How to Check the Manufacturing Year of Tire Specifications?
2 Answers
The method to check the manufacturing year of tire specifications is: 1. There is a set of production batch numbers consisting of numbers and letters on the outer edge of the tire. The last four digits of the production batch number indicate the manufacturing date of the tire; 2. The four digits are in the form of AABB, where AA represents the week of the corresponding year, and BB represents the manufacturing year. Tires usually have many numbers and letters, which represent different meanings. Most tires have a DOT mark, which stands for the certification by the U.S. Department of Transportation. It is usually followed by a series of numbers and letters, representing the tire's origin information and factory code.
Checking the production year of a tire is actually quite simple, mainly by examining the DOT code on the tire's sidewall. You'll find a combination of numbers and letters, such as a four-digit number at the end like 3423, which indicates the tire was manufactured in the 34th week of 2023. I always pay special attention to this when driving because aged tires are prone to blowouts, especially on vehicles that have been sitting for years, posing significant safety risks. Generally, tires should be replaced after 6 to 10 years of use, otherwise, they may cause loss of control on the road. When checking, you need to crouch down and look closely to avoid confusing the front part—the key is the last four digits. It's advisable to check this during every maintenance session to prevent unexpected incidents.
