I am trying to determine the age of a set of old tires. They are General Grabber tires 31/10.50R15 it says DOT ADYK 924242 and another says ADYK 924232 What do these numbers mean ---

Look for another group of numbers, 3 or 4 digits. The date code is usually only on one side of the tire, you may have to go under the vehicle and check the other side of the tires. ---

This tire was made the 16 week of 2012 The last 2 numbers are the year, the first 1 or 2 numbers are the week ![Capture](https://global.discourse-cdn.com/cartalk/original/2X/f/f5f562e5a80411dc82ed7b84f1d365da3664c1a5.jpeg)
