A pneumatic tire tread contains at least one central bar and grooves. The central bar is of an irregular shape, asymmetrical hollows and cuts are made therein, the zigzag grooves are located on two sides of the bar, which divide the surface onto two middle and two outside circumferential rows. The outside rows pass into the tire shoulder, in the rows the transverse grooves are made, which are made in the form of a smooth curve and expand toward the tire shoulder and divide the rows onto elements in the form of solid blocks, in which parallel cuts are located. The elements of middle rows are made in the form of irregular rhombs, divided by the grooves, and each of which has the zigzag hollow, dividing thereof into two parts, in each of which the cuts are made. |
