Finding Your Tire's DOT Number
Examine all sides of your tires. You will notice a series of numbers and letters that might initially seem confusing.
However, this information is vital. Look for a number starting with "DOT" followed by a series of 10 to 12 characters.
This code contains information about the tire size, the manufacturing year, and the place of manufacture, as well as a unique manufacturer code.
Tires Manufactured After 2000
For tires manufactured in the year 2000 or later, the last four digits of the DOT code indicate the date of manufacture. The first two digits represent the week, and the last two digits represent the year. For example, if the DOT code ends in "0203," the tire was manufactured in the 2nd week of 2003.
Tires Manufactured Before 2000
For tires made before 2000, the date is represented by the last three digits of the DOT code. The first two digits represent the week of manufacture, and the last digit indicates the year within the decade. For example, if the code reads "229," the tire was manufactured in the 22nd week of a year ending in '9' of that decade, such as 1999.
Unfortunately, there’s no way to tell which decade you’re looking at, other than it’s before the year 2000.
