I got 15K out of my rear Dunlop but it was down to the wear bars. I replaced it with the C-II. I'll replace the front soon with a C-III.

It is indeed cupped, but I've seen worse LOL. Working on ordering a new set of tires now.

To the OP;
You have made several posts (bitched, but I don't blame you) about your problem:

Did you report this to NHTSA? (The National Highway Traffic Safety Administration)

Dunlop has had problems with tire compounds in the past, some recent, which have caused recalls.
(Actually, more than one, Google it.)

I just checked my original rear tire (D407) that I took off my bike at about 20K miles (it is still mounted on original wheel) …
There is no separation of compounds as in your pic., no dry rot, and is at about 7/64 tread depth.
Apparently Dunlop (or their parent non-US company Sumitomo Rubber Industries, Ltd.) has changed something to allow the tire to separate that way, and they have been called out on it for other tires.

Maybe it is time to call them out for these tires?

(maybe I should check my current tires???)

No sir, I have not reported this issue. Nor have I bitched about it. To the contrary, I started this thread asking about the separation I have, and no one else seems to have this problem. However, just yesterday I learned that a local friend has the same problem with his rear tire at 8k miles. Same bike, 2019 SGS, same tire, D407 in size 180/55-18. Maybe it's the desert southwest heat, who knows?

Dunlop's warranty does me no good as it's a pro-rated replacement warranty if I understood it correctly, and I don't care to have another one.

I've chosen to move on, and have purchased the new CIII to give them a try. How they'll hold up is anyones guess.

Here's a picture of the 8k mile tire I mentioned above.

I've just done a little research on the net and Dunlop tires are owned by Goodyear from what I can gather. So that's it for me with Dunlops as I've bought well into the thousands of tires for everything from 18 wheelers, farm equipment and passenger vehicles and believe Goodyear tires are nothing but garbage.
