How to find the DOT code?

The four-digit DOT code is usually located in a window on the tire sidewall.

3811 - The DOT code is a four-digit number, 3811 in this case.

The first two digits of the DOT code indicate the production week of the year (from 1 to 52).
The third and fourth digits of the DOT code indicate the year of manufacture.
If your DOT code is a 3-digit number, it means your tire was produced before 2000.

DOT M5EJ 006X - Incorrect codes. Do not use codes with letters. Find the code that consists of only numbers.

Using the old, worn-out tires carry an increased risk of accident on the road.

If your tires are more than 5 years old, consider replacing them.
Even if the tire has a lot of tread, but the tire sidewall is old, dry and has small cracks, it would be better to replace the tire with a new one.
The recommended minimum height of a tread is 3 mm (4/32˝) for summer tires and 4 mm (5/32˝) for winter tires. Legal requirements may vary depending on the country (eg. at least 1.6 mm in EU).
