Running 195/50R15 R888's GG Compound. Running at 28PSI at the moment but I seemed to get a lot of wear down the inside of the outside half of the tyre if you get me. And I mean A LOT! Camber is at 1-1.5 deg.
I'll try draw something with lines, can you work it out lol!?

Thats from a driving position, 3 lines = 1 tyre, middle line is tyre centre, wear is where the * is!
Staying out between 20-30 minutes. I'll give them a go at that low next time. Cheers Any idea on the tyre wear or is it due to having pressure to high?
It'd normal to be wearing there if you're not running much camber as thats the loaded side on 90% of circuits and the cars leaning on the outside edge of the tyre a lot more without having a decent bit of neg camber dialled in.
Did you take your pressures after each session? You could even run the passenger side (If the circuit is clockwise) at 26, drivers still at 28 if you're not cooking them.
You dont want to be any higher than 35 mate. Do another session at 28, come in and see what they are then drop them to about 30 on the fronts, possibly go 2 psi lower on the loaded side and 32 across the rear. Let them cool and go back out and check them again after the same length session!
Ive just got back from Bedford and the R888's had absolutley spot on even wear. In fact they look no different to when we put them on. Were running then at around 2bar HOT in the front and 1.8bar Rear. Front will always go up more than the rear, had to let the fronts down twice from the original cold pressure.
Gonna check them in the morning to see what they have cooled down to
