I was initially shocked at the recommended pressures, especially the rears, but the car feels fine at these levels and I have a feeling the the lower profile of the 18" tyre, perhaps coupled with the sports suspension means higher pressures are required.

    I personally am not going to drop below 34,40, as I think you should follow the guidelines per the manual, I'm sure the car has been designed to work best with these pressures in mind. Saying that, 33,37 doesn't sound too bad, especially if you don't have sports suspension or drive mainly without passengers.
    I am with you on this one. My pressures are higher on the same size tyre. But mine is a saloon, and a 330d which would be heavier. If you ran a 323i coupe with my tyre pressure you would probably wear the middle of your tyres out.

    Bmw have made the calculations and they are far more specific.

    If it aint broke don' fix it

    i put 29psi in fronts and 40 in rears as per door plaque, and i am supprised to say the car feels spot on!, i don't know why i put 34 in fronts?, plaque clearly says 2.0 for 225 40 18 fronts!.

    It has always amazed me at how hard you need to have the tyres on a BM.

    I follow the plaque, but the set up for 2 people as I rarely have more than one person in the car. Can't remember exactly what the numbers are, but it is around 2.2 front, 2.6 rear.
