Post cold tear?
The picture doesn't really do it justice, but I have a line of deep wear just to the left of the visible ring. Looks like chunks missing, that later got covered in migrating rubber. Chewed up an SC1 to less than 50% left in 5 sessions. I ran 34f 24r psi as the board showed that day, off the warmer. The next session I took maybe a pound out out of the rear (hot off the track) to maintain the 34/24.

I don't know if my woodcraft warmers ever got fully to temp either. I thought they were supposed to glow green after the first cycle? They were hot each time, with the red light on. (On the hot setting, not warm)

Any thoughts?

The warmers do go green once fully up to temp, but mine do stay red more than green.

I'm NOT a tire guy, but... I can tell at least *part* of the cause - because it's the same thing I do and continue to work on.. You turn in, get to full lean at "maintenance throttle", pick the bike back up a bit, and holyshitthatguyispullingawaymustapplyPOWAAAHHHHHH!! Mike (MDM) points this out on my tires damn near every time. His advice that I'll pass on is to work on cracking the throttle open earlier. "Ask" the throttle. 1-5% - Earlier. Even at full lean. This will extend the amount of time between 0% and 100%, which helps the tire. It also makes you faster, without making it dangerous. Somewhere I made a little graph that explains this, but hopefully you get the idea.

At NYST this weekend, guy on a 600 gsxr was running 24 hot off the warmer and this exact wear happened.

He dropped 2 psi to 22 and it sorted itself out no problem.
