Is the higher pressure to improve bite/turn-in? Reduce uneven wear? Or for optimal comfort?

Just interested to know whether it's a ride setup preference, or just a broader known issue with none-RFTs.

Thanks,
Just a recommendation from Michelin and Pirelli, and if you look at the pressures on previous BMWs with the same size wheels they are always a little higher.
You have like 32-34psi on the E90 with run flats, and on the E46 it was 36-40psi.
