The improved and maintained road contact increases the steering responsiveness and the driving stability. In other words, it stabilizes the structure against the driving pressure affecting it, while the steering response to the driver's instructions becomes faster and more precise. The larger outer shoulder tread area heightens the number of biting edges, which grip the road surface during cornering, to improve the maneuvering capability. The optimal asymmetric tread design boosts the tire's road contact and heat build-up prevention, which upgrades the high speed driving durability and experience.
