This, along with the steel belt construction, secures the tire's structure and prevents deformation under the high speed driving pressure. In this manner, the tire is capable of safely performing even at high speeds as the structure does not deform under the driving pressure affecting the tire. The jointless tread ply and the directional tread design together ensure a stable drive and better steering. In other words, they stabilize the tire's structure against the driving pressure affecting it and increase the steering responsiveness and accuracy to the driver's commands. The shoulder tread blocks succeed in upgrading the maneuvering and cornering capability in all conditions as they increase the number of biting edges that firmly grip the road surface at all times. The result is an easily controllable tire.
