Locate The Dot Code
Finding the tire manufacturing date starts with locating the DOT code on the tire. This code shows important information about the tire’s origin and age.
The DOT code is a series of letters and numbers molded on the tire sidewall. It helps you determine when the tire was made.
Check The Tire Sidewall
Look around the tire’s outer edge for the DOT letters. The code usually starts with “DOT” followed by other characters.
Understand The Dot Code Format
The DOT code has many parts. The last four digits show the week and year the tire was made. For example, “2319” means the 23rd week of 2019.
- First two digits: Week of manufacture
- Last two digits: Year of manufacture
- Earlier digits: Plant and tire size code
Locate The Code On Different Tires
The DOT code may appear on one or both sides of the tire. If the inside sidewall is hard to see, check the outside sidewall for the full code.
| Position | Code Visibility |
| Outside sidewall | Usually visible |
| Inside sidewall | Sometimes hidden |
Read The Last Four Digits
Every tire has a code that shows when it was made. This code helps you know if the tire is safe to use. The last four digits on the tire sidewall tell the week and year it was made.
Knowing the tire’s age helps you avoid using old tires. Old tires can be dangerous because rubber breaks down over time.
Week Of Manufacture
The first two digits of the last four numbers show the week the tire was made. This number is between 01 and 52. It tells the exact week in the year when the tire left the factory.
- If the digits are 03, the tire was made in the 3rd week of the year.
- If the digits are 25, it was made in the 25th week.
- This helps track tire age in months.
Year Of Manufacture
The last two digits tell the year the tire was made. For example, 19 means 2019. This helps you know how old the tire is in years.
- 19 means the tire was made in 2019.
- 21 means the tire was made in 2021.
- Always check the year to avoid using old tires.
Check Tire Sidewall Details
The tire sidewall holds important information about the tire. One key detail is the manufacturing date. This date helps you know how old the tire is.
Finding the tire manufacturing date is simple if you know where to look. It is part of the tire’s sidewall codes.
Additional Date Codes
Besides the main date code, tires may have extra codes. These can give more details about when and where the tire was made.
- DOT code shows factory and batch information
- Last four digits of DOT code show week and year
- Other markings may show production shifts or inspections
Look for a group of letters and numbers starting with “DOT.” The last four numbers tell the tire’s age.
Tire Model And Size
The sidewall also shows the tire model and size. This helps you confirm the tire fits your vehicle.
| Code | Meaning |
|---|---|
| Model Name | Identifies the tire’s design |
| Size Numbers (e.g., 205/55R16) | Shows width, aspect ratio, and rim diameter |
| Load Index and Speed Rating | Indicates maximum load and speed |
Check all these details to make sure you get the right tire and know its age.

Understand Tire Age Importance
Tires have a limited lifespan that affects safety and performance. Knowing the tire manufacturing date helps you decide when to replace them.
Older tires can become unsafe even if they look fine. Always check the date code before buying or using tires.
Safety Considerations
Tires degrade over time due to heat, sunlight, and weather. This makes them weaker and more likely to fail.
- Check the tire’s DOT code to find the manufacturing week and year.
- Replace tires that are over six years old, even if the tread looks good.
- Older tires may crack, causing air leaks or blowouts.
- Unsafe tires increase the risk of accidents and injuries.
Performance Impact
Tire age affects grip, handling, and braking. Old tires lose their ability to perform well on wet or slippery roads.
| Age | Performance Impact |
| Less than 3 years | Optimal grip and handling |
| 3 to 6 years | Reduced traction, slight stiffness |
| Over 6 years | Significant loss of grip and flexibility |
