DOT Code (Tyre Date Code)
The DOT code on the sidewall identifies the tyre factory and production date.
What is DOT Code (Tyre Date Code)?
The last four digits show week and year. For example 2324 means week 23 of 2024. It helps check tyre age. Tyres made before 2000 used a three-digit date code. The full DOT code may only be printed on one side of the tyre, so check both sides. Many experts recommend checking older tyres carefully and replacing them after a certain age, even with good tread.
How it works
The code is moulded into the sidewall.
Why it matters for your car
Old tyres may harden. Check the date when buying.
