Ironman RB-12 NWS 225/75R15 102SPassenger Tire

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.
