Forecast says we might have icy mix tomorrow morning. It'll be the first in twenty years of my living in this part of country. I need to drive to work in early morning (around 7am) and would like to get advice from experienced drivers on what AWD mode to use if we have icy road condition and how to drive safely? Tallahassee has lots of hilly roads. My E is new so tires have lots of threads. What's the air pressure you keep in your tires? Mine were around 35psi cold this morning. Thanks.
