A true workhorse designed to deliver longer treadwear, low rolling resistance and enhanced traction. Keep stones and debris out of the grooves to help resist irregular wear and enhance durability. Help shield the casing from scrubbing and curbing, while maintaining a smooth, comfortable ride at highway speeds. Zenvironment technology allows us to predict changes in tire shape that occur in early stages of wear, resulting in stabilized performance, providing longer casing life and better retreadability. Prevent stones from traveling to the bottom of the grooves, reducing damage to the casing by 25% to ensure high durability and retreadability.
