Living here in Fort McMurray, Alberta, Canada. Get snow tires for sure. If your area has alot of hills, studded in the rears can help. Up here I've been driving the BRZ to almost -40 which turns everything to just ice. For now I have X-Ice 2s all around but I can still feel the back end letting go a little when I'm going up a slightly steeper hill.
Next winter, I'm going to get studded ones for the rear. Only time it really sucks to have the car out is when we get a couple inches of snow and the roads haven't been plowed yet.
Other than that, if the temps are around -10 or so, regular winter tires are great and will work! The BRZ is sooo much better than the old 89' 240sx I had back in the day. Used to always carry a shovel in the back of the old hatch just in-case
But yea just drive carefully to the conditions of the road and you should be fine!
