The chronological age of any tire can be found on the tire sidewall by examining the characters following the symbol "DOT".

The last four numbers identify the date of manufacture of the tire to the nearest week.

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

All Kumho tires are manufactured to a rigid set of manufacturing standards.

The first 2 or 3 digits are a code for the manufacturing plant.

Prior to April of 2015, all plant codes were 2 digits, but after April of 2015, a third digit was permissible, and 3 digits are required by April of 2025.

We recommend: All tires (including spare tires) that were manufactured more than ten years ago should be replaced with new tires, even if they appear to be usable from their external appearance and if the tread depth may have not reached the minimum wear out depth.

To find the correct pressure for your tires, look at the tire information placard that’s mounted inside the frame of the driver’s door, in the glove box or inside the fuel door.

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.

The first two of these four numbers identify the week of manufacture (which range from "01" to "53").

The last two numbers identify the year of manufacture (e.g., a tire with the information "DOT XXXXXXX2714” was manufactured in the 27th week of 2014).

This is because tires are made mostly of rubber, and rubber degrades with age.
