How old are my tires?
How to find the DOT code?
Each tire has an imprinted DOT code. The four-digit DOT code is usually located in a window on the tire sidewall.
M5EJ 006X - wrong Do not use codes with letters! You need only the numbers.
3811 - proper Find the 4 digit number, 3811 in this example.
- The first two digits of the code represent the week of production during the year (from 1 to 52).
- The second two digits represent the year of manufacture.
- If your DOT code is a 3-digit number, it means your tire was produced before 2000.
Tire aging and road safety
Using the old, worn-out tires carry an increased risk of accident on the road.
- If your tires are older than 5 years, you should 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).
