How do I tell the age of a tyre?
Determining the age of your tyre
Each tyre has a manufacture date stamped on its sidewall, which allows you to determine its age.
Understanding the DOT code
On the sidewall of the tyre, find the DOT code. The last four digits of the code indicate the week and year the tyres were manufactured:
- 2523 indicates the tyre was produced in week 25 of the year 2023
- 0921 indicates the tyre was produced in week 9 of the year 2021
The DOT code is usually located on one side of the tyre by the rim. You may have to look on both sides of the tyre, as it may be printed on the side that is facing inward.
Tyres that show three digits should be replaced regardless of tread depth because they were manufactured before the year 2000.
Why age matters
Rubber naturally deteriorates over time. Most manufacturers suggest changing tyres after 5 to 6 years, and tyres should never be used for more than 10 years since their date of manufacture.
