I race at 100% and every time one of my tires is absolutely worn in like 5 laps. At Miami i spent 5 laps on hards and my right front was at 14%. The rest of my tires were at 3%.
Ideas
I may have solved the issue I was having in Miami, although it's not specific to that track as I have tested this out on others since and they all have the same issue. In full practice (60 mins Long race lengths) a hard tyre is showing as having around only approx 15 laps of life. But in qualifying and race it's showing anywhere between 30-40 laps. Surely this is a bug.....
