How to Know the Manufacturing Date of a Tire?

[DiCora]

Tire manufacturing dates are marked on the outer side of the tire. Without needing to turn the tire inside out, you can find an 11-digit alphanumeric code immediately following the letters "DOT" on the tire's sidewall, which represents the tire's identification number or serial number. The last four digits of this code provide information about the production date. The tire production date code format is as follows: the first two digits indicate the week of the year it was manufactured, and the last two digits represent the year. There are 52 weeks in a year, so following this pattern, you can determine the exact production date of the tire. For example, if the last four digits of the DOT code are "4117," it means the tire was produced in the 41st week of 2017.
