A tire comprises a tread portion comprising at least one land portion having a first longitudinal edge, a second longitudinal edge, and a ground contacting top surface therebetween. The land portion is provided with first sipes, second sipes and third sipes. Each first sipe is inclined with respect to the tire axial direction to a first direction. Each second sipe is inclined with respect to the tire axial direction to a direction opposite to the first direction. The third sipe comprises a first oblique portion extending from the first longitudinal edge and inclined to the first direction, and a second oblique portion extending from the second longitudinal edge and inclined to a direction opposite to the first direction.
