Performance winter tires like Bizzaks and Alpin command higer rating in all areas such as dry, comfort, tread than original 4-season tires.
Can anyone tell me if one can drive these winter tires in summer/use them as if they were 4-season tires and therefore saves time and cost to change tires in summer ?

 

Nope, they will wear way to fast on the hot pavement, becuase the rubber of a winter tire is a softer compound, but more importantly, your car will handle like sh*t and the tread pattern is really ulgy.
