Knowing the age of your tires is crucial for maintaining your vehicle’s safety and performance. Tires naturally degrade over time, even if they haven’t been driven much. Understanding how to read the manufacturing date on your tires allows you to make informed decisions about their replacement, ensuring optimal grip, handling, and overall safety on the road.

Decoding the Tire’s Secret Code
Where to Find the Date
The tire’s manufacturing date is typically found on the sidewall, usually near the DOT (Department of Transportation) code. It’s a four-digit number that represents the week and year of manufacture.
Understanding the Code
The first two digits indicate the week of the year, while the last two digits represent the year. For example, a tire with the code “2218” was manufactured in the 22nd week of 2018.
How To Read Manufacture Date On Tires
Knowing how to read the manufacture date on your tires is crucial for ensuring your vehicle’s safety and performance. Tires degrade over time, even when not in use, and understanding their age can help you make informed decisions about when to replace them. This comprehensive guide will walk you through the process of deciphering tire date codes, explaining the significance of each element and providing tips for interpreting them accurately.
Decoding the Tire Date Code
Tire date codes are a series of four-digit numbers located on the sidewall of the tire, usually near the DOT (Department of Transportation) identification number. These codes provide valuable information about the tire’s manufacturing week and year.
Understanding the Code Structure
The tire date code follows a specific format:
- The first two digits represent the week of the year in which the tire was manufactured.
- The last two digits represent the year of manufacture.
For example, a tire date code of “2719” indicates that the tire was manufactured in the 27th week of 2019. (See Also: Are Tires Part Of State Inspection)
Example Date Codes
Here are some examples of tire date codes and their corresponding manufacturing dates:
- “0521” – 5th week of 2021
- “1218” – 12th week of 2018
- “4023” – 40th week of 2023
Interpreting Tire Age
Once you have deciphered the tire date code, you can determine the age of the tire. Keep in mind that tires are considered to be at their peak performance for the first six years after manufacture. After this period, they begin to degrade, even if they have not been used extensively.
Tire Age and Safety
Tires that are older than six years may be more susceptible to cracking, dry rot, and other forms of deterioration. These issues can compromise the tire’s structural integrity, increasing the risk of blowouts and accidents. It is generally recommended to replace tires that are older than 10 years, regardless of their tread depth.
Factors Affecting Tire Degradation
Several factors can accelerate tire aging, including:
- Exposure to sunlight and ultraviolet (UV) radiation
- Extreme temperatures
- Ozone
- Chemical exposure
- Improper storage
Checking Tire Pressure Regularly
Maintaining proper tire pressure is essential for tire longevity and safety. Underinflated tires can wear down more quickly, while overinflated tires can become brittle and more prone to punctures. It is recommended to check your tire pressure at least once a month, and before long trips. (See Also: How Often Should I Get Tires Rotated)
Importance of Proper Tire Pressure
Proper tire pressure helps to:
- Improve fuel efficiency
- Enhance handling and control
- Reduce the risk of tire blowouts
- Extend tire life
Conclusion
Understanding how to read tire date codes is a vital aspect of vehicle maintenance. By knowing the age of your tires, you can make informed decisions about their replacement and ensure your safety on the road. Remember to check your tire pressure regularly and follow the manufacturer’s recommendations for tire care and maintenance.
This guide has provided a comprehensive overview of tire date codes, their interpretation, and the importance of tire age in relation to safety and performance. By adhering to the guidelines outlined, you can help prolong the life of your tires and maintain optimal driving conditions.

What is the recommended lifespan for tires?
While tires don’t expire in the same way food does, they do degrade over time. It’s generally recommended to replace tires after six years, regardless of tread depth, to ensure optimal safety and performance.
Can I still use tires that are older than six years?
Tires older than six years should be carefully inspected by a qualified professional. Look for signs of cracking, dry rot, or uneven wear. If the tires appear to be in good condition, they may still be safe to use, but it’s best to err on the side of caution and replace them.
