Believe I have this right....

Mfr. date stamp on SIL's new front tire: 0620.  I read that as 6th week of 2020, meaning a mid-February mfr. date.  Correct?

Sounds right to me:

"The last four digits of this code tell you when your tire was manufactured. The first two numbers indicate what week of the year it was made (out of 52 weeks per year), and the second two numbers represent the year. For example, 5200 would reveal that a tire was manufactured during the 52nd week of the year 2000."

That is correct  6th week of 2020
