Features of WTD Tires : Deep original tread depth: Keep stones and debris out of the grooves to help resist irregular wear and enhance durability. Sidewall protector bars: Help shield the casing from scrubbing and curbing, while maintaining a smooth, comfortable ride at highway speeds.Casing innovations: Z environment 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 retread ability. 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 retread ability. Serpentine groove pattern: Designed specifically to reduce premature shoulder step-down and irregular wear, further preserving overall tread life. Ultra-Wide top steel belt: Increases rigidity across the entire tread surface, for enhanced durability and to avoid casing damage. Unique rubber compound: Produces stronger, more pliable rubber that improves treadwear and provides low rolling resistance for better fuel efficiency.
