There are two common myths about winter tires. One is that they're only good on snow or ice. The other is that having them on when there's no snow on the ground will wear them out. We tested both theories at their illogical extreme: the racetrack.

And we found out they're wrong. Very wrong. Jack Baruth flogged the living hell out of a set of Dunlop Wintersports with a Ford Focus ST at Putnam Park Raceway, and his conclusions might surprise you.
