decode date for non-dot tire

[MosportGreen66]

Goodyear Power Cushion, non-dot tire

I think the date is: M - U (or D) - 0 (or O) - S - 4 - 3 - B (or 8)

Many thanks... Hope this is not too jumbled.

So you're saying it's something like: MDOS43B

Until the TIN (Tire Identification Number) format was standardized by the DOT in May, 1971, the tire manufacturers were free to use any proprietary format they wanted; pretty difficult to decode pre-DOT tire numbers without some really old paperwork.

Any info out there on how to decode a pre-'71 Firestone code?

What I think it stands for from my experiences:
MD-stands for The Goodyear Tire & Rubber plant located in Gadsden,Alabama.
OS-I believe stands for the mold number.
43-I believe stands for the 43rd week of the year.
8-I believe stands for 1968,in your example.

I am somewhat familiar w/pre 71 Firestones.What do you got?

On a 6.50x14 Firestone Deluxe Champion there is a code which appears to be: 019045JU.

Thanks for any help, Paul

I am not familiar with this format.
I will continue to research it.
