The Quatrac Pro+ is Vredestein's Grand Touring All-Season tire developed for the drivers of sedans, coupes, crossovers and SUVs looking for a tire that joins luxury, comfort and style with responsive handling in the dry and wet alongside high-level capability in icy, snowy conditions. The Quatrac Pro+ is designed as an all-weather tire to meet industry severe snow service requirements qualifying for the three-peak mountain snowflake (3PMSF) symbol alongside its all-season performance. The Quatrac Pro+ takes a high-silica/resin compound and molds it into an asymmetric tread pattern designed to perform in year-round weather conditions. The broad outboard shoulder works in conjunction with a lower void ratio and large, stiff tread blocks to optimize dry handling and performance. The inboard rib and shoulder offer dependable wet and winter performance thanks to wide grooves and diverging lateral channels to move water and slush away from the contact patch. The tread compound maintains low temperature flexibility for control and grip in cold weather, with specially designed sipes in the center ribs for effective snow traction. 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 (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.
