When purchasing tires, it is essential to consider their manufacturing date as it provides insight into their age and quality. Understanding how to identify the production date of a tire can help you make an informed decision and ensure your safety on the road. In this article, we will guide you through the process of determining the production date of a tire.

Locate the DOT Code:
The Department of Transportation (DOT) requires all tires sold in the United States to have a standardized code imprinted on them, indicating various details, including the production date. Look for the DOT code on the sidewall of the tire, typically near the rim edge.

Identify the Week and Year:
The last four digits of the DOT code represent the production date. The first two digits indicate the week of manufacture, while the last two digits denote the year. For example, if the code ends with "3018," it means the tire was manufactured in the 30th week of 2018.

Consider the Age:
Tires have a recommended lifespan of six to ten years from the date of manufacture. Even if they appear unused or have sufficient tread depth, aging can impact their performance and safety. It is advisable to avoid purchasing tires that are more than six years old unless specifically stated by the manufacturer.

Check for Other Codes:
Some manufacturers may use alternative codes or symbols to represent the production date. If you cannot find the DOT code or are unsure about its interpretation, refer to the tire's user manual or contact the manufacturer directly for clarification.

Inspect the Tires before Purchase:
Apart from the production date, it is crucial to examine the overall condition of the tires before making a purchase. Look for signs of damage, such as cracks, bulges, or uneven wear. Additionally, ensure that the tread depth meets legal requirements and matches your specific needs for driving conditions.


Determining the production date of a tire is an important step in evaluating its quality and longevity. By understanding how to locate and interpret the DOT code, you can make an informed decision when purchasing tires. Remember to consider the age of the tires and inspect them thoroughly for any signs of damage before making a final purchase. Prioritizing tire safety contributes to safer and more enjoyable driving experiences.
