I have no experience driving with ASR in the snow but the cars came with a disconnect button to deactivate ASR and the icon is a tire with snowchains on. The explanation I got was that with snow tires you needed some slip to penetrate the snow. From running these cars on the dyno I know that if the ASR is engaged the car doesn't accelerate at all.
