Tire Reading and general tire help
TLDR: Can someone tell me what kind of tire wear this is? It basically has chunks missing. The track surface is VERY abrasive.
I was at the track this weekend on my Micheline Power RS. I'll be talking about my back tire only as I feel like that's the one I didn't understand well. I'll explain myself:
During the morning portion it was all fine. I was running the tire at 31 psi hot. I wasn't pushing it too hard or anything and the tire seem to respond fine.
During the afternoon, as the track opened up and we had more room I started pushing harder. The Kawasaki Traction Control (KTC) started kicking in mostly when I pin the throttle almost upright.
Towards the end of the day, things started to get a little out of my comfort zone. First, KTC started kicking in mid corners. Then, I almost high-side on a corner. I went back to the garage and decided to drop the pressure to 26psi hot.
I did one more session on 26psi and felt somewhat better but KTC was still kicking in mid-corner and I could feel the back tire slipping a tiny bit sometimes. I'm not expert or anything of course. I just got to Intermediate track day group. I know tire slipping is somewhat normal to a degree (if you control it and are pushing them) but it didn't feel right, specially for the pace I had.
Maybe I'm reaching the limit on the tire, maybe my throttle is sloppy, maybe the tire pressure is too low or high, or maybe Im completely clueless of what's going on. That's why I come here trying to get some help from knowledgeable individuals.
Attached is a picture of the tire in the hope somebody can tell me what type of wear it is. Please keep in mind the surface of the track is very* abrasive.
