Advanced Winter Technology Delivers Advanced Winter Traction Building on the exceptional success of the Ice Guard IG10, the all-new Ice Guard IG20 represents a great leap forward in winter traction technology. Designed to cut through the watery film on ice that causes micro-hydroplaning, the IG20 features Yokohama's over a billion absorptive carbon flakes and more than 5 billion resin-coated shelled microbubbles. The tread design has been refined to offer better grip during acceleration, cornering and braking in the worst winter weather, including in slush and snow and on ice. The IG20 has also been optimized to provide long-lasting wear and low road noise.
