    I know it doesn't really have much use in real terms, but interesting to see nonetheless what tires/pressures people use.

    Yours seem to show the max values based on the chart William posted

    It's a good idea imo, afterwards we can compare tire wear. I will post my size tomorrow, I typically run 32 front and 36 rear on stock size conti dws extreme contacts.

    Thanks! I felt it might be useful to have the info consolidated to a single thread.

    Correct, those are the values BMW gives for a fully loaded car i.e. five passengers with cargo.

    Table is updated with everyone who posted here.
