what is your 918 tire pressure?

mine is set to 46, but doesn't seem right. did the dealer screw up? manual says 40/40 (and 30/33 for performance driving)

Tire pressure needs to be checked when tires are cold. Excessive driving increases the tire pressure.

45 all around when warmed up.

Dealer set

anonymous918

that seems high, no?

Whoopsy

Use 30/33 in you don't plan on going over 165mph. 40 all-around if you do.

918man

Wait. So my 45 warm is so out of bounds.

There seems to be conflicting info. The sticker in the door jamb doesn't agree with the owners manual. I split the difference!

anonymous918

what does the sticker on the door jamb say?

Email David D @ PCNA, he's logged plenty of hours.

If the inflation sticker is similar to my C2S, it'll give the pressure for max load at max speed. Also read the yellow sticker next to the inflation sticker as it says to read the manual and use lower pressures for comfort if not fully loaded and speed limited.

I can't exactly recall and I'm not with the car. Maybe another owner can post a pic.

Well, it depends on the use you give it.

The online manual says different...

Does that extra 1 psi between 40psi and 41psi gonna make a difference to most? It's only for high speed runs above 270km/h

Most owners should just stick to 30/33 and be done with it.

Oh, and on some videos the tire pressure warning was flashing when they do top speed runs, it's because even those press cars have their tire pressure set to 30/33. Even at that lower pressure the tires can still withstand the high speed for a while.
