I got the Crossfires (80 psi) and when talking to the dealer he told me if I wanted to reinstall the hubcap (plastic cover over the lugnuts) I would have to cut a notch on it so the Crossfire would fit. I have not installed them yet (rain and cold and doctors appointments). I will let you know when we do.
I'm in the same situation. Maybe after winter. Looking at it - it should not be that hard.
