What cmyX5go said. I took her and some others advise a few months back and now own a dedicated set for winter as well as the Diamaris for all other seasons.

My wife's '06 X5 (sport package 4.4 with 19's) was absolutely useless this last winter, even with brand new Michelin's. I haven't tried my new 17's and the winter Dunlops as yet, but I'm expecting a much different experience come next winter. From all reports, cmyX5go's included, I'm excited about the possibilities.

'Course, that little "I Dream of Jeannie" hip action figure should be convincing enough all on it's own.......

Congrat's on your new X5......we love ours. I'm convinced that it would be prudent if you would consider the smaller wheel/dedicated winter tire recommendations being offered.

Good luck...................
