A tread for a tire , the tread comprising: a first circumferential groove extending in a circumferential direction (C) of the tire , when the tread is applied on a tire ; a second circumferential groove extending in the circumferential direction (C) of the tire , when the tread is applied on a tire ; a third circumferential groove extending in the circumferential direction (C) of the tire , when the tread is applied on a tire ; and a fourth circumferential groove extending in the circumferential direction (C) of the tire , when the tread is applied on a tire , the first, second, third, and fourth circumferential grooves defining first, second, third, fourth, and fifth ribs ; the second and fourth ribs including lateral grooves and lateral sipes , the lateral grooves and the lateral sipes each extending in a first angled direction relative to the axial direction (L) of the tire when the tread is applied on a tire and preferably each extending fully across the respective rib , wherein two of said lateral sipes are disposed circumferentially between each pair of lateral grooves , one of the two lateral sipes 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 , the other of the two lateral sipes 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 , the first direction being oriented opposite the second direction; characterized in that the first rib includes a secondary groove circumferentially extending completely around the first rib and/or in that the fifth rib includes a secondary groove circumferentially extending completely around the fifth rib . a first circumferential groove extending in a circumferential direction (C) of the tire , when the tread is applied on a tire ; a second circumferential groove extending in the circumferential direction (C) of the tire , when the tread is applied on a tire ; a third circumferential groove extending in the circumferential direction (C) of the tire , when the tread is applied on a tire ; and a fourth circumferential groove extending in the circumferential direction (C) of the tire , when the tread is applied on a tire , the first, second, third, and fourth circumferential grooves defining first, second, third, fourth, and fifth ribs ; the second and fourth ribs including lateral grooves and lateral sipes , the lateral grooves and the lateral sipes each extending in a first angled direction relative to the axial direction (L) of the tire when the tread is applied on a tire and preferably each extending fully across the respective rib , wherein two of said lateral sipes are disposed circumferentially between each pair of lateral grooves , one of the two lateral sipes 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 , the other of the two lateral sipes 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 , the first direction being oriented opposite the second direction; characterized in that the first rib includes a secondary groove circumferentially extending completely around the first rib and/or in that the fifth rib includes a secondary groove circumferentially extending completely around the fifth rib . <EOS>
