Journeyguy, I run a nokian true all season on my 2011 535i. Reside in Upstate NY, where we experience similar weather to Ohio. These tires (link below) are very good for winter, but not so good for Summer performance. I find them mushy when the weather is hot. They get down the road, but they don't look great on the car. They are a real middle of the road alternative if you don't want to spend money for dedicated Winter set of rims and snows. But, as reported above, I made the decision to buy dedicated Winter set up for my 2009 X5 3.0 because I found used set at a reasonable price on this forum. When I was looking recently, I had almost bought from another member, when a local set came up here. I don't think you'll be too bad off with your current tires, but you may have to wait a couple of days in the season to let the plows remove snow and then you will be fine.
