Additionally, the SP 4000 T's circumferential rain groove tread provides improved wet-weather performance.
The SP 4000 T's triangular groove pattern is specifically designed to offer enhanced grip in snowy/icy conditions while its rigid tread blocks ensure greater steering stability and control during hard cornering in dry-weather/summer conditions. Meanwhile, the SP 4000 T's circumferential rain groove tread design ensures that rain is quickly evacuated, ensuring greatly improved wet-weather performance and a reduced chance of hydroplaning.
