Strange tire weard

[ghoonk]

Guys, I noticed this on my semislicks after the last track day. Tyre pressures were 32 psi cold, and the tyres are 235/45/17 running on 17x8.5 Enkei RPF-1 rims.

Does anyone have any idea what is causing the marks in the red circles? Is this normal or is there something wrong with my driving

The car has no ABS, and I was able to get the rear to step out controllably on tight corners, and there was occasional scrubbing in corners where I went in too fast (this being my first time on semislicks, I didn't realize that my average speed has gone up significantly). Did not check tire pressures

Any advice would be great

possibly a little too high on hot pressures. did you measure them when you came off the track?

center tire wear is usually a sign of pressures being too high.

That's what I suspected, but before I jumped to any conclusions, I wanted to see if any of you guys had the same experience in the past and what was done to address it. I'll need to get a probe pryometer to measure tire temps from here on...
