Cold Tire Pressure
For those with the 20" AMG wheels, what cold PSI are you running in your tires? I was surprised to see the placard in the door jamb indicates 39PSI cold. Although I have a coupe I'd imagine the recommended PSI should be the same as the sedan.

TIA

Play around with it, used to run 34 cold which felt fine

After a balance, tire shop put all at 39 cold which felt even better, only then did I realize it felt slightly sluggish at 34 like driving thru sand

S600
I am runing 39 PSI and the car has plenty of grip.
Mine is a 600 and I am averaging 22 MPG at 39 PSI.

I know it seems high, but the tires work--now If I can only wear these out and put on non-run-craps.

With the short side walls and stiffness of run flats, for comfort sake would it be better to run 32-33psi?

My coupe's recommendation is 32 cold and it rides nicely.
