To start off, We live in California where we do not need dedicated winter tires. This is my wife's daily and 95% of our driving through winter is 50-70 degrees, but we do have a cabin in the mountains and go snow skiing. So we need an all season tire to get up to the mountains. When we purchase the Stelvio we figured we would get through our first six months on the P Zeros and change them out to an all season during winter. Just an FYI to everyone out their who live in a climate like ours. Their are no all season tires available for this vehicle. Do your homework if you live in a climate where switching back and forth to winter tires don't work. We are having to look at either selling the Stelvio which we love or buying a dedicated ski vehicle. I wish I would have looked into this when I was purchasing the vehicle.
