Good Year Wide Tread GT - Dating

[DWCamaro69]

Trying to figure out if my Good Year Wide Tread GT spare tire for my 69 Z is an original or a replacement. Date is: UN05D33
YH rally is K 1-9 5 19 YH
Probably going to sell it here and need to know what I am selling.
Thanks!

I believe wheel is May 19, 1969 correct? I have no idea on tire and can't find any definitive info.

Probably original.
