Actually no way to know for sure. At the youngest it would be 10th week of 1992 and at the oldest anything back to when they first started dating tire manufacturing. Nearest I can find that would be May 1971. So our tire could be the 10th week 1972. It started with a three digit code and changed to four digits in 2000.
National Traffic and Motor Vehicle Safety Act established a requirement in 49 CFR part 574 dated May 28th 1971 at the youngest my tire is 32 years 7 months 20 days old.
