I gave a professional drifter my car with newly mounted PSS and he did a 10 minute crazy 8 session on the balcony drift track at Willow Springs. I've also logged about 100 laps in 3 sessions between one day at Streets of Willow and two days at Big Willow and the tread is fine. Before each track session I started at 30/31 psi and they'd head up but nothing over 40psi. Great all-around tire.
