Tire Size: P215/45R18 (Rim Not Included) Model Fits GRAND SPORT A/S It features four wide longitudinal grooves that offer good drainage by evacuating the water from the tire’s footprint and decreases the chances of hydroplaning. It's sipe design helps to reduce tire noise, while closed slanted grooves improve steering ability and straight-line performance at high speeds. Technology of pitch width optimization and sequence effectively reduces noise resonance that results in quieter ride. Features:

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: 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.
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.
Serpentine groove pattern: Designed specifically to reduce premature shoulder step-down and irregular wear, further preserving overall treadlife.
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.
