While buying tyres, it is very important to see the tyre manufacturing date. Because like everything else, tyres have an expiry date. Even if you use tyres less, you should not use them after their expiry date. Therefore, if you buy tyres of any brand, then it is important to know about the manufacturing date of the tyre at the same time. In this article, we will tell you what the manufacturing date of a tyre looks like. First of all, we need to know what the manufacturing date is.
What is the Tyre Manufacturing Date?
From the manufacturing date, you all must have understood the manufacturing date. If you do not know, we want to tell you that the manufacturing date of any product, not just tyres, is the date on which the product is made. Every company mentions this date in its product in a different way or code. Similarly, tyres also have a manufacturing date from which we can find out how old that tyre is.Â
Â
The manufacturing date of a tyre is mentioned in the sidewall of any tyre with a four-digit code. We understand it in such a way that the first two digits are the week we have to count or the last two digits are the year. For example, suppose you saw 1921 written on the sidewall of a company’s tyre. So to understand this, you will see the first two digits which are 19. It means the 19th week. Which is the first week of May. The last two words are 21 which shows the year. This means that it is the year 2021.Â
Now this code together tells that the manufacturing date of the tyre is the first week of May (dates 1 to 6) 2021. No code has the exact date, it just tells about a week, because it goes through a lot of processes so it is not possible to calculate the exact date.
Understanding the Tyre Manufacturing Date Code
Although we have told you, what is the manufacturing date of the tyre? But many times you will see here that the manufacturing date is not written directly, it is with the dot code. Let us know how you will identify it.
Example = DOT FT 8A 05VX 5018
Now to understand this
- DOT means = US Department of Transportation
- FT means = The code of the factory in which it is made or the brand’s factory. For example, if an MRF tyre is made in Noida, then this is the code of MRF’s Noida factory.
- 8A = This code to identify inside the factory, like place code, if there are 5 warehouses in a factory, then the code of each warehouse will be different.
- 05vx = This code for the place or the person, the company that makes it, who identifies in which shift, with which machine, and under which person’s supervision, it was made.
This means all the above codes are for the factory. After that comes 5018. We have told you about it in the above paragraph. In this way, you can easily understand how the manufacturing date of a tyre is identified.
One more thing to mention is that DOT means the US Department of Transportation which passes USA transportation regulations. Tires made in India have the approval of BIS.
Another thing you should know is that DOT stands for American Department of Transportation which is responsible for passing USA’s transportation regulations. Tyres made in India will have BIS (Bureau of Indian Standards) and AIS (Automotive Industry Standards) codes.
How To Identify Tyre Manufacturing Date?
For this, you should look at the sidewall of any tyre. You will see many codes and numbers on that sidewall. Look for the DOT code or BIS code among those numbers. Wherever you see DOT or BIS, you will be able to identify the manufacturing date by the methods mentioned above.Â
Some effects that reduce the life of tyres.
There are some effects that reduce the life of any tyre.
Here we would like to tell you some things from which you should protect your tyre.
1. Too much sunlight: If you drive the tyre in the sun most of the time or park your vehicle in the sun, then the rubber of the tyre starts to deteriorate.
2. Too much air: Many times we put too much air pressure in the tyre. This causes a lot of wear in the middle part of the tyre and this part becomes weak.
3. Low air: If the air pressure in the car tyre is low, then the edges of the tyre start to wear out. When its edges wear out, it generates more heat due to which its rubber starts to deteriorate.
4. Bad Roads: If you travel on some very bad roads, then this also reduces the life of the tyre. This damages the tread and sidewall of the tyre.
Â
4. Fast braking and sharp turns: If you take a sudden turn or apply fast brakes while driving the car, then this also causes wear of the tire.
5. Unbalanced tyres: If the alignment of the tyre is not correct, then the tire is greatly affected. Due to this, its life is reduced.
6. Excessive use of tires: If you do a lot of long journeys, then this also reduces the life of the tire. Take breaks from time to time for long journeys, so that the tyre does not get too hot.
Here we have shared some easy tips, which help in ending the life of the tire before it expires. Apart from this, many other factors reduce the life of the tire such as: rough driving, humid environment, excess weight or all-wheel drive or front / rear wheel drive). All these methods help in reducing the life of the tire. You should drive your car by avoiding these methods.
How to identify that your car needs tyre replacement?
Many times we face this problem, that we do not even know that our car needs tyre replacement. We should keep in mind some things like a frequent puncture of the tyre, less tread of the tyre or noise coming from the tyre while driving the car..

What We Will Do When the tyre manufacturing date not clear?
Many times this thing becomes a big problem for us. Because if you are thinking of using an old tyre then many times brokers reduce this date or due to some cut in the tyre, this date is not visible. In such a situation, by doing some identification, we can find out whether we should use the tyre or not.
- Look at the tread. If the tread of a tyre is less than 1.6 mm, then it should not be bought, no matter what the manufacturing date is.
- Retirement range: If the tyre has not been used at all, or has expired, then also it should not be used.
- Contact the tyre manufacturing company: By contacting the tyre manufacturing company, you can find out about the manufacturing date of our tyre.
- There is a map inside the tyre that indicates its manufacturing date. You can find out from the company or a tire expert.
Without looking at the manufacturing date of the tyre, you can identify the tire with the time mentioned. But you should do this with great caution. If the manufacturing date of the tire is not visible on any tire, then it would be better not to use it.
In this article, we have told you about the manufacturing date of the tire. After reading this article, it will be easy for you to read the manufacturing date of the tire everywhere.
The manufacturing date tells how old the tyre is now or how much it should be used. Every company has guidelines for its tires. Many companies allow their tires to be replaced in 5 years and many in 10 years.
