How to Check the Production Date of a Tire?
2 Answers
Every tire displays its production date on the sidewall. If consumers want to determine the production date of a tire, they can look for a series of letters and numbers on the tire sidewall, commonly known as the Tire Identification Number (TIN). Here’s how to check the tire production date: 1. Tire Production Date: The 11-digit number and letters immediately following the "DOT" marking on the tire sidewall represent the tire’s identification number or serial number. The last four digits of the serial number indicate the production date. 2. Tire Production Date Code Format: 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. Tire Sidewall: On the outer side of the tire, there is a set of numbers on the sidewall. The last four digits of this marking provide information about the production date. These four digits are in the format "AABB," where the first two digits "AA" indicate the week of the year, and the last two digits "BB" indicate the year.
Finding the production date of a tire is actually quite simple, and I often remind my friends to pay attention to this. There is usually a series of numbers and letters on the sidewall of the tire, with the last four digits representing the production date code. For example, take "1523"—the last two digits "23" indicate the year 2023, and the first two digits "15" represent the 15th week, meaning the tire was manufactured around April 2023. Tires older than 6 years may age and crack, affecting driving safety, especially increasing the risk of blowouts at high speeds, so regular checks are essential. On a sunny day, crouch down and take a look; if the lighting is poor, use a flashlight. It’s advisable to glance at them every six months or with the change of seasons—developing this good habit can prevent major issues. Tires are the foundation of the entire vehicle, and negligence is not an option.
