I drive with all season tires (marked M+S) all year, and I'm happy. A lot of people tell me it is a bad idea, I should buy both summer tires and winter tires, because the temperature gets up to +30C in Summer and down to -15C or even -25C in Winter, but well, I don't see why should do that. If manufacturers make tires suitable for all seasons, why shouldn't I use it, lol. From my driving experience, driving skills are more important than tires in snowy weather. Of cource, summer tires are no good on snow and it is very dangerous, but all season tires are ok if you know how to drive on snow.
