The polyester cord casing optimizes the tire's shape and keeps the tire closely following the road surface at all times. This decreases the road vibrations felt in the vehicle's cabin. The tread design's closed shoulder pattern, on the other hand, manages to reduce the road noise generated while the tires are in motion. The closed shoulders prevent the airwaves from entering the tire's footprint and coming into contact with them. In this manner, the road noise is not generated, which ensures a quiet and enjoyable driving experience.
