I currently have 235/50/18 all seasons on my X3. I wanted to go to a true winter tire for the winter. Any recommendations for me. I live in Colorado and I leave the house really early before anything is really plowed. I want something very reliable. I went to Discount tire and they told me about the Hanacok tire. They said it only last one season but do very well in the snow. They run about $200 a pop. Any ideas?
