Most tires will show the oval "mold lines" surrounding the production codes found on the sidewall. Looking at the photo of your defective tire, i can see an "empty" oval after the C3J, indicating the position where the date code is normally found. The opposing side should be identical, but including a 4 digit code in the last oval. If your tire doesn't have that date code, it might be a faulty batch where the plant FORGOT to add the date.
The local Goodyear tire plant used to sell cosmetic blems like this to their employees at a highly discounted price.
