I am putting a dot more with PSS and goes fine imo. 2.4 f/2.3 rear. Or 36 to 34 psi. Really depends on where and how you use the car and worth trying different pressures to find your prefered spot. You should do this experiment after the new tires break-in, makes more sense. And PSS do need a proper break-in, careful with heavy braking and like till a minimum 300 miles or so. Best is to make a longish and relaxed highway trip to take out the covering protective material.
