Below is info from the manufacture… Amazing traction for winter riding. The aggressive tread design and lug pattern prevents snow and ice build-up on the tire. The 100 tungsten-carbide spikes bite into the snow and ice, giving you the confidence to ride no matter what the weather. Perfect winter tire. The spikes are not on the tread center; but arranged on the sides in the area of greatest contact pressure. When properly inflated the tire can also be used under normal, ice and snow-free, road conditions. By lowering the air pressure the tire gains optimum grip on icy roads.
