Through scientific experiments, it is known that no matter what brand of new tires are left for three years, their physical properties will change and their wear resistance and strength will decrease obviously due to factors such as oxidation. The major tire companies in the world set the tire aging period as three years, and tires that have not been sold for three years will be degraded or scrapped. Therefore, when buying a car or replacing tires, car owners should also pay attention to the production date of tires to avoid buying tires that have been in stock for too long and being deceived by profiteers, because storing them for too long will affect performance and even lead to dangerous accidents such as puncture.

1, check the tire production date.

Figure: The dot sign is generally stamped on one side of the tire, and the information of production date can be known from the last four digits of the sign, which consists of four digits "AABB". The first two "AA" indicate the week of the year, and the last two "BB" indicate the year. The number 1606 indicates that the tire was produced in the week 16 of 2006, that is, in April 2006.

2, check the tire anti-counterfeiting logo

In order not to be deceived by merchants, you should check the production date and anti-counterfeiting label when choosing tires. Genuine new tires will have anti-counterfeiting marks, which are usually attached to the tire trademark. At present, there are many anti-counterfeiting methods, besides the number of scraped coatings, there are watermarks and bar codes on trademarks, which can be used as methods to identify authenticity. It is suggested that you must be optimistic about the anti-counterfeiting logo when choosing tires to avoid buying counterfeit tires. Fake tires don't have anti-counterfeiting labels, or the anti-counterfeiting codes in the labels can't be found by SMS or Internet, so it's easy to identify.
