Ilisapesi

I am almost ordered 9-4x AERO. There is a small problem. 235 55 R20 are too low profile for my taste, i am getting this car to drive hard on bad roads. So i think about getting 18 inch wheels. But i heard that drivesense won't work good with 18 inches wheels? Is that true? Also there are no good tires, especially for cold winter in standard sizes both 20 and 18. So i am planing to use 255 60 R18. But not sure about drive sense and car behavior.
