Plugged tire?

[Bretty]

I would change it because the insert is no longer flush with the outside of the tyre and because of the uneven wear around it.

I have no concerns about riding on a well repaired tyre, and would keep an eye on it, but in this case it's clearly created a point of weakness that isn't getting any better.

I'm not sure what an insurance company would say if you were to have an off as a result of this tyre failing?

If you're tight (like me) maybe discuss with your nearest tyre centre the option or re-repairing it?!
