I am going to be taking my '17 Turbo S to the track. It has the standard issue Pirelli P Zero's. Does anyone have a recommendation on what hot tires pressures I should run?

I played with my pressures and didn't really get anywhere. My advice is to launch the car in Sport mode with PDCC off. Sport+ / PDCC doesn't make more power at full throttle but it does stiffen the rear suspension up, and that will lead to more tire spin. I got my best trap of 132mph with the A/C off, Sport mode, TC off and launch mode. I got my best E.T. with sport mode, A/C off, TC off and launch with just step n' stab.

Thanks for the input. I guess I should have been more specific. I will be doing road course driving, not drag racing.

I've done about 4 track days so far and start 30/32 cold and finish my 20 min sessions at 35/36 hot. This has worked well for me so far, but more experienced drivers will surely chime in, with their toughts.

Keep it below 34 hot.

Generally somewhere between 30-33, depending on your setup and driving style.

You want to be a lot softer for the road course. Start at 26 rear, 28 front assuming cool am and car is OEM, no mods. Goal hot rear is 30, front 33 or 34. You might want to read the Tracking the Turbo thread. Enjoy!

You can launch control in sport mode?

Depends on the tires, cars alignment, the wether, the track and your skill.

1st time at the track?...just run the lower comfort pressures. 1st time at track you won't be anywhere near the cars limit.

Rule of thumb is keep the hot pressure less than 35/36 psi. However no way for us to tell you were to start because we do not know the answers in my 1st sentence. However if your pressures go higher than 36 you are not going to hurt the tire at all.

Thanks for the intel. I regularly track my 991 GT3 and know what works for it, but didn't have any idea for my 991.2 Turbo S.
