I bought these wheels with like new French Continental rubber on them. I have tried deciphering the DOT number (Dot LLRB 3TN) but drawing blanks. Can someine pls help me figure out how old they are?

The date stamps are sometimes only on one side.

Past 2000 it will be 4 digits stamped INTO the tire.

I've never seen a date stamp with raised features.

Pre 2000 it sometimes was a three-character (could be alphas) stamp and was not consistent between manufactures. first two referred to week and last referred to year.

Anything usable will have the 4-digit code. (first two=week number/second two=year)

I have seen multiple recent examples of commercial tires (big equipment) tires that are not dated.
Tires that fit a 914 are not in this group.

If those tires are actually meant for sale and use in France it's possible they don't fall under a DOT requirement for dating.

I have ZERO knowledge of French Automotive regulations...
