sometimes referred to as a serial number and is an alphanumeric code that appears on the sidewall of the tire after the letters “DOT”. This code can be found on at least one sidewall as mandated by the U.S. Department of Transportation. It identifies where and when a tire was manufactured along with other specific details about the tire. The code starts with a DOT designation followed by a series of letters and numbers. The code always ends with at least a 4 digit number representing the week and year of manufacture. Make sure you enter each tire’s DOT Code if they are different.
