20-inch Michelin Pilot Sport Summer Tires--what pressure do you opt for?

[marc]

My 4s was delivered with 42psi front and rear. I'm finding mixed information on pressure--any recommendations?

Check the door sticker.
I run 39psi cold in all tires. Some people will say that this is for full load but the same sticker also has the max allowed weight which is enough for only 3 adults, so the full load for this car is what would be partial load in other cars.

I believe I'm running 36/33 but I'll have to check. 42 will lead to some instability at higher speeds and I wouldn't recommend it.

This was covered in another thread, that door sticker mixed up kg with lbs. It was fixed on ‘21s.

36 front
33 rear
Confirmed by my door sticker.

Yes I started that thread and I also contacted Porsche customers sercice. There is no confirmation by Porsche NA that it is a mix up, that is just your speculation.
Anyway I would still run the full load 39psi in all tires. It improves range, it will probably increase the tire life a bit and there is no noticeable comfort or stability compromise.

It's not speculation. I have a '21 and it's fixed. Unless you think it just happens that the '21 has a greater load capacity than '20 by the difference between kg and lbs.

I haven't seen the 2021 but I believe you. I wish Porsche NA would confirm instead of asking me to pay to get a copy of my car's spec sheet..
Can you post a photo of your sticker in the other thread?
