A tire date code is listed on the tire sidewall to indicate a tire's production year. The tire manufacture date is listed at the end of the U.S. Department of Transportation's safety code on the tire sidewall. The date code first lists the week the tire was manufactured and is followed by a number representing the year it was made. For instance, if it's labeled "0301" as shown in the graphic above, that means the tire was mass-produced during the third week of 2001. However, a tire made before 2000 usually features just one digit representing the year, meaning, for example, the number nine could represent either the years 1999 or 1989.
