As a BMW driver for many years, I start with door plate/placard pressures for normal loading, reference the wheel/tire size. Then tweak the pressures for best driving/road feel and wear/balance for the tires. Typically find BMW are not far off for my driving use.
I've found RFTs usually require a slightly higher pressure to prevent odd wear patterns. Some of this is the slower warm up rate and tires fail to reach full working pressure on short trips, or in cooler ambient temperatures.
