Abstract: A tread for motor vehicle tires having circumferential grooves (3) and transverse grooves (4), a plurality of tread blocks (5, 6) circumferentially spaced apart to form two shoulder rows (5) and at least one central row (6) located between the shoulder rows. Each block (5, 6) is provided with one or more sipes or slits (11, 12) that are rectilinear and inclined with respect to the axis of rotation of the tire (2). The sipes (11, 12) of the blocks (5, 6) which constitute each of the shoulder and central rows are parallel to one another. The sipes (12) of the central rows (6) have an inclination, with respect to the axis of rotation, that is greater than the inclination of the sipes (11) of the blocks (6) which constitute the shoulder rows. This arrangement of the sipes (11, 12) substantially reduces the rolling noise of the tire.

Abstract: A tire comprises a tread portion provided with a first block provided with a first sipe which extends zigzag in a cross section orthogonal to the sipe length direction, and extends zigzag in a cross section parallel to the ground contacting top surface of the first block. The first sipe is divided into a first portion and a second portion by a tie bar. The sipe bottom in the first portion communicates with a first wide portion. The sipe bottom in the second portion communicates with a second wide portion. The first wide portion comprises an outer portion and an inner portion. The outer portion is formed by a pair of first arcuate groove wall portions. The inner portion is formed by a pair of second arcuate groove wall portions.
