The Yokohama BluEarth 4S AW21 is an all-season touring tyre designed for year-round driving across various weather conditions. This tyre features a directional tread pattern with divergent V-grooves and crossing narrow grooves that efficiently channel water away and reduce aquaplaning risk. Key technologies include a special silica compound for enhanced cold-weather grip, a low-heat generated under-tread layer to reduce rolling resistance, and densely grouped grooving for improved water evacuation. The tyre demonstrates strong performance in snow and ice conditions with excellent braking, though it exhibits higher noise levels and higher rolling resistance that may impact fuel efficiency compared to some competitors. Load and speed ratings vary by size, with examples including 82T, 82H, 88H, and 91H designations. The BluEarth 4S AW21 is recommended for passenger cars, small and compact cars, mid-size sedans, and modern SUVs and CUVs.
