DOT Code

The DOT code is a series of characters stamped on the tyre sidewall by the manufacturer, mandated by the US Department of Transportation. The last four digits indicate the week and year of manufacture — for example, 2524 means the tyre was made in week 25 of 2024. The DOT code is important for identifying tyre age, as rubber degrades over time regardless of use. Most manufacturers recommend replacing tyres over 10 years old, and many commercial fleet policies set a lower age limit of 5-7 years.
