Where to Check the Tire Date?
2 Answers
Automobile tire dates are marked on the outer side of the tire. You don't need to flip the tire over; it's on the exterior, specifically on one side of the tire wall. There is a set of numbers, and the last four digits of this marking provide information about the production date. Below are specific details about tire dates: 1. It consists of four digits "AABB". The first two digits "AA" indicate the week of the year, and the last two digits "BB" indicate the year. 2. Generally, the 11-digit number immediately following the "DOT" letters on the tire sidewall represents the tire's identification number or serial number. The last four digits of the serial number indicate the tire's production date. 3. The tire production date code format: the first two digits represent the production week, and the last two digits represent the production year.
The tire date is actually found on the sidewall within a small oval mark, containing four digits. The last two digits represent the year, while the first two indicate the production week. For example, in my 20 years of car repair experience, I often see codes like 1523, meaning the tire was produced in the 15th week of 2023. This date is crucial because tires start aging after about six years, becoming prone to cracks or leaks, which is especially dangerous when driving at high speeds. I recommend checking them every six months, along with measuring tire pressure and inspecting tread depth. When replacing tires, don't cheap out and buy outdated stock tires—spend a bit more for safety and peace of mind.
