I think the clue is that the first number can go past 12, I have 35-21 on one of my tyres.
How do you read a tyre date code?
The first two numbers of the 4-digit DOT date code (which, again, appears at the very end of the string of letters and numbers that start with DOT)
indicate the week that the tyre was manufactured. The last two numbers of the date code tell you the year of manufacture. In the example below, the date code is 0517, which means that the tyre was made in the 5th week of 2017. If the date code has only three digits, it means that your tyre was manufactured before the year 2000, when a different system was used.
