something to keep in mind as well - most aftermarket wheels do not have the appropriate load rating for the rear axle of the X5. It's a personal choice to use whatever you want, but it was important to me when I was shopping for winter wheels last year.

I couldn't locate any oem X5 wheels locally and was on a tight timeline so I purchased aftermarket wheels. My first order through 1010tires.com was actually cancelled by them as the wheels I had picked didn't meet the load rating of the X, from there on in I was very carefull picking which ones to buy. It might not matter to you if you are not going to be towing a trailer or loading up the X5 with a ton of stuff, but I was, along with my family to drive across the country.

I ended up purchasing a set through Tire Rack, 18x8.5 square with the Goodyears I had mentioned earlier in this thread. After living through the worst winter in Winnipeg in the last 100+ years, I can say those tires are amazing!

I would also recommend either 17s or 18s to get a taller sidewall because you never know when you may bump into an unseen curb or who-knows-what in the snow.

Good luck!
