Back with my "coasting" question. So it seems that the car doesn't coast because:
it has 20" 245/40 R20 summer (Continental) which needed to be 2.7bar
it sees 19" 245/45 R19 winter (Continental TS860) which needed to be 2.4bar.
I tried to set them to "auto". I've set them manually 245/40R20 but the car insists it has winter 245/45 R19
I tried to lower the actual tires to 2.4 front and 2.2 rear (as indicated) but it's clear to the naked eye that something is wrong. BMW states 32psi / 2.2bar for all 4 on X1.... mine is diesel, it has 1.7 tons and it cannot run on 2.2.
Any ideas ?
