DOT:
The tires are marked with the year of manufacture 4419, meaning:
The first 2 digits indicate the number of weeks the tire has been manufactured and the last 2 digits indicate the year. (The tire with number 4419 was manufactured on 28.10.2019-03.11.2019)
At what age to buy a tire?
All major tire manufacturers say a car should not exceed 10 years.
Aalux Rehvid recommends:
• Do not drive more than 3 seasons with 1 tire run, regardless of the degree of tire wear and the age of the tire at this time should not exceed 8 years.
Example:
The year is 2019 and the DOT mark on the tire is 18, then this tire could be driven until 2028, but considering the recommendation of Aalux Rehvid, this tire should no longer be placed under 2025 cars. If you buy this year, then 5 years is a perfectly normal age.
• A tire that is up to 4 years old is considered a new tire.
The most common myths:
- It is February 2020. I would like a tire with a DOT of 2020.
If we now look at where most tires are produced and in what intervals, we will not be able to offer a 2-month-old tire.
Summer tires are produced in the second half of the year to be ready and transported around the world. Winter tires will be produced again in the first half of the year to be delivered in the autumn.
2. It's December 2020 and the tire DOT 4817.
No, I don't want this summer tire because it's 4 years old when I put it down in the spring. Looking at the production week, it cannot be 4 years old since it was produced in the last weeks of 2017, and if you look at the recommendations of the tire manufacturers, you can drive this tire until 2027 (2025 recommended by Aalux Rehvid).
If the tires are stored beautifully in storage at a constant temperature and protected from the sun, the new tire is considered to be up to 4 years old.
• The tire is most devastated by the sun (the material is rubber) and then the temperature fluctuates, and so on.
What do major tire manufacturers say about tire age (DOT) and how old a tire can be used
CONTINENTAL
Together with other members of the tire and automotive industries, Continental advises that all tires (including spare tires) made more than ten years ago should be removed from service and replaced with new tires.

NOKIAN
The recommended useful life of a tyre is six years and the recommended maximum age is 10 years.
MICHELIN
If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator. This applies to spare tires as well.
