- Deep Original Tread Depth - Keep stones and debris out of the grooves to help resist irregular wear and enhance durability. - Serpentine Groove Pattern - Designed specifically to reduce premature shoulder step-down and irregular wear, further preserving overall treadlife. - Sidewall Protector Bars - Help shield the casing from scrubbing and curbing, while maintaining a smooth, comfortable ride at highway speeds. - Ultra-Wide Top Steel Belt - Increases rigidity across the entire tread surface, for enhanced durability and to avoid casing damage. - Casing Innovations - 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. - Unique Rubber Compound - Produces stronger, more pliable rubber that improves treadwear and provides low rolling resistance for better fuel efficiency. - Block-Shaped Stone Guards - Prevent stones from traveling to the bottom of the grooves, reducing damage to the casing by 25% to ensure high durability and retreadability.
