Pressures do vary depending on setup. According to the M3/4 owner's manual (for speeds below 160km/h / 100mph):
Summer 255/275 on either 18 or 19: 31psi front / 31psi rear
Winter 255/255 on 18" wheels: 31psi front / 33psi rear
Winter 255/255 on 19" wheels: 34psi front / 37psi rear

Thanks for that, what's interesting is the sticker on my door say 32/32 which is where I kept the 255/275 summers. The 1 psi difference between the manual and sticker is a wash for me, meh it's close enough for me
Plus my tire pressure gauge has a +/- 1% accuracy.
I checked my 255 square winter setup and the pressure is in-deed 34/37 at the tires.
