Best street tire pressure for Sport Cup 2's ???

Hi all.

First off, I installed Pilot Sport Cup 2 tires on my Turbo S and all I can say is WOW! The grip is sick.

I went back and forth between these and the Pilot Super Sports, and since these new Sport Cup 2's have a higher treadwear rating than the original Sport Cup's and many here have raved about them I went ahead and took the plunge.

I don't track the car, but I wanted the best performance for the 3k miles I put on it per year.

I recommend them as a higher grade alternative to the other options we have.

Anyways, just wondering for those who have experience with these tires or the original Sport Cups....

I always ran 35/41 on the OEM PS2's and I had good handling and good tire wear.

Should I run the same pressures for the street on the new Sport Cup 2's?

Are the tires' dynamics different such that they need either lower or higher pressures? (Again, only for the street.)

Thanks!

I often have 3 kids in car but winters I run 33 psi and 36 psi and summers 36 psi and 44 psi.

I'm running 245 and 325 but would be the same for your tyres.
