While prepping my Silvio for racing this weekend I prepared to install my new lightweight tires.
Below is my “old” rear wheel that won’t be going back on after the race. [sigh]
This picture doesn’t show the detail of the bulging tube but you can just make out the blue, flat-guard, lining that underlays the tread portion of the tire.
This one’s not fit for riding on anymore.
If it wasn’t a Schwalbe I am convinced I would have been walking home from wherever that occurred.
Oh yeah, and the front one? Also not going back on the bike after tonight…but for a different reason. [double sigh]
Guess that’s what happens when you ride little road bike tires a lot.

Wow!!
How many miles do you suppose were on that tire?

Is the tire in that top photo turned inside out? I’ve never seen a brown tire before, and your text doesn’t explain what we’re supposed to see. Is that a split on the inside of the tire?
The blue cushion layer is familiar to me. When I wore my tire down to that layer it didn’t take long before I had a flat.
I’ll look forward to a report on how your new tires perform.

Both tires have > 2500 miles on them.
The non-drive tire looks good except for the gash. Probably had another 2500 miles of life (or more) left on that one.
The tire appears brown because of the strange lighting. The tire is mounted and inflated in the picture; on the right is the braking surface of the rim, on the left in the bg is a blue plastic cup.
The slash crosses from nearly the apex of the tire 1/2 way down the sidewall all the way to the tube.

Since your drive-wheel tire (front) is worn to the blue flat guard, it is obvious that the driver has been “burning out” — to show off to the less-powerful “hot-rodders”?
