I've seen this before from too much pressure. What maximum psi were you running at?

Must not have checked? Did you ever rotate? 4 days on the same track, with an abrasive surface would do that to any tire IMO.

I joke a little, but when we buy new tires for the GT3, it really should be a 5 tire purchase. 3 fronts, 2 rears. The wear and heat cycles will match almost perfectly

Yes MPSC2.34 lbs all around on this set. Trying more bar in the rear. Triple front purchase is very smart idea.

Then blame the track, not the tire.

IMO, 34lbs hot is too much. I just replaced my tires after. nearly 10k miles, 3 tracks, and 7 track days. They were most likely heat cycled out after 5, but I had nice, even wear.
