The VikingContact 7 is Continental's Studless Ice & Snow winter tire developed for drivers of sedans, crossovers, coupes and minivans looking for enhanced winter confidence through advanced technology. Designed to deliver excellent traction in wintertime slush, snow and ice plus reliable wet performance and secure dry-road handling, the VikingContact 7 is optimized for a variety of winter weather.The specialized Nordic compound of the VikingContact 7 utilizes canola oil to remain flexible and adapt to snowy or icy conditions, and active grip silica enhances wet performance and braking. The compound is molded into an intelligent pattern with a groove network designed to create a direct path to evacuate water and slush from beneath the contact patch. The optimized void ratio ensures there is always a high volume of rubber on the road for confident tracking and high-speed control. Solid linkages and special interlocked block bridges stabilize the tread pattern while also keeping grooves open for water and slush drainage. The VikingContact 7's 3D sipes feature varying thicknesses. While all the sipes create biting edges for grip in slippery conditions, the wider sipes form snow pockets that collect snow from the surface and hold it in the pattern, creating snow-to-snow traction for improved performance. Grip Edges on the outside of the tread blocks grab into snow and effectively increase the contact area of the tire, further enhancing traction on snow- and ice-covered roads.VikingContact 7 Studless Ice & Snow tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.Install VikingContact 7 tires in sets of four only.
