    Decipher DOT tire code

    What does this DOT tire code read? This is exactly how it is on the sidewall. DOT A N U U N X 7 1 0406. The 0406 have a circle around each individual number. Google shows the last 4 digits are in an oval. BF Goodrich P225/70R15 100S. Thank you for help in advance!

    Well, the 0406 means fourth week of calendar year 2006. Don't know what the letters signify. Hope that helps a bit.

      Re: Decipher DOT tire code

      I'm not familiar with BF Goodrich but suspect they are the codes for the plant, manufacturer and tire rating. What is most important is that date code that both you and Dupere have deciphered...2006! And here it is 2019 which means a quite dated tire. Today, the lifecycle of tires is six years but I suspect most of us stretch that lifecycle. Here's an article about Corvette tires some time ago. It targets Good Years but offers some insights into tire coding.
