I have a 4.4i w/sport package. It has the 19" Michelins Diamaris that don't look like they'd be very good in the snow (skiing in the Cascades and BC). I bought 18" BMW wheels and the Michelin 4x4 XPC's. The other choice were the Pirelli Scorpion ST's, but the XPC's looked like they had a better tread pattern. They're the stock tire on the new Range Rovers at the Seattle dealer. I'm glad someone else came to a similar conclusion. I haven't mailed in my coupon for the emergency kit yet. Where's the Nokkia review posted?
