The owner's manual has recommended pressures:

For the coupe 17" winters up to 20" summers are all 32/33psi.

For the convertible it's 32/38psi for 17" to 19" then 32/39psi for the 20" wheels.
Straight lines are for fast cars...turns are for fast drivers
'04 M3 - track
'06 650i Cab - daily driver
'02 Highlander - kid hauler
'01 330Ci - winter beater
