After second snowstorm last week I could test the tires on black ice. While driving safely on town and on a short highway I couldn't feel any skidding at all. Then I went to a big parking lot I knew empty at that time. I wanted to try a bit more sudden turns over the ice. Driving inside the parking lot I did faster steering and breaking movements. The Hakkapeliitta R2 SUVs responded exceptionally well. I could tell that in very sudden turns or stops the SUV's inertia started a fishtail motion but the tires responded in a second with a fantastic grip on the ground. Now I know that in a winter potencial eventuality these tires are going to highly contribute to the passengers' safety and protection of the fine music equipment I usually travel with.
