18" Tire pressure questions

[Varekai]

When I got my stang in December the tire pressure was at 41 on the computer, 4 months later it's at 39. Just wondering what most people are using for their tire pressure, I saw someone in another thread mention that they run about 32psi. I'm on the stock 18" foundry rims with the pirelli all seasons. What PSI is going to give me the best traction and MPG?

open drives door. read sticker.

Every car has the manufacturer recommended tire pressure in this location.

35psi cold for 20's on summer only tires. jumps up to 37-38 after 15 minutes of driving (nitro filled tires)

someone said ford ships these cars with 41 or 42 PSI, and the dealer is supposed to reduce the pressure, but most don't.

bump... can someone who has the 18" foundry wheels/pirellis verify what the recommended tire pressure on the door sticker reads? (I upgraded to these wheels from the stock 17s and just want to verify the recommended pressure). Thank you!

I have the optional 18 inch foundry wheels and the door placard says 32 psi. New cars sitting at dealer lots have their tires filled to max to help prevent flat spotting.

its 32 or 34 as stated above.
