Well, on the one hand, all-season tires are definitely convenient, especially if they're actually suitable for the area where you live and drive regularly. If the roads are almost always clear, with no snow, and rain is pretty much the worst weather you get, I think they're a good option. I've just gotten used to switching from summer tires to winter ones and then back again. Besides, I usually combine my tire change appointment with routine maintenance, so I don't have to worry throughout the next season that I've overlooked something and something might start breaking down.
