Has anyone had any experience driving in snow with the Michelin Energy Saver A/S tires that come with the car. They are supposed to be all-season tires, but I have my doubts about how they perform in snow. It has not snowed here yet. Any recommendations on which snow tires to get for this car? Is it safe to unmount the current tires and remount snow tires each year? I did that on a previous car, eventually one of the tires failed to remain inflated after a few years. I wonder if a set of four tires will fit in the car (in the back seat) if I have the current ones removed.
