@RYUK is the clown who lives near me (said endearingly) and
raves about his Contis.
I didn't like the P Zeros until they were worn out. Lol. (I'm on set 2 of Pirellis AR spec .. and they're worn out)
The best tires I ever had after break-in were Kuhmo Ecstas and Proxes 888 (experience on other cars). I need lesser tires than those, because the things I could do with them was just wrong. At 53, I need to deliberately find a way to have fun at slower speeds. Like it or not, reflexes go.
I can say this about the Pirellis: After over a million miles of experience, I could feel how pathetic the sidewall works to destroy whatever compound and grippiness might exist on the actual tread and contact patch. You know by braking straight: Nobody is disappointed (ya know, for a good sporty tire on a stock car). Get the shoulder to come to the fight with proper balance of compliance and resistance and consistency when cornering? OMG.... the Pirellis can fu-k right off. Four killjoys along for the ride.
The thing about squirmy new tires and high UTQG numbers on extreme summer or autocross tires: If these factors converge, then it could be 1,000 miles before they are 'right.'
