Most people do not know how to find the manufacturing date of a tyre. The manufacturing date of a tyre is very important for every person they know the safety and reliability of their vehicle. Tyres have a limited lifespan and can deteriorate over time. If they do not use it, it is very essential to know their age. The manufacturing date of a tyre can be found in the tyres’ DOT (Department of Transportation) code. This series consists of letters and numbers stamped on the tyre’s sidewall. The last four digital numbers represent the week and year of the tyre manufacturing. Let’s know the complete information on how to find the manufacturing date of a tyre on this web page.
DOT Code and Its Location on the Tyre
The Department of Transportation code, or DOT code, is a series of numbers and letters found on the sidewall of a tyre. The code is a collection of information mandated by the Federal Motor Vehicle Safety Standard (FMVSS) to be printed on all tyres sold worldwide. The DOT code contains information about the tyre, such as its manufacturer, manufacturing plant, size, and manufacturing date. The code is often composed of the letter “DOT” followed by a string of numbers and letters. The DOT code is situated on the sidewall of the tyre, close to the bead, and differs depending on the tyre manufacturer (the edge of the tyre that sits on the rim). It is crucial to note that the DOT code may be difficult to read and may necessitate rigorous inspection.
How to Find the Manufacturing Date of a Tyre
How to Use MMDD Code
The “MMDD” format used in the DOT code represents the tire’s manufacturing date. In this format, the final four digits of the DOT code denote the manufacturing date, where:
- The first two numbers (MM) reflect the year’s week (01-52)
- The year is represented by the last two numbers (DD).
- For example, if the last four digits of the DOT number are “2419,” the tyre was made in the 24th week of 2019.
- It’s crucial to remember that while this format is common in the United States, other countries may use a different one.
It’s also worth noting that the week of the year is not the same as the calendar week and can be influenced by holidays and weekends; it’s better to confirm the production date with the manufacturer.
In conclusion, knowing a tyre’s manufacturing date is crucial for assuring the dependability and safety of your car. The DOT code, a string of letters and numbers stamped on the sidewall of the tyre, can be used to determine the date of manufacture. Understanding the tire’s creation date will assist you to decide when to replace them and maintain a secure and comfortable ride. To ensure optimum performance and handling, it is advised to routinely inspect your tyres for signs of wear and tear and replace them as necessary. You can be sure that your tyres are in good shape and prepared to keep you safe on the road by keeping note of the production date.
Where is the DOT code located on a tyre?
The DOT serial number can be found on the inside sidewall close to the rim of tyres.
What does the DOT code represent on a tyre?
DOT represents the Department of Transportation.
What information is contained in the last four digits of the DOT code?
A complete DOT code will always include four digits at the end. The tyre’s manufacture date is indicated by the last four digits, along with the tyre’s expiration date. The tyre must be replaced if the entire DOT code has only three digits and was produced before 2000.
How often should I check the manufacturing date of my tyres?
Every tyre has an expiration date that is six years from the day it was manufactured, as well as a birth date, which is the day it was made. The majority of automakers advise drivers to change their tyres after six years. Waiting any longer puts the integrity of the tyres at risk and is dangerous for drivers.
How does the manufacturing date of a tyre affect its warranty or guarantee?
If sold after three years from the date of manufacture, the warranty will be six years from that date or until the tread wear indications are equal to the tread wear, whichever comes first.
