Just ran 2 days on brand new 225/45/15s in my 2350 (with me in car) turbo miata on Autobahn South track and loved it. Kept tire pressures between 34-36, 2psi higher front to rear and wear was very very nice. I haven't checked them after my last couple sessions, but the 1.5day mark they were even and looked very healthy.
Temps first day were ~70. It hit almost 80 on the 2nd day. The car stuck like glue and they squealed nicely at the limit.
So far I'm very happy that I picked them for my new HPDE tire.
