NEXEN's N'Fera AU7 is designed with absorbent material on the inner parts of the tire to reduce noise in the vehicle interior. In tests, it has reduced noise levels by more than 15 percent compared to similar tires. The 5 Optimal variable pitch blocks for dispersing the pattern noise reduce the negative pressure and generate a soft tone, thereby ensuring a silent comfortable ride. The N'Fera AU7 also improves handling and driving performance on wet surfaces and improves stability on straight roads.
