How to Tell What Year a Tire Was Manufactured

Understanding the age of your tires is crucial for ensuring safety on the road. Tires have a limited lifespan, and knowing when they were manufactured can help you make informed decisions about their replacement. In this article, we will guide you through the process of reading tire date codes and understanding their significance.

What is a Tire Date Code?

The tire date code is a four-digit number that indicates when a tire was manufactured. This code is part of the Department of Transportation (DOT) number, which is found on the tire’s sidewall. The first two digits represent the week of the year, while the last two digits indicate the year of manufacture.

• Example: A tire with the date code “2519” was made in the 25th week of 2019.

How to Read the Tire Date Code

To determine the manufacturing year of your tire, follow these simple steps:

1. Locate the DOT Number:

2. Look on the sidewall of the tire for the DOT number. This is typically found on one side of the tire.

3. Identify the Date Code:

4. The date code is usually the last four digits of the DOT number. For example, if the DOT number is “DOT U2LL LMLR 2519”, the date code is “2519”.

5. Interpret the Code:

6. The first two digits (25) represent the week of the year. This means the tire was manufactured in the 25th week.
7. The last two digits (19) indicate the year, so the tire was made in 2019.

Benefits of Knowing Your Tire’s Age

Understanding the age of your tires can provide several benefits:

• Safety: Older tires can be more prone to blowouts or other failures.
• Performance: A newer tire typically offers better grip and handling.
• Legal Compliance: Some regions have laws regarding tire age, especially for commercial vehicles.
• Cost-Effectiveness: Replacing tires before they become too worn can save you money in the long run.

Common Challenges in Identifying Tire Age

While reading tire date codes is straightforward, some challenges may arise:

• Tires Without Date Codes: Some older tires may not have the DOT code, making it difficult to determine their age.
• Tires with Worn Codes: The date code may be partially worn off, making it hard to read.
• Misinterpretation: It’s easy to confuse the week and year, so double-check your reading.

Practical Tips for Tire Maintenance

To ensure your tires remain in good condition, consider these best practices:

• Regular Inspections: Check your tires monthly for signs of wear and tear.
• Maintain Proper Inflation: Under-inflated tires can wear out faster and may lead to blowouts.
• Rotate Tires: Regular rotation helps to ensure even wear.
• Store Tires Properly: If you’re not using seasonal tires, store them in a cool, dry place away from sunlight.

When to Replace Your Tires

Knowing when to replace your tires is just as important as knowing when they were manufactured. Here are some indicators:

1. Tread Depth: Use the penny test; if you can see all of Lincoln’s head, it’s time for new tires.
2. Cracks and Bulges: Inspect for any visible damage on the sidewall.
3. Vibration or Noise: Unusual vibrations while driving can indicate tire problems.
4. Age: Tires should generally be replaced every six years, regardless of tread wear.

Conclusion

Understanding how to read tire date codes empowers you to make better decisions about tire maintenance and replacement. Regularly checking your tires can enhance your safety and performance on the road. Always keep an eye on the date codes and adhere to best practices for tire care.
