I know it's not winter, but it will be upon us quickly enough.

I'll need to outfit my X3 with four snow tires, so I'm looking for recommendations.

The TireRack suggests Dunlop M3's, which I loved on my 330i, but aren't they car tires? Don't I need light-truck tires?

Also, do most of you get additional rims, or do you have the tires mounted on the stock rims?

Thanks
Andre
