How Old Are Your Tires?

This tire was made in the 41st week of 1994.

This tire was made in the 41st week of 1994.

Here’s an interesting news report on the age of tires.

In a nutshell, ABC News is positing that your car tires have an expiration date that should be heeded, and that the “brand new” tires you just purchased at a tire store might have been sitting on the shelves for years.

There’s a cryptic numbering system at the end of the “DOT” text (pictured above). The first two digits indicate the week of the year. The next digit(s) indicate the year. In the above example, “414” tells us this tire was made in the 41st week of 1994. “2101” would tell us that the tire was made in the 21st week of 2001. Also, sometimes this number is printed only on the inside wall of the tire (facing the inside of the car), so you might have to crawl under your car to see it.

Interesting stuff.
