I have a 2011 X5 5.0 (just purchased 6 weeks ago - love it) and live in Colorado - we take frequent trips to the mountains in the winter so I plan to fit my factory 19" 335 rims with Nokian Hakkapelitta snow tires in the next few months. I have the Continental 4x4 Contact SSR run flats from the factory and IMO they are the weakest link in the car's handling (although I think the car's overall handling is phenomenal). And, this summer I plan to add some 20" wheels with the best handling summer tires I can (reasonably) afford.
I bought the X5 because, for an SUV, it has great handling and sporting performance in a vehicle that I will be driving a lot with my family. I have 5 kids and we spend a lot of time in an SUV. I LOVE driving, and I LOVE Bimmers, so in my opinion it doesn't make sens to pay the $$ that I did for an X5 and not have optimal tires. This is just my perspective and I know not everyone will want to pay the extra to have two complete set of rims and high end tires, optimized for each season.
