Tire Year Code Reference Chart
Quickly map the final two digits of your tire's DOT code to its exact calendar year of production.
Quick Answer
The final two digits of a DOT code represent the year. If your tire's code ends in "19" (e.g., 3419), it was built in 2019 and is now 7 years old — past the 6-year replacement threshold. If it ends in "25" (e.g., 1025), it was built in 2025 and is nearly brand new.

Formula
Calendar Year = 2000 + Last 2 Digits of DOT code
- Direct translation — "23" = 2023, "20" = 2020
- Warranty expiry = manufacture year + 6 years (most OEM and tire brand warranties)
- Absolute maximum = manufacture year + 10 years (Michelin, Continental industry standard)
- Do not confuse the year code with the week code — week comes first, year comes last
