Just an update on my experience w/ the 225/45/15 v720s. They feel good on track but I dont have any back to back data where the car was setup the same or on this same size, so I can't give a direct comparison... But heres how they look after 4 events, one of which was only 3 sessions, the others being 4-6 20 min sessions. I diagonally rotated them after each event (but forgot to alternate front to back rotations), camber is -2.6f/-2.3r, ran at 25psi hot.

Hard to see maybe, but the rf and lr tires are definitely doing something odd in the center rib. I started out running these at 35psi hot, but was only getting wear marks on a very small contact patch, and they felt odd under cornering like you were rolling over on them as if they had a rounded cross section in contact with the pavement... gradually aired down to 25psi and contact went all the way out to corners where you'd expect and handling felt normal.
These are 225/45 on a 15x9 wheel btw, on a 2340 lb car w/ driver, making approx 180whp.

Massive bump to this thread, but it looks like I lost that center section of my thread everyone else seems to be losing. The tires were at the end of their life anyway, but this was with 100% street driving. Nothing on the track and they still fell apart.
