How to Check the Production Date of Car Tires?
2 Answers
The method to check the production date of car tires: 1. The 11-digit number and letters immediately following the DOT letters on the sidewall of the tire represent the identification number or serial number of the tire. The last four digits of the serial number indicate the production date of the tire; 2. The format of the tire production date code is as follows: the first two digits represent the production week, and the last two digits represent the production year. For example, 1204 means the tire was produced in the 12th week of 2004; 3. Without turning the tire over, there is a group of four-digit numbers in an oval shape on the sidewall of the tire, such as 5106. The first two digits indicate the month of production, and the last two digits indicate the year of production; 4. On the sidewall of the tire, there is a group of numbers. The last four digits of this mark provide information about the production date. It consists of four digits AABB, where the first two digits AA represent the week of the year, and the last two digits BB represent the year.
Last time I changed my tires, I learned this trick: first crouch down and wipe the dust off the sidewall with your hand. You'll see a string of letters and numbers, with a four-digit number like '3521' usually at the end, meaning the tire was produced in the 35th week of 2021. Don't underestimate this—over time, the rubber on tires ages and cracks, which is especially dangerous at high speeds. I recommend checking the date codes on all tires every six months, especially after buying a car to avoid being tricked by unscrupulous sellers. By the way, also check the tread depth—if it's too shallow, replace them immediately. Safety first! In short, just a few simple steps: locate the sidewall code, understand its meaning, and consider replacing tires older than five years.
