The W.drive V905 is Yokohama's Performance Winter / Snow tire developed for the drivers of sports cars, sports coupes, high performance sedans and performance-tuned SUVs looking for high-speed winter driving performance along with confident traction and handling in dry and wet conditions.A specialized, high-silica compound infused with Orange Oil allows the W.drive V905 to remain flexible and provide traction across a wide range of temperatures. The directional tread pattern with wide slanting grooves helps to evacuate water and slush from the contact patch for hydroplaning resistance, and the Triple 3D sipes create biting edges for traction on slick surfaces while increasing tread block stiffness for confident handling in dry, wet, or snowy conditions.Internal construction of the W.drive V905 consists of a two-ply polyester casing to help balance ride comfort and durability, and the two wide, steel belts are reinforced by a nylon cap ply to aid handling responsiveness and deliver high-speed capability.W.drive V905 tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.Note: Snow platform indicators (the equivalent of "snow wear bars") are molded into the W.drive V905's tread grooves to inform the driver when ice and snow traction will be reduced as the tire's tread reaches the point where the remaining tread depth becomes less effective in deep snow.Install W.drive V905 tires in sets of four only.
