How to Determine the Age of BF Goodrich Tires

BF Goodrich tires conform to the U.S. Department of Transportation standards for displaying the manufacturing date. The standard form displays the date of manufacture by week and year. It's important to know the age of your tires because tires can crack with age, not just with mileage.

Step 1

Look for the letters "DOT" to find the Department of Transportation number on the tire sidewall. The DOT tag indicates that the tire meets all federal standards.

Step 2

Find the four numbers at the end of the code.

Step 3

Look at the last two numbers to determine the year of manufacture. For example, if the DOT code ends in "2807," the "07" indicates that tire was made in 2007.

Step 4

Look at the two numbers right before the numbers indicating the year to determine the week of manufacture. For example, if the DOT code ends in "2807," the "28" indicates that the tire was made in the 28th week of 2007.

Look at a calendar for the year and count the number of weeks to determine when your tire was made. In 2007, for example, the 28th week was July 8 to 14.


  • BF Goodrich recommends that your tires be inspected annually if they are more than five years old.


  • If the DOT code ends in three numbers, the tire was made before 2000 and should probably be replaced. BF Goodrich recommends that tires that are at least 10 years old be replaced even if they have not worn down.
