has a great demonstration on how you can determine your tire’s ages: Since 2000, the week and year the tire was produced has been provided by the last four digits of the Tire Identification Number with the 2 digits being used to identify the week immediately preceding the 2 digits used to identify the year.Example of a tire manufactured since 2000 with the current Tire Identification Number format: While the entire Tire Identification Number is required to be branded onto one sidewall of every tire, current regulations also require that DOT and the first digits of the Tire Identification Number must also be branded onto the opposite sidewall.Therefore, it is possible to see a Tire Identification Number that appears incomplete and requires looking at the tire’s other sidewall to find the entire Tire Identification Number The use of a partial Tire Identification Number on the one sidewall (shown above) reduces the risk of injury to the mold technician that would have to install the weekly date code on the top sidewall portion of a hot tire mold.

Determining your tire age is very important to you and your family’s safety.

I used to think, “the tread looks great, no bald or worn out spots, these things could last at least a couple more years”.

They may last another three years, but your tread has little to do with it. Tire’s are made of rubber, obviously, and when rubber gets old, it starts to dry and crack (often times from the inside out.

This process is not always visible to the naked eye.

What’s more important than the thickness of the tread is the date that the tires were manufactured.

Until last week I had no idea that the age of the tire mattered, I thought it was all in the tread and visible cracking.I also had no idea that tires have a manufacture date stamped on them.But the manufacturers don’t make it easy on you to figure this out.It turns out that tires have cryptic codes on them.Believe it or not, you can actually determine your tire’s manufacture date based on these codes.Let’s discuss pre and post 2000 tire manufacturing date stamps (if your tire is older than this as indicated by a lack of this standard, you’ll want to have it replaced immediately).
