I'm about to buy 4 winter wheels+tires for my X5 E53; I've been told that the 19" 285/45R19 and 255/50R19 I currently use are too wide and for best ice/snow performance I should choose a 17" (235/65 R17)
Are 17" so much better on snow than the bigger 18" ?
Does anybody use such a small wheels on X5 ? How does it look ?
Even though it's just for 3-4 months / year I don't want the car to look ridiculus :-)

Thanks
Nico.
