Haley Moran · Answer 1

Tech B is saying correct.

Explanation:

Yes, tires are provided with date codes but those date codes are correlated with manufacturing or production dates and not with the date of discarding. But it is difficult to understand or decode the date code. The tires with 3 digit code represent very old tires while the tires with 4 digit code are made after 1999.

In the four-digit date code, the first two digits indicate the week during which that tire was produced and the last two digits indicate the year of production. So the statement said by Tech A is wrong and the statement said by Tech B is correct.
