How to identify the authenticity of the tire and the advantages and disadvantages when replacing the tires and become a question that many car owners are very concerned。The tire is the foot of the car，Once the quality is not firm, it is easy to cause various safety accidents。

So how to judge the production date of the tire? Generally speaking，Tires will print four -digit numbers on seabet appthe position of the tire on the side of the tire when they leave the factory，These four digits are the production date of the tire。The first two digits of these four digits indicate the week of tire production，The latter two indicates the year of tire production。Through these four digits，We can determine when the tire is produced。If the production date of the tire is relatively long，It is likely to be inventory，We should ask the merchant to change the relatively recent product。

Of course, the tire "fresh -keeping period" mentioned above is only valid for genuine tires，If you encounter refurbishment tires，Then the above rules will not be effective。The biggest difference between renovation tires and genuine tires is the abrasion resistance，The driving mileage of renovation may be only half or shorter of genuine new tires。

There are some protruding signs on the car tires，indicate the model and performance of the tire，These are the breakthrough points of identifying refurbishment tires，The signs of the tires that are generally refurbished are re -posted after renovation，These logos of the new tire are integrated with the tire，The method of identification is to scratch these signs with fingernails，These signs of general renovation tires are not very tight，What can be removed is undoubtedly a renovation tire。
