When it comes to vehicle safety, one of the most critical components to check regularly is the tires. While many of us are diligent about checking tire pressure and tread depth, another crucial aspect of tire maintenance is often overlooked: tire age. Tires have a limited lifespan, and using old tires can significantly increase the risk of a blowout or accident, even if they look fine. In this article, we’ll explore the importance of checking tire age and provide a step-by-step guide on how to do it.
Why Checking Tire Age Matters
Tires deteriorate over time, regardless of their usage. The rubber compounds in tires break down due to exposure to heat, sunlight, and oxygen, which can cause cracks, brittleness, and other damage. This degradation can lead to a loss of traction, reduced braking performance, and increased risk of a tire failure. In fact, the National Highway Traffic Safety Administration (NHTSA) estimates that tire failures are responsible for thousands of crashes every year in the United States alone.
Understanding Tire Age: What You Need to Know
In this article, we’ll delve into the details of tire age, including how to determine the age of your tires, what the tire industry’s guidelines are for tire replacement, and how to check for signs of aging. By the end of this guide, you’ll be equipped with the knowledge to ensure your tires are safe and reliable, giving you peace of mind on the road.
How to Check Tire Age: A Comprehensive Guide
Tire safety is a critical aspect of vehicle maintenance, and one of the most important factors to consider is tire age. Regardless of the tread depth or appearance, tires have a limited lifespan and can deteriorate over time, posing a significant risk to driver and passenger safety. In this article, we will provide a step-by-step guide on how to check tire age, including what to look for, where to find the information, and what it means for your vehicle’s safety.
Why is Tire Age Important?
Tires are made from a variety of materials, including rubber, synthetic rubber, and other compounds. Over time, these materials can break down, leading to cracks, brittleness, and a loss of traction. This can result in reduced braking performance, increased stopping distances, and a higher risk of tire failure, which can lead to accidents and injuries. Tire age is a critical factor in determining the safety of your vehicle, and it’s essential to check the age of your tires regularly to ensure they are safe to use.
Where to Find the Tire Age Information
The tire age information can be found on the sidewall of the tire, in the form of a Tire Identification Number (TIN). The TIN is a series of letters and numbers that provide information about the tire, including its age. The TIN is usually located on the sidewall of the tire, near the rim, and may be preceded by the letters “DOT” (Department of Transportation). (See Also: How Often Should Tesla Tires Be Rotated)
The TIN consists of several sections, including:
- Tire manufacturer’s identifier
- Tire size and type
- Tire load rating and speed rating
- Tire age information
The tire age information is represented by a four-digit number, with the first two digits indicating the week of manufacture and the last two digits indicating the year of manufacture. For example, if the TIN reads “3218,” the tire was manufactured in the 32nd week of 2018.
How to Read the Tire Age Information
To read the tire age information, follow these steps:
- Locate the TIN on the sidewall of the tire
- Find the four-digit number that represents the tire age information
- Identify the first two digits, which indicate the week of manufacture
- Identify the last two digits, which indicate the year of manufacture
- Use the following table to determine the age of the tire:
| Tire Age | Week of Manufacture | Year of Manufacture |
|---|---|---|
| Less than 6 months | 1-26 | Current year or previous year |
| 6 months to 1 year | 27-52 | Previous year |
| 1-2 years | 1-26 | Two years prior |
| 2-3 years | 27-52 | Two years prior |
| 3-4 years | 1-26 | Three years prior |
| 4-5 years | 27-52 | Three years prior |
| 5-6 years | 1-26 | Four years prior |
| More than 6 years | 27-52 | Four years prior or older |
What Does the Tire Age Mean?
Once you have determined the age of your tire, you can use the following guidelines to assess its safety:
- Tires less than 6 months old: These tires are considered new and are safe to use.
- Tires 6 months to 1 year old: These tires are still relatively new and are safe to use, but may have some minor signs of aging.
- Tires 1-2 years old: These tires are still safe to use, but may start to show signs of aging, such as minor cracks or discoloration.
- Tires 2-3 years old: These tires are approaching the end of their safe lifespan and may start to show more pronounced signs of aging, such as deeper cracks or brittleness.
- Tires 3-4 years old: These tires are considered old and may be nearing the end of their safe lifespan. They may show significant signs of aging, such as deep cracks, brittleness, or loss of traction.
- Tires more than 4 years old: These tires are considered very old and are no longer safe to use. They may be prone to sudden failure, which can lead to accidents and injuries.
What to Do if Your Tires are Old
If your tires are old, it’s essential to take action to ensure your safety on the road. Here are some steps you can take:
- Replace the tire: If your tire is more than 4 years old, it’s recommended to replace it with a new one, even if it looks fine.
- Have the tire inspected: If your tire is between 2-4 years old, have it inspected by a professional mechanic or tire technician to assess its condition.
- Monitor the tire’s condition: Keep a close eye on your tire’s condition, looking for signs of aging, such as cracks, discoloration, or loss of traction.

Frequently Asked Questions: How to Check Tire Age
How do I find the tire identification number to check the tire age?
The tire identification number, also known as the Tire Identification Number (TIN), can be found on the sidewall of your tire. It’s a series of numbers and letters that starts with “DOT” and is followed by a series of characters. This number can be used to determine the age of your tire.
What do the numbers on the tire sidewall mean?
The numbers on the tire sidewall represent the week and year the tire was manufactured. For example, if the number is “3218”, it means the tire was manufactured in the 32nd week of 2018. This information can help you determine the age of your tire.
Why is it important to check the tire age?
Checking the tire age is important because tires have a limited lifespan, regardless of tread depth or appearance. Over time, tires can deteriorate and become more prone to failure, which can lead to accidents and injuries. Checking the tire age can help you identify when it’s time to replace your tires and ensure your safety on the road. (See Also: Are Tires Made From Oil)
Can I still use my tires if they are near the end of their recommended lifespan?
It’s not recommended to use tires that are near the end of their recommended lifespan, even if they look and feel fine. Tires can deteriorate rapidly as they approach the end of their lifespan, and using them can increase the risk of a blowout or other tire failure. It’s best to replace your tires with new ones to ensure your safety on the road.
How often should I check my tire age?
It’s a good idea to check your tire age every time you rotate your tires or have them serviced. You should also check your tire age when you purchase a used vehicle or if you’re unsure of the age of your tires. Regularly checking your tire age can help you stay safe on the road and avoid potential tire-related problems.
