This means there will be a period of time where there will be both 2 digit and 3 digit plant codes.

To make the transition easier, NHTSA has reserved a series of 3 digits codes starting with the number "1" (One) followed by the previous 2 digit codes.

Once a tire begins to break down, it becomes more likely to fail in the form of a tread separation–often at highway speeds, when the failure is most likely to cause catastrophic injuries or death.

For most tires, this expiration date should be six years from the date of manufacture.

Please drop me a note if you have a topic you want to see: [email protected] Tire Update April 2015: NHTSA (National Highway and Traffic Safety Administration), the branch of the US government that regulates tires (and in this case, what is required to appear on the sidewall), has annouced that they have run out of 2 digit plant codes (see below) and are making a change to a 3 digit plant code.

I have updated the web page to reflect those changes.

It is NOT required that everone use this coding system, but I expect everyone to do so.
