Hi folks - Looking for any experience with Trofeo R hot tire pressures for the 360/430 to use as a starting point. I'm running 235/285 at -2.5/-1.8 degrees neg camber. Looks Pirelli recommends 30psi, and I've found running RE-11s at 34-36 to be even. Looks like porsche guys and folks using the older Trofeo tires put a bit more pressure in the rear too. So, I would guess that 30/32 would be a good initial target?
Porsche recommends much higher pressures in the rears than Ferrari does. I'd stay with your initial feelings and not be swayed by the Germans.
Trofeo Rs seem to like less pressure than MPSC2s which are happy in the mid-high 30s hot. I would try targeting 34psi hot. Bleed them to 30 and see which one feels better. A probe type pyrometer will help a ton as well.
So, I went out at 25psi front and rear, and ended up around 32, so shaved off another couple psi. Tire temps seemed pretty darn balanced at 30 F and R. I was really surprised how much these tires roll on their sidewall. Could really see it in the front still shots of the car in corners. Really not pushing the car, so probably some refinement is due in the future.
