Winter tires (not studded) really are amazing. I live near DC, so don't normally use them (we don't get enough snow to bother - just stay home for a day or two and it's melted).
But, when I had a Miata (small RWD sports car), I did use them and they made the car one of the best snow vehicles I've owned. Better than the AWD Lexus SUV we owned at the time for sure.
