How to Use the Tire Date Decoder
Decode your tire's DOT code to find out exactly when it was manufactured and if it is still safe to drive on.
Steps
- Locate the DOT code on your tire's sidewall. It usually starts with "DOT".
- Find the final 4 digits of this code (e.g., 3519).
- Enter these 4 digits into the input box.
- Instantly view your tire's exact age, manufacture date, and a safety recommendation.
About This Tool
Tire DOT date codes follow a strict format: the first two digits represent the week of the year, and the last two digits represent the year (e.g., 3519 means the 35th week of 2019). This tool calculates the exact age from the current date and applies industry safety guidelines.
FAQs
1. How long do tires last?
Industry guidelines state tires up to 5 years old are generally safe. Between 6-10 years, they should be used with caution and inspected regularly. Any tire over 10 years old must be replaced, regardless of tread wear.
2. Why does my tire only have a 3-digit code?
Tires manufactured before the year 2000 used a 3-digit code. If your tire has a 3-digit code, it is more than two decades old and is extremely unsafe to drive on.
3. Where can I find the DOT code?
Look at the sidewall of your tire near the rim. If you only see letters but no 4-digit number, check the sidewall on the inside (underneath the car).
