A tread for a tire (1) is disclosed. The tread (100) comprises first, second, third, and fourth circumferential grooves (10, 20, 30, 40) defining first, second, third, fourth, and fifth ribs (110, 120, 130, 140, 150). The second and fourth ribs (120, 140) include lateral grooves (124, 144) and lateral sipes (126, 146), the lateral grooves (124, 144) and the lateral sipes (126, 146) each extending in a first angled direction relative to the axial direction (L) of the tire (1) when the tread (100) is applied on a tire (1) and preferably each extending fully across the respective rib (120, 140). Two of said lateral sipes (126, 146) are disposed circumferentially between each pair of lateral grooves (124, 144), one of the two lateral sipes (126, 146) extending in a first direction and, when moving along the first direction, having a first width transitioning to a second wider width at or adjacent to a lateral mid-point of the respective second and fourth rib (120, 140), the other of the two lateral sipes (126, 146) extending in a second direction and, when moving along the second direction, having a first width transitioning to a second wider width at or adjacent to a lateral mid-point of the respective second and fourth rib (120, 140), the first direction being oriented opposite the second direction.
