By the time GT got passed Michael, for the 1st time, my tyres had already started to go off and my pace drop. All I could do then was watch them disappear off in to the distance. The shenanigans at the start meant no one was close behind and the last half dozen laps were rather tedious.
Forgot to mention this. If you were using the default setup, the tyre pressures were way too high here. With default I was getting almost 39 psi, and 33 is optimal.
My starting pressure, especially the front left, was around 20 psi, and even then it went to 35 at some points. That might have caused your high wear, as my tires were still fine at the end.
Also, the 100% damage seems a bit high, I had very light yellow damage but lost around 10kph on the straight and around 0.7 of a second per lap. i don't think high damage will give safer racing, as I think everybody here is fair and won't do anything wreckless on purpose.
