A tread for a tire is disclosed. The tread (2) comprises a center rib (4) formed by two circumferential main grooves (3) extending along a tire circumferential direction in a center of a tread width direction, each circumferential main groove (3) having the same axial distance (W1) from a tire equatorial plane (CL) of the tread (2). The center rib (4) further has a plurality of first main inclined grooves (15) and a plurality of second main inclined grooves (16), the first and second main inclined grooves (15, 16) being inclined oppositely with respect to the tire circumferential direction such that the main inclined grooves (15, 16) become distanced from the tire equatorial plane from trailing edges in a tire rotational direction toward leading edges; the trailing edges of the first main inclined grooves (15) connecting with one circumferential main groove (3), while the trailing edges of the second main inclined grooves (16) connect with the other circumferential main groove (3). The first and second main inclined grooves (15, 16) are arranged such that mutual leading edges thereof are disposed alternately in the tire circumferential direction, extend axially beyond the tire equatorial plane (CL). The first and second main inclined grooves (15, 16) (i) define two zigzag shaped central grooves (17, 18) extending along the tire circumferential direction, one zigzag shaped central groove (17) being disposed on one side of the tire equatorial plane (CL) and the other zigzag shaped central groove (18) being disposed on an opposite side of the tire equatorial plane (CL) or (ii) define a zigzag shaped central groove extending along the tire circumferential direction, the zigzag shaped central groove being completely disposed on one side of the tire equatorial plane (CL).
