How to Identify the Manufacturing Date of Tires?
1 Answers
The manufacturing date of tires can be identified by the markings on the sidewall of the tire, usually in the format of DOTXXXXX3115. The last four digits of the DOT code represent the manufacturing date of the tire. The first two digits indicate the week of the year, and the last two digits indicate the year. Here is some additional information: 1. Manufacturing date within 3 years: It is ideal for the tire to have a manufacturing date within 3 years and not exceed this period. Since the main material of tires is rubber, tires that have been manufactured for 3 years may already have aged, and using aged tires poses safety risks. Generally, tires manufactured more than three years ago should not be sold. Of course, the newer the manufacturing date of the tire, the better, as it indicates better performance. Typically, tires with a manufacturing date within one year are considered new, while those older than one year are considered stock tires. 2. Tire lifespan: Although tires have a certain "shelf life," it is not like food with an expiration date. The "shelf life" of tires is highly dependent on actual usage conditions. If the driver does not have poor driving habits such as sudden braking, stopping, or sharp turns, the lifespan of car tires is generally 3-5 years. Therefore, regular maintenance of tires can help extend their lifespan.
