The Continental ExtremeContact DWS tire features traction grooves with biting edges or teeth that lock the snow in the tread keeping traction and preventing sliding on top of the snow. This gives better performance and traction in snow conditions. For more information and to purchase these tires visit http://www.tirebuyer.com
