It is a little hard to tell from the picture, but I believe what I see there is actually a failure of the tread to sidewall ply. As if the tire were run with a significant alignment issue and wore the edge severely, or were run nearly flat.

I'm going with ply failure (for one of the two above reasons) as it looks like the edges of the opening have torn polyester ply(s) visible.

If it is a recap, it's more than just tread seperation. It's an actual failure of the original tire carcass. Meaning not only is it bad, it is not suitable for another recap either. It's a "shredder" tire.

Obviously replace this one, check the dates on the other tires as well. Dates older than 5 years become suspect pretty fast. Look for the four digit code on the sidewall. The first two digits are the week of manufacture, the second two are the year of manufacture. If I recall correctly, this marking was mandatory after 2000 and some makers did it voluntarily prior to that date.
