So this is my supercorsa after two sessions of use.
The compound is SC1, the hot pressure was 28 and I did use tyre warmers, although it wasn't for that long, I think I only put it on for 15 minutes for the first session because changing wheels was a pain, and the second session I probably only had it on for 20-30 minutes. Originally I thought it was hot tear but looking at it again I'm not so sure, plus as Cerb said, it wasn't hot enough to be able to overheat a tyre at my pace. Is it cold tear? Plus there's also cupping on the leading edge of the tread, which I've read is due to rebound, can't remember if it was because rebound was too fast/slow.
There's probably a whole bunch of things that can contribute to this sort of wearing, but I'm not sure what they are so looking for experienced minds to shed some light.
