Changing tire sizes and DSTC

    I have a '01 S80 T6 with 17" wheels (225/50R17) and DSTC. I'd like to get
    snow tires this year, and my Volvo dealer is recommending 225/55R16.
    Although the dealer told me that going to a new wheel size would be fine
    with DSTC, they've told me the opposite in the past. When pressed, the
    mechanic didn't seem too sure one way or the other. My owner's manual (pg.
    85) specifically states "Volvo recommends 215/55R16 winters tires on all
    four wheels". No mention of potential conflicts with DSTC.

    Is DSTC so finely calibrated that going to a different tire size (either
    225/55R16 or 215/55R16) would cause DSTC to act abnormally when active?

    Thanks in advance.

    I don't think that the size difference will make any difference to the
    DSTC system, but I'd certainly trust the engineers that approved the
    statement in the owner's manual over the dealer trying to sell what he
    has.
