That happened to me at summit, I first noticed when I was at main in end of march, it it was kinda cold that day which didn't help much. Tires got ripped up pretty good. Then I was at the WERA races back in april, it was 80 outside and sunny, during practice the tire got ripped apart even more in kinda a saw blade pattern similar to your picture. While riding coming out the higher speed turns I was feeling the rear shock compress, then rebound a little too quick which made the bike a little squirrly but also had to put a lot of stress on the tire. I added 3 clicks of high speed compression and took out a click of rebound and threw on a new rear tire for the hell of it. Bike felt tremendously better when I did the HW solo race, and the new tire showed no signs of abnormal wear whatsoever.
