How do you "see" "belt separation" (which I thought was an internal structural failure which usually has no external symptoms until the tyre desintegrates) from the outside of the tyre anyway?
I'd guess your tracking is off, so your wheel is excessively toed-in, which is wearing the tread on the outside. But I'm no expert.
There's quite a bit of cracking. I'd say its cosmetic, and I might treat the tyre with a protectant to slow it down some. But I'm no expert.
Anyway, I'd say you can't go wrong with counsels of perfection, so you'd better buy new tyres. Or maybe a yacht.
Below I'll put the link to a post I had last year about the exact same thing with my tire.
How I know it's belt separation, is because CapriRacer told me so on that post. He's a tire engineer.

Concur. Those 2 photos are of the bulges you get when you have a belt separation.
Technically, we don't have X-ray vision, so we can't be sure, but the overwhelming majority of the time, a bulge like that is from a belt separation.
If left on the car, eventually the top belt and the tread on top of the top belt, will peel off, exposing the bottom belt, and doing damage to the fender as it comes off. Usually the tire does NOT deflate, but sometimes it does.
