Porsche's recommendation is 33 Fr, 39 Rear for "partial load." If you have rear warning at 39, then most likely your car was set to "full load" (driver, passenger, luggage). This setting could be changed by using the steering column stalk, go to "TPA," the rest is self explanatory.

Before installing Bilstein PSS10 coilover, my tires were set at 34-35 front, 40-41 rear. The stock car's suspension was so soft that I had to compensate by over-filling the tires.

After installing the Bilstein PSS10, I am now back 33 front, 39 rear. Hope this helps.

Unfortunately, one was the tire pressure sticker.

I got a low pressure warning (39 PSI) for the rear left.

What pressure should I have in the front and back tires. They are pirelli P zeros (Factory tires).

All the tire says on the sidewall is Max PSI 50.

Thanks
