    I tried searching, unsuccessfully. If it's been answered ad nauseum, forgive me.

    For my '99 360 -
    currently: 18" Starfish (7.5 & 10, I believe) w/ 225/40-18 & 285/35-18, front & rear.

    I've purchased 19" Challenge wheels in 7.5 & 10.

    Assuming I stay with 225 & 285, do I go with 225/35, or 225/40 fronts? I believe 285/35 is correct for the rear.
    I've gotten conflicting information, so a definitive, correct answer from the forum would be appreciated.

    Cheers.

    The Challenge used 225/35-19 and 285/35-19.
