How to spot a heat cycled out tire

Ok
I'm curious besides from driving on the track and feeling it out or timing, is there any way to know if an R compound has too many heat cyles from looking at it?

You can feel how hard the rubber is with your finger nail. Compare to other tires of known age/softness.

any funny colors on the edges of the contact patch?

Nope, looks the same color. I'll photograph them later.

Here's the photos. The tires don't feel particularly soft to touch. Guess, I'll have a point of comparison tomorrow with the other ones.

Harder to tell from a visual. The finger nail pinch will give you a clue. Remember you are buying about $1000.00 worth of tires for $200.00 so unless the previous owner has switched to a different brand I'd be a bit wary.
