Tire pressure
Can anyone tell me the best pressure to run the OEM 2013 C 300 4 matic sport 18" AMG 5 star wheels usually I go -10% but as this is my first MB I thought I would ask !

I have 33/38 recommended on my door. I've kept mine on 33/37 only because the car maxes out at 2.5 people.
Try it. Run it 10% under vs the correct pressure. You'll find the higher (recommended) pressure softer.

Much thanks
Any reason you're running it soft? I also have those wheels and there's not much sidewall on them. I find that keeping it at the the door jamb pressure gives it the softest ride. Deflating a 35-series tire maxes out the sidewall deflection on bumpy roads and manifests as a harsher ride.

I will definitely run it as you suggest. i did notice something was off when I had to gas it and make a very quick move left and right and back left to avoid a major collision on the freeway (California drivers in the rain ) I felt a bit more body roll than I would expect that's what prompted me to look at the tire pressure . Now in all fairness I do also drive a suburban on 24"s (street tires) and a 05 G35 coupe that is dialed in fairly well that car sticks to the road ! I have only had the MB a few weeks ! Thanks I appreciate it !
