Dam things are a pain for inner wear unless spot on with pressure. What have most people found the best?

I did alot of searching for correct pressures when I got my 19s too - I'm on same tyres as you and running 41 psi on the rear and 37 psi on the front. Hope that helps !

2.7Bar on the front and 3.2Bar on the rear for me.

PSI measurements are:

40/46 (or thereabouts).

EDIT:

this is on 19" 225m wheels which are 225/35 and 255/30 (front/rear) and on the OEM Bridgestone RFT.

0.2 bar above whatever BMW recommend worked for me.

I had inner wear after 18k miles on the RFT's (although they were possibly a bit under inflated). Used 0.2 bar over and saw even wear across the tyres over the next 6k miles.
