Whatever is on the doorframe of the car is what the tires are supposed to be set to unless that value is higher than the maximum pressure allowed by the tire manufacturer

The reason the pressures are listed on the door frame is that the car has been tested to react safely and predictably with those pressures. The tire manufacturers always tell you to inflate the tires to manufacturer's specifications on the door frame. There isn't much discussion beyond that except if you are looking to run them lower to improve comfort on 21" wheels when the car is delivered with 19's as stock. If that is what you are after, 21" wheels with lower tire pressure isn't really the answer.
