You have to drive the car for a short while before the TPS warning clears.

AMG 17GT

And that's a hot PSI BTW

CarHopper

Which is also located on the inside of your drivers door.

The low pressure warning shouldn't take very long to clear, few miles.

Once you have the tire pressure set you can restart the TPMS.
-Key in position 2
-arrow over to the Service Menu
-arrow up or down to the Tire Pressure
-Press OK
-Tire pressure will be set after driving a few minutes
or
-Arrow down to Use current pressures as new reference values
-Press OK - Tire press. monitor restarted.

I know it can be a pain in the butt but try to "RTFM"

hahaha the forum is my manual

Interesting, why so high? I do 39-40 all around.

BLKROKT

Same here. 40 front and rear.

CarHopper

I'm just relaying what is on the inside of the door.

I'm right around 40/42 I believe. Been a minute since I've checked the pressure and am about to replace the front tires anyway.

Mine is exactly the same, can definitely tell a difference in ride quality if any higher/lower.

Mazspeed

Too high.

The dealer set mine at 44/46 hot. (ContiSport 18" 235/255's)

ETA: When I first got mine, it had been sitting in the cold for a few weeks and I got a warning for low pressure. I believe the door panel says 40/42 cold

Mort

The gas door says 41 front and rear cold with a medium load on my 2012 and 18" wheels. Is it not advisable to go up a couple of pounds on 19s?

beaststunt

I went with 40 all around seems perfect ,light went out didn't realize the tire rim setup I ordered only had 27 front and rear

CarHopper

K.

Should it be 44/46 hot? Or cold?

Mort

Tire pressure should always be done cold. If it is not possible to do it cold you should set it and check it later when it is cold. Best thing is probably first thing in the morning.

I actually go 38 all around and check often... on PSS.


On the PZeros, I followed factory pressures and wore out the middles badly in 7k miles.

abcut973

I do 42 all around.

Phil_T

In UK inside fuel cap says 38f 43r

Case1906

I like 38/40 cold

Girard@ACGautomotive

Dang you guys run them high. ~32 psi front and rear on mine. My back can't handle much more lol.

kukimonsta

I'm confused as to why fuel cap states different numbers than the door.

What's the ideal air pressure for street with occasional spirited mountain driving?

Is lower pressure for comfort only and higher pressure for cornering? I know with drag races the lower pressure in the rear is ideal.

I also noticed fuel cap stating 93 even though in Cali there's only 91
