The NT850 was designed using a state-of-the-art virtual computer simulation process that allows Nitto to see how the tire will perform in various environments, while reduced rolling resistance was achieved using an all-new tread compound. Through virtual and real-world testing, Nitto was able to identify key elements to achieve all-season performance. The NT850 was then built using a patent pending automated manufacturing system, which improves uniformity over conventional manufacturing. Utilizing these technologies the NT850 provides a smooth and quiet ride with the benefit of reduced rolling resistance, making it a tire that you can count on.
