New Guy, just bought an X5 - Winter Help :)

[machine]

Hi all,

I just bought a 2011 x5 35d Should be taking delivery of it very soon. I ordered the sport package with the optional 20's (style 214 Y Spoke) which will be horrible in the snow.

I was wondering what a good winter setup would be. I have already really stretched by budget on this truck so I dont want to spend more then I have to.

I was looking at putting Michelin Alpins on the wheels and going back to summer tires in the summer but the rear wheels would have to be stretched. I am not a fan of this for both curbing and other pitfalls of stretching a tire.

Other option is to get Pirelli tires that will fit but cost a fortune.

What should I do?
