Yet somehow the tire seems to work better with pressure between 38-44psi, the car just has more grip with the high pressure. It is odd to say this, but I recommend 38-42 cold pressure on the R888 (a tire which I hate). I think Toyo recommended the same thing.

Most people get the feeling that the side is actually a bit softer than some DOT race tires. I get that feeling when driving them. The lighter the car, the stiffer they will feel.

38-44psi is on the high side, but if your setup allows you turn faster lap times, then do it. The stopwatch doesn't lie. If I ran mine that high, I would be slipping all over the place.
