The Quatrac Pro is Vredestein's Grand Touring All-Season tire developed for the drivers of sedans, coupes, crossovers and SUVs who want a refined tire that combines luxurious comfort with high-performance grip and handling in dry and wet conditions, plus premium light snow traction. The Quatrac Pro meets industry severe snow service requirements and is designed to be a one-tire solution for drivers in environments that experience all four seasons, but don''t receive sufficient snowfall to require a dedicated winter tire.The Quatrac Pro features a high-resin, high-silica tread compound molded into a variable condition-focused, asymmetric pattern. The outboard shoulder and first rib are designed for traction, handling and steering precision in dry and wet conditions, with low void ratio and large, stiff tread blocks. The inboard rib and inside shoulder are tuned for confident performance in wet and wintry conditions, with wide, circumferential grooves and lateral notches to evacuate water and slush from the contact patch, along with high-density, winter-focused zigzag sipes that help deliver the traction needed to receive the three-peak mountain snowflake symbol (3PMSF).Internal construction of the Quatrac Pro consists of a single-ply polyester casing supporting two steel belts. A polyamide reinforcement aids in handling performance and provides high-speed durability.Note: While non-winter tires featuring the three-peak mountain snowflake symbol (3PMSF) 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.
