The Assurance DuraPlus 2 gives you the freedom to go further with Tread Life Technology. Tread Life Technology featuring an innovative tread design and compound allows your tires to go further with extended mileage performance. A highly durable sidewall increases tire robustness to better resist sidewall impacts. New tread pattern design and construction combine to minimize interior noise throughout tire life. Benefits & Features- Innovative Tread Design & Cavity: New symmetrical tread pattern designed with a wider cavity shape and narrower grooves, increases wearable rubber volume. This ensures a longer lasting tread life. Innovative Tread Design: Symmetrical tread pattern design gives greater flexibility in tire rotation thereby improving tire lifespan. Enhanced Cavity Shape: Enhanced cavity shape enables a more squarish and balanced footprint to maintain a larger contact patch and reduces contact pressure. This leads to extended mileage performance. Re-formulated Long Lasting Compound: A re-formulated compound with high wear resistance to deliver longer lasting mileage performance. Enhanced Sidewall: Built with 2 layers of high modulus low shrinkage ply material in the sidewall to ensure better resistance against external impacts. The sidewall compound is further upgraded to enhance long term resistance against environmental influences. Re-formulated Long Lasting Compound: Enhanced cavity shape at the lower sidewall area reduces the stress and strain within the tire. Innovative Tread Design: Narrower lateral grooves and closed design reduced the noise caused by air pumping. Optimized groove angles and pitch sequence to reduce impact noise.
