A pneumatic tire tread contains at least one central bar and grooves. The central bar has cuts, alternating with dead hollows of variable size, which shape the bar as a set of oblique rhombs connected by bridges. Two circumferential grooves are located on each side of the bar and divide the surface onto four rows. In the outer rows the transverse curvilinear grooves are made, which expand toward the tire shoulder and divide thereof onto elements in the form of solid blocks, in which the cuts are located. The elements of inner rows are made in the form of parallelograms, two sides of which are straight, and two - are closed by arcs. At that each element has the dead groove with expanding on the end and the cuts. |
