A tire comprising: a tread portion being divided into four land portions (11, 12, 13, 14) by one circumferentially extending crown main groove and two circumferentially extending shoulder main grooves (5, 6) arranged one on each side of the crown main groove; the four land portions (11, 12, 13, 14) comprising two crown land portions (7, 11, 12) disposed one on each side of the crown main groove; each of the crown land portions (7, 11, 12) being provided with first crown lateral grooves each extending from the crown main groove and terminating within the crown land portion and second crown lateral grooves each extending from the adjacent shoulder main groove (5, 6) and terminating within the crown land portion; and in each of the crown land portion (7, 11, 12), the first crown lateral grooves and the second crown lateral grooves extending at least to an axial center location of the crown land portions (7, 11, 12), wherein the tread portion has a designated mounting direction to a vehicle to define an outboard tread edge (To) to be located on an outboard of a vehicle when the tire is mounted to the vehicle and an inboard tread edge (Ti) to be located on an inboard of the vehicle when the tire is mounted to the vehicle, and in the crown land portion located on a side of the inboard tread edge (Ti), the first crown lateral grooves and the second crown lateral grooves extend beyond the axial center location of the crown land portion, characterized in that the crown land portion located on a side of the outboard tread edge (To) is provided with semi-opened sipes each extending from the crown main groove toward the outboard tread edge (To) and terminating within the crown land portion. a tread portion being divided into four land portions (11, 12, 13, 14) by one circumferentially extending crown main groove and two circumferentially extending shoulder main grooves (5, 6) arranged one on each side of the crown main groove; the four land portions (11, 12, 13, 14) comprising two crown land portions (7, 11, 12) disposed one on each side of the crown main groove; each of the crown land portions (7, 11, 12) being provided with first crown lateral grooves each extending from the crown main groove and terminating within the crown land portion and second crown lateral grooves each extending from the adjacent shoulder main groove (5, 6) and terminating within the crown land portion; and in each of the crown land portion (7, 11, 12), the first crown lateral grooves and the second crown lateral grooves extending at least to an axial center location of the crown land portions (7, 11, 12), wherein the tread portion has a designated mounting direction to a vehicle to define an outboard tread edge (To) to be located on an outboard of a vehicle when the tire is mounted to the vehicle and an inboard tread edge (Ti) to be located on an inboard of the vehicle when the tire is mounted to the vehicle, and in the crown land portion located on a side of the inboard tread edge (Ti), the first crown lateral grooves and the second crown lateral grooves extend beyond the axial center location of the crown land portion, characterized in that the crown land portion located on a side of the outboard tread edge (To) is provided with semi-opened sipes each extending from the crown main groove toward the outboard tread edge (To) and terminating within the crown land portion.
