Excellent adherence to any surface, and a perfect fit for a vehicle designed for off-road use. On asphalt and rolled snow, they travel without making a sound; on ice, at a decent speed and uniform control, they do not slip; off-road, as much as they had to go, they always managed to get by with a bang. They begin their journey on an icy surface but manage to keep their footing. They are unconcerned about the snow-chemical mixture that is on the track.
