The Stovebolt Site Forums The Shop Area Driveline Help with DOT date code on tires

I recently acquired a car with some nice wide whitewalls. I'm trying to figure out how old they are but the DOT code has me stymied because it doesn't follow the convention that I'm used to seeing. Here it is in its entirety:

DOT UPVV CA7054 A6L

The tire is The Untouchable by Cooper
Size G78-15

Thanks!
