There was a piece of news that was quite hotly discussed a while ago, that is, a car owner spent millions to buy a new car. After taking the new car home, he discovered that an old tire had been mixed in by the businessman, which made him very angry. In fact, as far as this matter is concerned, as long as the tire looks clean and the brand name is the same, most people probably won’t notice any difference.
But if you are fooled by an unscrupulous operator, it will be harmful to your driving safety. The website “CheckTire” introduced this time can quickly let you check the manufacturing date of the tire, allowing you to easily grasp the information of the tire. In addition to using this website to check the tire manufacturing date, this article will also teach you how to quickly identify the tire manufacturing date to avoid buying old tires that have been stored for a long time:
Things to know when buying new tires
Before making inquiries, let’s take you through some knowledge about tires. According to information provided by the Bureau of Standards and Inspection of the Ministry of Economic Affairs of my country, tires with a manufacturing date of 6 years must not be imported or installed on cars. It is also recommended that the service life of tires should not exceed 10 years from the manufacturing date. As for how long a tire can run, it still depends on the tread pattern and driving habits, because rubber will gradually age. Even if you don’t drive often, the tire may crack, harden, deform, etc. due to being stored for too long, thus affecting the performance of the tire. It is recommended that you return to the factory for maintenance regularly so that you can keep track of the car’s condition at any time:
CheckTire Check tire life
CheckTire It is a very simple tire life query tool. Just find the DOT code on the tire to quickly query:
How do I find queryable codes? There is also a simple demonstration tutorial on the CheckTire page. To put it simply, just find the word DOT on the tire and use the last number to query. If your tire number is three digits, it means the tire was produced before 2000, so change it quickly!
For my car, the number at the end is 4221. After searching for the code using CheckTire, we can know that it is a tire produced on 2021/10/18:
Even if you replace tires of the same brand at the same time, you will encounter that the four tires are not necessarily produced on the same date. For example, my right front wheel is a tire produced on 2021/10/11. However, this situation is within a reasonable range. As long as the tires are of the same brand, model and size, the error is acceptable within one year:
In addition to cars, motorcycle tires can also be queried. In the same way, first find the DOT code, and then find the last number. For example, my rear wheel was replaced in 2023/10. I found that it was produced on 2021/03/22, and it is also within a reasonable range of use:
My front wheel was replaced around 2022, and the condition is still quite new. I mean, the manufacturing date of this wheel is later than that of the rear wheel, which shows that the store has no business (? XDDD
Quickly identify tire manufacturing date by yourself
If you are too lazy to use tools to check, you can also quickly identify the tire manufacturing date by yourself, and you will not be fooled when you learn! In the same way as above, you can quickly identify it by finding the last date code after DOT. Take this set of tires 4221 as an example. The 21 behind the tail means it was manufactured in 2021, and the 42 in the front means it was manufactured in the 42nd week. After conversion, this tire is approximately manufactured in 2021/10. Although the detailed date is not as accurate as using a tool, you can quickly identify the manufacturing date of the tire this way.
After reading the article, you might as well use this method to check the tire manufacturing date of your car! After that, when changing tires, I will be able to understand more clearly whether I am replacing them with tires that were manufactured in the same year, and I will no longer act like a sheep to be slaughtered!
