^^^^^If you read my first post you see that I drive 90% of the time on the highway. Commuting is easy enough on the highway that I almost considered running a CTS-V as my daily driver. We do get substantial storms where I live, but I guess the plowing and maintenance is good enough to not require winter tires. Are winter tires better in the snow and ice, yes. Are they needed to keep you out of a ditch, no. I have not once come up short in reaching my destination, even going back to the days of running all seasons on a RWD. And this is even with me chasing the big snow storms to the mountain to go skiing. I think it is just all based on what you are comfortable with.
