Proper tire pressure on PZero 22"?

[damienhou]

Hi folks,

I just got my car back from its first service today and noticed that the dealer put the cold pressure to 43.5psi. According to the door card cold pressure should be 49 though so I'm confused. These are PZero on 22".

49 is for max load on 22s with 190mph top speed. I would not be driving around at that pressure normally. Check the manual for recommended pressures and tweak as desired. Page 269.

FWIW I usually run 39 to 40.5 PSI on the 22s and 40.5 to 42 on the 21s for winter. Run winters a little higher to account for outside temperature drops.

Yikes I never follow the cold pressure on the door on any of my vehicles. Look at manual for proper normal load pressure. I ride 38 psi on my summer Michelins and winter Vredestein tires..

Interesting as my door sticker reads 41 psi.

That's recommended max load psi for 22s at 155mph top speed IE steelies with air suspension.

I run mine at 36psi cold.

Lol, I guess I have to RTFM!

In case the vehicle didn’t come with the manual.

Thanks! Time to RTFM for me.
