How to Check the Production Date on Car Tires?

[StevenLynn]

To check the production date on car tires: The tire sidewall will always have a production date identifier, usually in the form of a four-digit number. Following a series of alphanumeric characters starting with DOT, the last four digits represent the production date. The first two digits indicate the production week, and the last two digits indicate the production year. For example, 2320 represents the 23rd week of 2020. In addition to the production date identifier, the tire sidewall will also have markings like 225/45R1791W, which correspond to the tire width, aspect ratio, tire type, rim diameter, load index, and speed rating.
