How to Identify the Manufacturing Date of Tires?
2 Answers
The manufacturing date of tires is marked on the outer side of the tire. You don't need to flip the tire over; there is a set of numbers on the sidewall of the tire. From the last four digits of this set of numbers, you can obtain the production date information. It consists of four digits, 'aabb', where the first two digits 'aa' indicate the week of the year, and the last two digits 'bb' indicate the year. Here is more information about car tires: 1. The 11-digit number and letters immediately following the 'DOT' letters on the tire sidewall represent the tire's identification number or serial number. 2. When replacing tires, always ensure that the replacement tires match the size specifications of the vehicle's original tires and that all four tires on the vehicle have consistent size specifications.
Identifying the manufacturing date of tires is actually quite simple. As an experienced driver with years of driving under my belt, I make it a habit to check during maintenance. Every time I see a combination of numbers and letters on the tire sidewall, that's the DOT code. The last four digits can tell you the date: the first two digits represent the week, and the last two digits represent the year. For example, '2519' means the tire was manufactured in the 25th week of 2019. If there are only three digits, it's an older tire, indicating it was made before the year 2000. Don't underestimate this; tires naturally age, and when the rubber deteriorates, it can easily crack or blow out. I've seen many accidents caused by this. Generally, it's recommended to replace tires every five to six years, not just based on tread wear. Make it a habit to take a quick look when washing or repairing your tires—it's safe and worry-free. When buying new tires, also pick ones with a fresher date to ensure a few more years of reliability.
