Where to Find the Manufacturing Date of Car Tires?
2 Answers
Car tire dates are located on the outer side of the tire. More information about car tire dates is as follows: 1. The car tire date consists of four digits "AABB". The first two digits "AA" represent the week of the year, and the last two digits "BB" represent the year. 2. The 11-digit number and letters immediately following the "DOT" letters on the tire sidewall indicate the identification number or serial number of the tire. The last four digits of the serial number represent the manufacturing date of the tire. 3. The format of the tire manufacturing date code: the first two digits indicate the production week, and the last two digits indicate the production year. For example, if the last four digits of DOT are 0807, it means the tire was produced in the 8th week of 2007, i.e., late February 2007. 4. The manufacturing dates of all four car tires should be consistent and not significantly different from the car's manufacturing time.
I learned when changing tires that the date is found on the sidewall! Usually near the rim, look closely for a small oval or square printed on the sidewall with four digits like '1623', which indicates the tire was produced in the 16th week of 2023. Key points: the last two digits represent the year, and the first two digits represent the week number—don’t mistake it for other codes. Why is this important? Tires stored or used for over six years can age and become brittle, affecting safety. I always clean the sidewall while washing the car to check the date. When buying used tires or a new car, I also pay attention to the production date to avoid tires that have been in stock for too long. Other tips: While you're at it, check the tread wear depth and any cracks. Proper maintenance can extend tire life by several years. I’ve made it a habit to do this before every long trip—it gives me peace of mind.
