The Encompass AW01 is Nokian Tyres' Grand Touring All-Season tire designed for drivers of family sedans, coupes, crossovers and SUVs who want a smooth, comfortable ride with confident traction for the variable conditions experienced by North American drivers. The Encompass AW01 is designed as an all-weather tire to meet industry severe snow service requirements for the three-peak mountain snowflake (3PMSF) symbol alongside its all-season performance. The Dual Zone Asymmetric tread design is molded from an advanced all-season compound engineered to balance grip in slippery conditions with consistent dry traction and tread life. The robust shoulder blocks feature Groove Lifts which help support the tread elements for increased stiffness and enhanced cornering characteristics under load. The intermediate ribs maintain significant longitudinal surface area for quickened steering response and consistency under heavy braking. Further inboard, deeper notches link the circumferential grooves and become more plentiful, increasing hydroplaning resistance and control in inclement weather. Generous sipes throughout the pattern create biting edges for grip in slippery conditions on slick roads, while the numerous lateral notches and zig-zag circumferential grooves help retain snow, generating the winter traction required to earn the 3PMSF symbol. The Encompass AW01's internal construction features Aramid Sidewall Technology which utilizes an exceptionally strong fiber material to help protect against punctures and impact damage from road hazards. Nokian Tyres' Driving Safety Indicator is molded into the center rib and displays the approximate tread life remaining, allowing drivers to quickly gauge appropriate tread depths for inclement weather. Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol may provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.
