Depends on the load etc. As indicated inside the fuel door, there are several different recommended tire pressures for various scenarios. The most common normal load pressure with up to 2 passengers and no or light cargo for 2019+ is 33f and 32r. That's what I've been running mostly. In Europe I raised it at one point for max speed driving, but the ride became terrible and very bouncy. Ended up lowering it back down to normal load as I only spent brief moments above 155 mph.

Thanks for the info. I've had my C63s for only a few months and never looked at this chart assuming it was octane requirements being on the gas cap door. I used the tire pressure sticker on the driver's door well which only states 46/48 psi. I guess this is for maximum load and speed. Not clearly stated on this sticker that there are other reccomended pressures for other conditions.

Yeah, the driver's door sticker in the USA is virtually useless. I believe it does say to read the owner's manual for additional information and if you follow that advise you'll find out about the fuel door sticker. This is one of those silly DOT regulations. By law the door sticker must only show the highest recommended tire pressure, which is for max load and max speed. It dates back to the Firestone debacle and the resulting deaths from drivers using the wrong recommended pressures. The DOT decided that Americans can't comprehend different tire pressures for different situations so they mandated that the door sticker shows the highest and safest recommended tire pressure, regardless of the potentially horrible ride quality that results from it. Some manufacturers, for example Audi, prints the additional tire pressures directly in the owner's manual. I like the way MB is doing it by putting them inside the fuel door, so you always have them handy if you need to temporarily raise it when you load up the car.
