Why? I understand that summer only tires may give a slight performance over all seasons. But they do make higher performance all season tires that are about the same price. I am in the process of picking up a sedan that comes with summer only tires. This means that they should not be used below 50 degrees and are an absolute hazard in anything below freezing. Now I have to go out and spend a grand on the right tires for my North Atlantic climate. Great.
