Wow, I have almost 10,000 miles on my front Angel and 8,000 miles on my rear Angel. Of course I got 8,200 miles out of my front original tire on an '09 and almost 10,000 miles out of the rear original. I had a lot of long highway trips but thankfully here in Pennsylvania you can wear the sides as well.
What pressure does the OP run?
I seem to recall something on the old forum that said it was difficult to tell you were close to the cords on this tire and that one day, despite the tire looking good, the cords appear out of nowhere.
