How to Check the Date of New Car Tires?
2 Answers
The method to check the date of new car tires is as follows: 1. Locate the DOT (followed by a row of "code") on the tire, where you will find an oval circle marked with four digits. 2. These four digits represent the manufacturing date code, with the last two digits indicating the year of production and the first two digits indicating the week of production within that year. Below is supplementary information about car tires: 1. Aging Period: Major international tire companies generally set the aging period of tires at three years. Scientific experiments have shown that, regardless of the brand, new tires stored for three years will undergo changes in physical properties due to factors such as wear and oxidation. Indicators like wear resistance and other strength metrics will significantly decline, while the potential risk coefficient will correspondingly increase. 2. Precautions: Whether purchasing a new car, a used car, or specifically buying tires, it is important to pay attention to the manufacturing date of the tires.
As a friend who just got a new car, I'd like to share a little secret from experience. The tire production date is engraved in the last four digits of the DOT code on the sidewall; for example, '2323' means the tire was produced in the 23rd week of 2023. Even if unused, tires age over time, and rubber can harden or crack after about 6 years, affecting braking and safety. Before buying a new car, it's best to ask the dealer to show the production date to avoid purchasing a car with old inventory. I've learned to note down the date during regular tire checks to ensure they're in good condition. During each maintenance check, also look at tire pressure and tread depth—overall maintenance saves money and brings peace of mind. Remember, don't just focus on the appearance; the date is a key safety indicator. Developing this habit will help your beloved car serve you longer.
