Typically you start 5-8 psi higher than BMW calls for an adjust according to the tires performance, your skills, the track, etc.

thanks for the response. so 5 psi hgher? i would think keep standard as the tires heat up, no? so if its 35 then start with 40? what happens if they get up over 40, reduce heat betweens runs?
